Hi All,
I have a PX5 radio that was supplied with fittings for 2006 Toyota RAV4 , sadly it didnt come with a CANBOX and supplier was not able to provide one that matched, I managed to get my hands on a Canbox for VW unit and decided to reverse engineer the unit.
Here are my findings.
Code:
Pinouts
1--2--3--4--5--6--7--8
9--10-11-12-13-14-15-16
1 GND 9 B+
2 CANH 10 CANL
3 EMPTY 11 ACC
4 EMPTY 12 EMPTY
5 EMPTY 13 EMPTY
6 EMPTY 14 EMPTY
7 MCU_RXD_CAN 15 EMPTY
8 EMPTY 16 MCU_TXD_CAN
On power up the device sends a hex packet to TX Uart of the board (RX of the head unit) at 38400 baud,
the packet is as follows
Code:
0x0,
0x2E,0x21,0x5,0x0,0x10,0x0,0x0,0x0,0xC9
0x2E,0x21,0x5,0x0,0x10,0x0,0x0,0x0,0xC9,
0x2E0x21,0x5,0x0,0x10,0x0,0x0,0x0,0xC9,
0x2E,0x21,0x5,0x0,0x10,0x0,0x0,0x0,0xC9,
0x2E,0x22,0x4,0x1,0x1,0x1,0x1,0xD5,
0x2E,0x22,0x4,0x1,0x10x1,0x1,0xD5,
0x2E,0x22,0x4,0x1,0x1,0x1,0x1,0xD5,
0x2E,0x22,0x4,0xFE,0x2,0x1,0x1,0xD5,
0x2E,0x23,0x4,0x1,0x1,0x1,0x1,0xD4,
0x2E,0x23,0x4,0x1,0x1,0x1,0x1,0xD4,
0x2E,0x23,0x4,0x1,0x1,0x1,0x1,0xD4,
0x2E,0x23,0x4,0x1,0x1,0x1,0x1,0xFF,0xFF
Raw Packet
Code:
02E215010000C92E215010000C92E215010000C92E215010000C92E2241111D52E2241111D52E2241111D52E2241111D52E2341111D42E2341111D42E2341111D42E2341111D4FF
packet burst start with 0x0 then each packet start with 0x2e
My Assumption is the box acts as a translator converting each car specific CANBUS/KKL/KLINE/IR-bus protocol into a
pre-defined packet of information that it transmits to the headunit.
if this is confirmed then creating a open source version of the box should be easy within the ease of the cars can system ,
it may also open cars that dont have can bus to still use the canbus system of headunit, eg reading speed to adjust volume , monitor door open to display on screen using arduino.
If anyone has seen a lookup chart or information on the CANBOX/Decoders protocol to/from the headunit I would love the link.
next i will hookup to the headunit itself and send the same codes to see what effect they have.

p.s if anyone knows of a firmware bin for canbus box then please let me know.
*EDIT 30/01/2023*
This is the raise/hiworld/simple soft 20 pin pin-out I am seeing now.
Below is a toyota model that has AVC LAN

Thanks. That is very interesting. I subscribed the topic. In my case I have a problem with my can decoder regarding the panel lights. It is correctly switch on if I manually switch on the headlights, but it doesn't come on if the headlights are in "Automatic" mode. Probably the CAN message in this case is different and is not correctly decoded by the box.

probably this post could help you... it gives some usefull codes, including a sort of CAN Bus monitoring:

Yes, the can ID or $ID in short hand is different for light, auto lights on and dial light turned on. i have fallen pray to this with my RAV4 auto lights, like why my display is dim "oh i put a book on top of the sensor on the dash" , but I chased other bugs before that one became more obvious.

