Topic: Can not receive CAN DATA from Arduino UNO with MCP2515 Module. (Read 34613 times) previous topic - next topic


I use 2 sets of uno + mcp2515 + tja1050, and the transmission is normal. So, the hardware is good. However, one set did not respond to obd2.


I tested successfully. I know the problem is there. 1. The oscillation frequency of MCP2515 should be set correctly. Mine is 8Mz, 2 TJA1050's resistance is 120 ohms, and JUMP should be plugged in.
