Need help in making USART2 work on STM32F303RE

Hi, I am doing a MOOC for learning STM32 programming, in the UART topic, we are supposed to implement UART. The course follows STM32F4 but I have an STM32F303RE and I tried to adapt it to my board but it is still not showing anything on the serial mo...

So far 2 boards have died and I am uncertain how they failed, is there a chance they could be fixed through software?

I was using a Nucleo F746zg to develop firmware and in the middle of testing after consistently functioning for over an hour, it stopped communicating with the st link and started showing an overcurrent error. After further testing, the voltage regul...

Stm32f4 DISCOVERY/ Trying to change slave mode and trigger source with REGISTERS for 3 phase shifted PWM.

I read datasheet stm32f407vgt6 datasheet TIMx slave mode control register (TIMx_SMCR) configured as datasheet said but doesnt works. I shared my mainC I am beginner in embedded software and register programming. also ı Shared my timer configs cubeIDE...

Im facing CAN transmit error,HAL_CAN_ERROR_TX_TERR0 (0x00001000U) /*!< TxMailbox 0 transmit failure due to transmit error */. Can anyone guide me how to resolve this or what is the reason for this error. Im using a NUCLEO-F767ZI board.

How to: 32F4 Cortex-M4(F) Lazy Stacking and Context Switching

There must be a function to save the FPU context of the 32F4 but after an hour searching all I see is 11 years of people asking for clarification on how to do this, and nice looking technical papers none of which list more than a couple of lines of A...

Nucleo-G474RE I2C Debug Problems

Hello everyone, I am trying to make an I2C communication with the Nucleo G474RE, however I am having problems at the time of Debugging. This is causing that the SCL stops working on my board.I use the I2C1 Pin 14 (PA14) and Pin 13 (PA13) in the initi...

I get the wrong status value when I read back the SPI data.

Hi, i am trying to integrate SD card with SPI over STM32H750VBT6 evaluation board.SD card mounted but i can't create file,I can't write into file.I checked hardware connection and code but nothing has worked for me.Any one can help to solve?
