Has ANYONE been able to successfully read an automotive CANBUS with this? If so would you please share your code? I am not even getting garbled info, it works great with the demo, but NOTHING on an actual bus.
So I have been playing with this board since I got it a few days ago, this is what I learned.
-
when using a ESP8266 with MCP2515 to send standard can messages through the CANBED at max speed to another ESP8266, I get a speed of 320 messages a second. When I go from MCP2515 directly to MCP2515, I can get up to 1811 messages a second.
-
If I put into my car to sniff any traffic I get garbage!!. I know the settings are correct because I can get 1200 messages a second using the MCP2515. I need CAN-FD so I am missing some key messages.
-
The firmware from superwofy doesnât work. I used an STLinkV2, flashed it it didnt work. I used the original firmware from Logon Labs Github and worked. The sources look vastly different so I didnât go much further in this.
-
Being that MCP2515 works with this board, I think there is a larger issue here where the hardware is not setup for automotive. Even if it was the speed of 320 messages a second is not enough!!. Even to get 1800 on ESP8266 I have to turn off Serial and traverse messages without any comparison. I am going to test using an ESP32 on MCP2515 next and see if it has the processing power to do 1300 messages a second, with basic transformation.
-
If anyone has the pinout for the GD32 chip I can use ChatgPT to write a firmware that transforms messages, anyone have it?
I have ordered CAN-FD modules that will wok with the ESP32 so swapping out and testing FD should work. If you guys want the code let me know, I can put on GITHUB. This all in one board form Longan labs or seeed studio I donât believe will work with automotive applications, esspecially with modern âchatty canbusâ cars.
Hello everyone,
im kind of new at CAN Sniffing and reverse Engeneering in Automotive things. For now I used a keystudio Canshield to sniff on different CAN in my car. I also had some MCP2515 CAN Bus Shields to send or change some signals on the CAN. Now I got my CANBed Dual to minimize the size of the CAN Sniffing Equipment. But any of my Computers are connecting with the Board. Neither my MacBook or my Windows Computer. Maybe someone can help me. Is it maybe broken?
After I connect the Board to my Computer, the blue continue double blinking. If I press the Boot Button while connecting the Board, nothing blinks. In both Cases the Cumputer wont connect with the board. It also will not show up in the device Manager.
Thanks for your help
