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...
STM32H7 and QUADSPI external flash reading problem - One byte every two is skipped
Dear all,I am trying to communicate to a flash memory using the STM32H750 micro and its QUADSPI interface. For this I use the STM32H750B-DK Discovery board which provides a dual external flashmemory (MT25QL512). In my first example I am just trying t...
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...
STM32-F401RE About clock Setting in various system_stm32f4xx.c files
Hello EverybodyI started using Nucleo-F401RE (MB1136 C-04) a few months ago and I am trying to understand how work the SystemInit() function and the clock setting.As IDE, I use SystemWorkbench/AC6.When I start a new project using HAL or LL drivers, t...

ST-MCU-FINDER-PC v3.1.0 - STM32G03x not covered?
Hi,Just downloaded the ST-MCU-FINDER-PC to compare some STM32G03x MCUs and have not found them in the app.Is there any alternative to easily compare two MCUs? Years ago I used to use xls sheet but I cannot find it now...
