Hello for my student project, i need to communicate with an RF chip using SPI. I used the polling method, mentioned in the cookbook examples to build my code. Unfortunately, this is not efficient and i am getting wrong results in continuous run. Is there any examples available on SPI Interrupt non-SDK. I enabled the IER in SPI for RDIE and TDIE, but is a little bit confused regarding the definition of the handler, so i used only RDIE, but it was not working properly. I need to read 2 bytes in the recieve for getting the result. Attached code below for reference. *Sorry its incomplete due to some modifications. Kindly help me.
