Looking for STM32 SPI2 and SPI3 master-slave communication settings [Copy link]

I searched for several solutions online and tried them all, but they still don't work. Is it okay to set both SPI pins to output after push, and only set the master and slave in the SPI settings to be different, and then send and read data in the interrupt?

I suggest you take a look at the master-slave communication of N32G45. It is clearly written there and you can go and have a look.

Good to see

This problem has been solved, and the communication between SPI1 and SPI2 on the same block has been realized