Thanks, I had come across that one and apart from the logcan function most of the other stuff is not valid in this application.
I intend to aim primarily at the protocol between Head unit and CANBOX, not CANBOX to car (as i'am sort of covering that elsewhere) , the CANBOX to car part is one hell of a rabbit hole to go down , not only are varied high level terms thrown around incorrectly or misunderstood in a lot of articles but as soon as the document gets to a level of understanding the information drains off as the commercial applications come forward, imagine cartoon authors eye's turn to ($) ($).
Thats why you dont see much in the way of good open source OBD stuff thats not tied into a specific hardware circle or device type.
J2435 is sort of opening that up but in a poor way, they hiding the CAR part behind a device again so again we dont know what the device is saying to the car.
This is why i wont be really covering much on the car side but more in how we can replicate the canbox functions first of all.
I already have a POC that talks to a ELM327 device via wifi or BT, only the programming the esp2866 lacks full understanding of the car as i have JDM cars, not only is JDM protocols different from euro/US counterparts but the also have sub -divided protocols where a euro/us function will work on 2006-2007 model but not 2008-current, who knows why but that is the way of it.
I also do have some additional information on the protocol that i've have to digest, the last bytes are CRC8 EDIT:twos compliment crc see below, i've confirmed that, so we can calc on fly or use look up table for speed, I also have seen this protocol in my research before into another subject but i cannot place it yet, the $2e start byte is the giveaway and followed by function High byte and low bytes and then data and finally crc, Maybe i'll remember it before someone else does, but we have the base part of the protocol and i already have a POC code that is usable on many devices due to being arduino in nature(just not arduino ide but thats a coders choice),
Now as we already have a schematic floating around with full BOM we could in theory make our own canbox but when checking I found it's based on STM8 which is a older chip and I'am personally more familiar with STM32F series and atmega, sam4c etc so i may re-produce the board using that. Also all of my current in stock hardware that has canbus is all stm32f.
Now some of you might have spotted my glaring mistake, I want the code the to work on anything but i'am building it using stm, well thats only due to the fact i have a quite a few stm's to sacrifice , once i know the code works (HU to canbox & canbox to car) then i can introduce other brands of MCU once i have a validated test bench. What will vary device to device is how you Initiate the CAN, with stm32 chips they have bXcan drivers in f103 chips, for atmega we can use spi based canbus driver chips. Supporting those two functions will be enough to pull in esp/atmega/LT and many other chip makers should someone want to port to their fav brand of chip.
I would also like to support non-obd cars , sensing door open is not that hard and a simple arduino+level converter you can sense doors, speed and more. there's also a few after market steering wheels that have vol dials as wheel as custom car builder wanting to use a wheel from brand A on brand B , who am i to judge where you got your real Lotus F1 wheel from.
Now we do have to cover one subject thats often missed in these discussions, OBD and all it's cousins was ment as Diagnostic first, which means not all cars are happy having a dongle full time on the OBD port, I've seen cummings based vehicles refuse to start unless the OBD is unplugged first, that means the dongle is introducing noise on to the bus, be it in the form of legit data request, eronus data or real electrical noise from not having the BUS resistor .
edit: while trying to solve this "ive seen this before" problem I did find this, very similar,

My head unit isudar h53 also has can box. The car can H and can L connect directly to the box. Between the box and radio there are can rx and can tx. If I go to car choise menu to select car type, after that the unit update the mcu firmware. When this update is done whether the can box is also updated via can rx and can tx lines?
Normally the can rx and can tx signal translated via can chip eg.: tja1050 to can H and can L. If nothing else is in the can box it is not need to update. But the box include ignition ac signal and fix voltage. Because this reason maybe there are much more component in the box than a single can chip.
So my question is if I want to modify one of the can message, enough the head unit update or need to the can box also?
CRC sorted
Ok, so i've sorted the crc out, I can now calc the crc correctly based on this :-
Code:
uint8_t data_packet[] ={0x41,0x2,0x01,0x80};
uint8_t crc_mod(uint8_t car_array[],int datasize)
{
int checksum=0;
for (int i = 0; i < datasize; i++)
{
checksum = (checksum + car_array[i]) & 0xFF;
}
return (256 - checksum & 0xFF)-1;
}
void main()
{
uint8_t data_crc=crc_mod(data_packet,sizeof(data_packet));
Serial.print(data_crc,HEX);
}
and of course the final packet array will be :-
0x2E,0x41,0x02,0x01,0x80,0x3B
or
START_BYTE,PKT_BODY,sizeof(MIN_DATA_SIZE),FILLER_BYTE,SEAT_BELT,crc_mod(PKT_BODY,sizeof(MIN_DATA_SIZE),FILLER_BYTE,SEAT_BELT)
would make up a full packet,
As for the actual data packet i've broken it down to :-
Code:
#define START_BYTE 0x2e
#define MIN_DATA_SIZE 0x2
#define FILLER_BYTE
//buttons
#define PKT_BUTTON 0x20
#define HU_VOLUME_UP 0x1
#define HU_VOLUME_DOWN 0x2
#define HU_NEXT 0x3
#define HU_BACK 0x4
#define HU_BT_ON 0x5
#define HU_MUTE 0x6
#define HU_HOME 0x7
//body functions -
#define PKT_BODY 0x41
#define FL_DOOR 0x1
#define FR_DOOR 0x2
#define RL_DOOR 0x4
#define RR_DOOR 0x8
#define BOOT_DOOR 0x10
#define PARK_BRAKE 0x20
#define WIPER_FLUID 0x40
#define SEAT_BELT 0x80
I'am going to assume there are different packet ID's other than 0x20 and 0x41 out there eg AC, windows , lights see next post, Also i've not optimized the packet structure or definitions and i've not pasted all the body definitions i've found, some are unconfirmed or contradicting.
I'am going to tidy up the code so i can share it and hope it will make more sense once i've removed all my test rubbish but I initially have the arduino acting on packets from the device (CANBOX) and I can now build a packet with crc being calculated runtime, have not tested what happens when i send to the box yet as my setup is very , ahem, primitive due to desk space limitations and my current setup includes :-
1x canbox
3xstm32 blackpills (one is acting as HU, one is acting as CAR CAN and one ties uarts together)
1x rigol ds1054z scope
anyway, more to come.
darkspr1te
Ok,so in the prior post we spoke about the basic packet so far,
but in my first post I pasted some data from my box
Code:
0x2E,0x21,0x5,0x0,0x10,0x0,0x0,0x0,0xC9
0x2E,0x21,0x5,0x0,0x10,0x0,0x0,0x0,0xC9,
0x2E,0x22,0x4,0x1,0x1,0x1,0x1,0xD5,
0x2E,0x22,0x4,0xFE,0x2,0x1,0x1,0xD5,
0x2E,0x23,0x4,0x1,0x1,0x1,0x1,0xD4,
0x2E,0x23,0x4,0x1,0x1,0x1,0x1,0xFF,0xFF
So we also know that packet size can change , maybe this is the difference between brands (RAISE is a common one i see and mine has that written on PCB) , I dont have the box for my unit but I have seen a image of it around, i'll try to post it on the CANBOX Types post and then refer here.
I also see a lot of duplicate transmissions too so next step is to listen to the device while connected to a real HU to sniff for packet OK response, again that is a assumption on my side.

