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.
