SPI slave receive interrupt
Posted: Tue Jan 09, 2024 8:44 am
Hello,
We are using ESP32-C3 as SPI slave and configured in receive interrupt mode and stm32 board as SPI Master.
So, When Master is sending any data on SPI the same data is sending back from ESP32-C3 (slave) to the master(STM32). Master is able to receive that data back.
The problem is we are unable to locate the routine in which the ESP32-C3 is sending back the received data to master, and we are unable to use serial(uart) print in the SPI handler as we don't have debug facility. Please help me to find out the routine which Transmitting the data on SPI to master.
Thanks & Regards,
D.Vineetha.
