I am trying to communicate STM32NUCLEOF072RB with STM32NUCLEOF429ZI using CAN Rx and Tx. I went through below YouTube video in which they directly connect RX and Tx but i couldn't able to do this. so kindly let me know is it possible that we can use CAN RX of one board directly connect to Rx of another board and similar Tx without using any transceiver module and 12ohm resistor?
Keil implements a simple CAN network without transceiver, likely suitable for quick test, with boards on a bench. ie low speed, close together, good grounds
