I just want to connect STM32H753VIT6 with FT4222HQ-D using SPI.
STM32 is a master, and FT4222 is a slave.
i want to set that STM32 send a data first by polling and then receive a char data by interrupt.
when i receive a data, i wanna have no buffer, just using receive date register(RXDR) and put that register's value into a variable.
then i use that variable for my taste.
but Problem is
now i'm using if(SPI2->SR & SPI_FLAG_RXWNE). but it seems not working.
when it runs, TransmitReceive works but Receive_IT dosent work.
and so many problem is on me.
please give me a advice
many thanks!