Excellent work. I have a lot of functionality on my 2010 jeep grand Cherokee (tpms, front and rear radar, etc.) That aren't displayed by the head unit....I hope you will find a way to customize it and I finally can use it for my car

Thanks, Yes extended functions will be available even in cars where they may not directly exist. Door open could be emulated by just sensing the door pin, but the electronics for a general car board that could be re-purposed for this I'am not sure exist in a good package.
maybe later on i'll look for a open source obd board that has additional input other than just OBD CAN and can isolate itself from the H/U.
Jeeps are known to me, I grazed my first knuckles on a 4L High output from the willies jeep body & early Cherokee, fun cars if they are not your daily driver.

Door status display, manual headlight switch on, steering wheel commands and Steering angle sensor (dynamic lines in rear view cam) are the unique "CAN" implemented function on my Jeep Grand Cherokee WK head unit CanBus BOX. There are a lot info on the Can Bus that could be displayed on the HU, i.e. external temperature, TPMS, Parking Sensors, Compass, etc.
Any update?

Is this wonderful work abandoned ?
I've not abandoned the project, due to IRL commits and other projects to complete I just had not had the time to return to this, the project is still under development internally but writing the public document side is time consuming and i've not had that kinda time of late.

Canbus firmware file
I don't know if this is still useful for you, but here is a link for a firmware update for a VW-SS-07 VW canbus unit:
https://mega.nz/#!zXJBnQxZ!EOEbuxoIjO3Otyv9hxUuDBzLDuuNRbiMEo9-g2hBfAI
Here are the instructions for using it:
1. Confirm the model of your canbus decoder is VW-SS-07.
2. Download the software onto the root content of your sd card and insert it to the unit.
3. Enter Factory Settings and input the code "canupdates" instead of password.
Here's the page I found it on:

