SPI slave mode. Getting Started.

I'm in the early stages of a project involving SPI. I need to send data to an stm32f303, from an rPi.I also need to detect, from the rPi, a GPIO based interrupt to then go read from the stm32.rPi is master, stm32 is slave.Can anyone recommend a helpf...

Resolved! Non-blocking SDIO SD Access - SDIO Timeout

I've been working on making my SD SDIO card access non blocking. My implementation is a derivative from the standard ST SDIO SD driver (stm324xg_eval_sdio_sd).I'm using Protothreads (basically a state machine) to make the SD SDIO calls non-blocking a...

STM32F750Z8 and flash loader

Hello everyone,I've just develop my board with this MCU and a QSPI Flash from Micron (N25Q128).The connections suggested by the Cube are:CS -> PB6CLK -> PB2D0 -> PF8D1 -> PF9D2 -> PE2D3 -> PA1Checked them and they are phisically good.I'm using IAR so...

I am having trouble with timers on STM32F1xx series specifically. I can get PWM to work but no matter how the TIM_TimeBaseInitTypeDef structure is defined, the frequency is 1.1KHz. It appears that the prescaler is divide by 64k. What's happening?

SYS_RC TIMER_setup(void){   TIM_TimeBaseInitTypeDef      TIMER_BaseInitStruct;   TIM_OCInitTypeDef         TIMER_OCInitStruct = {0, };   GPIO_InitTypeDef         GPIO_InitStruct;   RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB, ENABLE);   RCC_APB1Perip...
