I've got some code working from an example for USART RX DMA Circular. I'm to the point where I can receive the UART data but I need to now use a write to a protected (by a binary semaphore) circular buffer from the interrupt context HAL_UARTEx_RxEve...
Hi,I've seen that in many stm32 tutorials (such as blinking LED and uart tutorials) they make use of a "while (1) " loop located in main.c: But, in the main.c generated by cubeMX for my stm32l496ag board i have only the following single while loop, ...

We have STM32F401VET6 in our product development. Currently, our project (makefile) compiles and stores application binary in STM MCU internal flash. We would like to store three other binary/hex files to the STM MCU internal flash as part of the bui...
Hi guys I have set up my STM32 as an SPI full duplex slave device. All SPI communication happens through DMA. The Master device is a Beaglebone Black communicating over linux spidev driver. The problem I am facing now is if the master sends multiple ...
Hello!As the title says, I haven't managed to get the printf function to work on my STM32H7 MCU. I am using the Nucleo-H745ZI-Q with STM32Cube MX and Keil. Here is the code I'm using:#include "stdio.h" /* USER CODE BEGIN 0 */ #ifdef __GNUC__ #defin...
I'm having a brain fart and can't figure this out. I'm porting an existing project from the STM32F205 series to the STM32L496 series. So I replaced "system_stmf2xx.c" with "system_stml4xx.c" in my project workspace, but my compiler (IAR) isn't pickin...
After resetting, the output of PA9 and PA10 of the STM32G030K8 microcontroller is high. These pins are not initialized, according to the datasheet after reset they should have the function of an analog input. Once configured, they function normally a...
Hallo,I'm using a STM32H745, that shall access an external NOR flash with the timing recommended by ST at the reference manual RM0399 on page 875. I did exactly reproduce this timing setting, but no access will be generated on the FMC pins.When I ch...
HELLO ive created a project in cubemx v4.22. later i changed to new version i mean i downloaded the v 4.24.0 if i add iwdt then i get the project it doesnt compile , igot this error compiling system_stm32f1xx.c...linking...ROVER_LORA\ROVER_LORA.axf: ...