Hi All,
I have a PX5 radio that was supplied with fittings for 2006 Toyota RAV4 , sadly it didnt come with a CANBOX and supplier was not able to provide one that matched, I managed to get my hands on a Canbox for VW unit and decided to reverse engineer the unit.
Here are my findings.
Code:
Pinouts
1--2--3--4--5--6--7--8
9--10-11-12-13-14-15-16
1 GND 9 B+
2 CANH 10 CANL
3 EMPTY 11 ACC
4 EMPTY 12 EMPTY
5 EMPTY 13 EMPTY
6 EMPTY 14 EMPTY
7 MCU_RXD_CAN 15 EMPTY
8 EMPTY 16 MCU_TXD_CAN
On power up the device sends a hex packet to TX Uart of the board (RX of the head unit) at 38400 baud,
the packet is as follows
Code:
0x0,
0x2E,0x21,0x5,0x0,0x10,0x0,0x0,0x0,0xC9
0x2E,0x21,0x5,0x0,0x10,0x0,0x0,0x0,0xC9,
0x2E0x21,0x5,0x0,0x10,0x0,0x0,0x0,0xC9,
0x2E,0x21,0x5,0x0,0x10,0x0,0x0,0x0,0xC9,
0x2E,0x22,0x4,0x1,0x1,0x1,0x1,0xD5,
0x2E,0x22,0x4,0x1,0x10x1,0x1,0xD5,
0x2E,0x22,0x4,0x1,0x1,0x1,0x1,0xD5,
0x2E,0x22,0x4,0xFE,0x2,0x1,0x1,0xD5,
0x2E,0x23,0x4,0x1,0x1,0x1,0x1,0xD4,
0x2E,0x23,0x4,0x1,0x1,0x1,0x1,0xD4,
0x2E,0x23,0x4,0x1,0x1,0x1,0x1,0xD4,
0x2E,0x23,0x4,0x1,0x1,0x1,0x1,0xFF,0xFF
Raw Packet
Code:
02E215010000C92E215010000C92E215010000C92E215010000C92E2241111D52E2241111D52E2241111D52E2241111D52E2341111D42E2341111D42E2341111D42E2341111D4FF
packet burst start with 0x0 then each packet start with 0x2e
My Assumption is the box acts as a translator converting each car specific CANBUS/KKL/KLINE/IR-bus protocol into a
pre-defined packet of information that it transmits to the headunit.
if this is confirmed then creating a open source version of the box should be easy within the ease of the cars can system ,
it may also open cars that dont have can bus to still use the canbus system of headunit, eg reading speed to adjust volume , monitor door open to display on screen using arduino.
If anyone has seen a lookup chart or information on the CANBOX/Decoders protocol to/from the headunit I would love the link.
next i will hookup to the headunit itself and send the same codes to see what effect they have.

p.s if anyone knows of a firmware bin for canbus box then please let me know.

Thanks, I've pulled the files but not yet looked at them, time has been a strange partner of late

Hi darkspr1te ,
Useful topic. Congrats!
So, i had a DIY project and got some information about serial protocol between CANbox decoder and China head unit from your topic.
I have a Volvo XC90 and buy from aliexpress head unit for my Volvo, but when it arrives... There is surprise - CAN decoder did not recognize CAN bus. I asked the seller, but he told me "you need to learn yourself how the CANbus integration works".... Тypical China seller....
After that i open this CANbus decoder and found inside STM32L072, great news, because i'm hardware engineer and my primary job is to design PCBs and write firmware.
Since today i have working CAN bus decoder(i wrote my own FW) with following features:
1. Recognize CAN communication between modules in XC90 and parse messages.
2. Send commands via UART to china head unit. Most of functionality works now - steering wheel buttons, gearbox state(P,R,N,D) this is for rear camera, day - night backlight mode, doors and lids state(open-close).
Today spended two hours to play with CAN analyzer in my car and found message that shown steering wheel angle. Do you know how to send this information via UART to head unit?
I found in your topic following - public static final int CH_CMD_STEERING_WHEEL_ANGLE = 0x29;//方向盘转角信息, but i don't know how to transmit the data in the message.

Hey all
I have the following code to open a socket on Windows Mobile 6.1:
Code:
string hostIP = "192.168.0.2";
IPAddress ip = IPAddress.Parse("192.168.0.2");
int port = 80;
IPEndPoint localEP = new IPEndPoint(ip,port);
Socket listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream,ProtocolType.Tcp);
try
{
listener.Bind(localEP); // socket exception here
listener.Listen(15);
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
The goal is to simply open a socket, so I can develop on top of this and receive web requests but I receive a socket exception on the line where the bind takes place. Any ideas what might be going on?
maybe the options?
serverIPEndPoint = new IPEndPoint( serverIP, serverPort );
listenerSock = new Socket( AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp );
listenerSock.SetSocketOption( SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, 1 );
listenerSock.Bind( serverIPEndPoint );
listenerSock.Listen( 200 );
I have to make the program to where it outputs "You were born on (DD-MM-YYYY, these are the user inputs).
I have everything besides that..can anyone help?
Code:
import java.util.Scanner;
//This program does math
public class Final
{
public static void main(String []args)
{
Scanner in=new Scanner(System.in);
System.out.println("One last test");
System.out.print("Enter your birthday (mm/dd/yyyy): ");
String roar=in.nextLine();
int n1=Integer.parseInt(roar);
String date;
String month, day, year;
String ox=in.nextLine();
String[] s = ox.split("/");
for( String str : s);
System.out.println("You were born on"+day+month+year);
}
}
That is what i have so far, but i need to declare the day, month and year..can anyone help me?
Bump..need help please.

