hello:
At present, there is a demand to be realized through the CAN bus. We use the standard can. We hope to make a switch by judging whether the can signal from the OBD port comes out. We can sample the level on can-h and can-l through ADC, or we must add a transceiver to interpret the message; Can the level on the CAN bus be sampled through the ADC
我现在想通过MCU上的ADC对CAN总线上的电平进行采样，按照CAN通讯协议，由于没有收发器，会一直报错；但是我不需要实现通信；我只需要判断Can总线的电平变化；OBD口的CAN我是可以控制的；想问一下逻辑可以实现吗
