When I was looking up the documentation about CAN's self-reception issue, I saw this sentence: [size=5][color=#ff0000]When a self-reception request is generated, if the acceptance filter is set to the...
I would like to ask the experts a question: D1, D2, D3, D4 of PT2272 are connected to P1.0, P1.1, P1.2 and P1.3 of AT89C2051 (high level is valid). When D1 is high level, why is P1.0 unresponsive? But...
