I speculate that during the encoder's response time, the SPI clk continued to generate, leading to this issue. I then measured the encoder's response time to commands, which was approximately 2.9us, equivalent to 2.9us/400ns=7.25bits, which does not match the actual situation. I would like to ask about the causes of this situation and possible solutions?[/quote] Can you capture the waveforms for the request/response like the examples below? Does the SW complain about a CRC error?
