I have generated MDK-ARM project from the USART_3_Receive_Send example from stm32 mat target example, I have successfully compiled all and burned to stm32f103 board, when connected to terminal it finds, it is sending unknown chartacters to terminalI ...

Resolved! Problem about APB1 Clock Configuration for Timer

Hi Everyone ! I have a problem for calculating timer for 1ms. I attached configuration for clock and timer.As I understand Timer2 uses APB1 Clock Bus but for timer it will be APB1x2 if APB1 prescaler is not " 1 "So when I use Prescaler 59999 for 60Mh...

interrupt latency with 2 two Identical board

Hi, I am using two Identical board, both board installed with a STM32F733ZE, and both have the same program loaded.The program is very simple where if an interrupt from PG0, will reset the PWM counter of TIM8. provided with the same interrupt source,...

About STM32L4 ADC and SD interface problem

I have nucleo-64 STM32L476 board. I have initialised ADC. I am able to read all the three channels ( that I configured in cube Mx) correctly using DMA.Then I added SD interface. I was able to read and write in the SD Card as well. But as soon as I in...

What happens when an Exception occurs in Exception Handler I'm working with the STM32H755ZI and gcc.

Dear people,I do not understand the following behavior of the STM32H755ZI:I implemented a stack test by configuring a safety zone with MPU. When the stack overflows, the MemManage Handler is called. So far so good.In this MemManage Handler I only sav...

SPI mode change

Hi all,I'm working on Full-duplex SPI with Cube-MX and HAL.I'm going to dynamically set the SPI mode(Master/ Slave). So, init the SPI according to the input pin (input pin=1 for master and 0 for slave). The master MCU Transmit and the slave receive c...
