How to init SPI properly

Tommino · ‎2022-07-21

Hi,

I am trying to init SPI1 (to just receive data qwith MISO) on nucleo G474RE without using HAL libraries.

Can you help me to assess why my code does not work ?

I can't see the clock eventhough SPI1 is enabled

void SPI1_init(){
	RCC-> APB2ENR|=(1 AHB2ENR |= (1MODER &= ~(1 AFR[0] |= (1 AFR[0] |= (1 AFR[0] |= (1 CR1 |= (1 CR1 |= (1 CR1 |= (1 CR2 |=(1CR2 |= (1CR1|= (1CR1|= (1CR1&= ~(1

@Tommino "How is this prevented?"

There'll be a status bit that tells you when a transfer has completed.

On this chip, you also have read & write FIFOs

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
