The role of AVDD on Nucleo-L476RG

Hi people!I am currently using a Nucleo-L476RG connected to an analog sensor. On the datasheet of the mcu, in the ADC section, I can read "One external reference pin is available on some package, allowing the input voltage range to be independent fro...

FDCAN module not working on STM32G0B1

In any mode of FDCAN, receiver doesnot seem to be working. My project is attached..

prinf and scanf will not work in c++ .please share with complete solution cout and cin usage in c++

Are there available math libraries in assembly for the STM32G031 type processors?

I'm using an STM32G031F8 for a job right now. I'm coding in GCC assembly, no OS. This thing doesn't even have a hardware divide (much less FPU). I pulled out some old routines from NXP ARM7 chips for doing unsigned div 32 bit by 32 bit and 32 bit ...

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...
