I couldn't find the SPI response message in the sigmastudio for sharc interface document, and the upper computer cannot determine whether the instruction was successfully sent. I want to use the pfSPIRxIsrCallBack function as a response, but this callback function cannot be triggered in CCES. Here is a screenshot of my code. I registered the callback function on line 85.
May I ask how to use callback functions? Will any SPI command enter a callback?
