Thank you for your response,My code works partialy.If I transmit the same data in a loop from the Master using this code: snprintf((char *)data_tx.msg, MSG_SIZE, "IdFrame=0"); then I the same checksum on the Slave.However, if I add a parameter, so th...

Hello, It's finnaly some experimental work and ChatGPT who resolve the problemlook bellow at this response that ChatGPT gave me.Apparently, the circular mode is perfect for continous data transfer

I added the code for configuring the NSS on the Master, and did not change anything on the Slave, but this still did not resolve the problem. I want to add some additional information: when I run the slave, I receive the correct data for the first it...

Thank you for responding to me,I already address the issue with manual delays. I removed the manual delays.I also an Hardware NSS Signal: Output Signal for the Master and Input Signal for the Slave. But this also did not resolve the problem. I use a...
