STM32F429: half-duplex SPI master with DMA stalls in the receive part

Hello,In my STM32F429 design I am using SP4 in master mode to read data from a slave with DMA in half-duplex mode. The setup is DMA2/Stream0 for RX and DMA2/Stream1 for TX, normal mode and no FIFO for both. Communication works without fail without DM...

STM32G030F gpio MODER seems readonly.

I'm bringing up my own STM32G030F board. I've gotten the "blinky" program to upload and run, but all attempts to change the moder of the GPIOs fail. At first I was using the proper macros but I've resorted to changing the MODER explicitly in my code,...

STM32G071CB unable to connect via SWD

Hi, I've been working with this device for a while.Today I started to try to write the option bytes in order to turn PF2 into a GPIO, which I did by writing an assembly file, compiling, and flashing via debug in Keil. I use a Segger J-Link as USB SWD...

Im looking for sample code for using a cheap, 433MHz RF transmitter and receiver

I would like to recreate this on an ST Nucleo Board under Zephyr.https://randomnerdtutorials.com/rf-433mhz-transmitter-receiver-module-with-arduino/Most of the code examples I can fine all run on Arduino and use libraries that don't seem to be availa...

Resolved! I can only change the gain of the SDADC once, not twice or more

I want to change the SDADC gain while the MCU STM32F373VBTx is running.That works, but only one time.First, at the initialization of the SDADC, the STM32 CubeMX set the predefined gain.Second, I set the gain by reading values from variables. That wor...

Here we go again with suffixed parts (STM32G474RET6U)

From the 'G4 DISCO UM2577:This board features a specific STM32 device version, which allows the operation of any bundled commercialstack/library available. This STM32 device shows a "U" marking option at the end of the standard part numberand is not ...

I would build a digital audio player with sd card using STM32F103C8

these are the following characteristics:- it should read data from SD card only (up to 32GB size)- SD card will be formatted FAT32- the root of SD card will contain folders only (named as album title/artist)- no subfolders will be allowed on SD card-...
