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...
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...
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...
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...

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...
Can i use timer configured encoder with dma?
In RM0090 rev.17, ch.5.1.4 Voltage regulator for STM32F42xxx and STM32F43xxx, at several places uses ODSW bit name, while the actual bit is caled ODSWEN both in 5.5 Power control registers (STM32F42xxx and STM32F43xxx) and the CMSIS-mandated device h...
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...
Greetings everyone,I'm thinking of a setup where a STM32H7 series chip is witha 1.2V regulator powers the core directly bypassing the LDO (REG1)another regulator whose output can be switched between 3.3V or 1.8V (default 3.3V on power up) powering th...