On running your program it shows that you're Strings date, month, day, and year are not initialized. I'm not 100% as I never got far into java, but you should initialize them
Code:
String string = null;
String string = 0;)
once they are initialized it gives another error, basically that you're birthday input of mm/dd/yyyy isn't in the proper format to be an integer. I do not know how to fix that one. My knowledge of java is very basic but I have a feeling that should help you out somewhat.
An easier alternative to what you are trying to accomplish would be to ask the month day and year in separate prompts and assign them to plain integers.
I have a feeling you are doing this for a college class perhaps? I had to do one similar to this thats why I ask.
On another note, you might have better luck finding the help you need on a site that is more geared towards java programming (maybe stack overflow?)
I hope this helps.
Yes, it is my college class.
so far i got this :
Code:
import java.util.Scanner;
//This program does math
public class Final
{
public static void main(String []args)
{
Scanner in=new Scanner(System.in);
System.out.println("One last test");
System.out.print("Enter your birthday (mm/dd/yyyy): ");
String roar=in.nextLine();
int n1= roar;
String date;
String month, day, year;
String ox=in.nextLine();
String[] s = ox.split("/");
System.out.println("You were born on"+s[0]+s[1]+s[2]);
String str;
}
}
Since we have the ICS source can anyone think of the least invasive way to add a mod for it for the stock rom.
(Strange that flac files are associated with the stock media player).
Thinking about just taking the flac patch (or perhaps there is two) putting it into AOSP 2.3.4 and then trying replacing the whole stagefright. Is there a better way to do it. (Its certainly possible now but there may be all sorts of reasons why this may be a bad idea.)
I want to change as little as possible.
(Any proof that its impossible also accepted).
** Edit
Works in Simulator
The diff is attached - need to take external/flac from an ICS checkout.
Think all that is necessary now is to just increment 2 numbers in the framework.
(Maybe another 2 if we want it to work with mtp (And Windows Media Player sync).

Seems to work with the simulator. (Haven't done the MTP part as I am not that bothered about it).
Anyone can help patch the framework for the 62 rom I would be grateful.
(Even better explain how to do it).
This is just a stop gap measure until we get ICS.
(I would have thought anyone who uses baksmali for framework modding etc could do this really easily.)

I don't understand why flac is associated with the media player though at all. (Poor backport for the MTP support ?)
(I will start tomorrow unless someone can explain why what I intend is going to break a feature).
re wrong forum doesn't make sense its blatantly a development question

Given that there are no 2.3.4 AOSP builds working, wouldn't it be easier to patch the CM7 builds? That way you won't have to create and run the whole build yourself.
interesting news about improving battery life:
Lee!!!!
Ive found out where the missing power management options has gone wrong
For some reason HTC misplaced the .apk and put it in /system/bin instead of system/app
You will find it /system/bin/NvCPLSvc.apk and it needs moving to system/app.
For users who already have LeeDroiD installed, use a file manager with root access and move NvCPLSvc.apk from/system/bin to system/app and reboot.

Hi all. There is a one question to developers and for those, who know Android at well. I'm need to add some additional camcorder profile for Mediatek based devices in CamcorderProfile class (frameworks/base/media/java/android/media/CamcorderProfile.java). Something like this:
Code:
public static final int QUALITY_LOW = 108;
public static final int QUALITY_MEDIUM = 109;
public static final int QUALITY_HIGH = 110;
public static final int QUALITY_FINE = 111;
public static final int QUALITY_NIGHT_LOW = 112;
public static final int QUALITY_NIGHT_MEDIUM = 113;
public static final int QUALITY_NIGHT_HIGH = 114;
public static final int QUALITY_NIGHT_FINE = 115;
public static final int QUALITY_LIVE_EFFECT = 116;
public static final int QUALITY_H264_HIGH = 117;
public static final int QUALITY_FINE_4K2K = 123;
public static final int SLOW_MOTION_VGA_120FPS = 2231;
public static final int SLOW_MOTION_HD_60FPS = 2240;
public static final int SLOW_MOTION_HD_120FPS = 2241;
public static final int SLOW_MOTION_HD_180FPS = 2242;
public static final int SLOW_MOTION_HD_240FPS = 2243;
public static final int SLOW_MOTION_FHD_60FPS = 2250;
public static final int SLOW_MOTION_FHD_120FPS = 2251;
public static final int SLOW_MOTION_FHD_240FPS = 2252;
But this is an API modification And when I try to build firmware i get message about inadmissibility of API editing. Does anybody knows how to add this profiles to Camcorder class correctly and build the ROM?
