Independent watchdog timer makes my MCU unstable

Hello,Here is my source code:  void WatchDog(void){   NVIC_InitTypeDef nvicStructure; NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);   nvicStructure.NVIC_IRQChannel = WWDG_IRQn; nvicStructure.NVIC_IRQChannelPreemptionPriority = 1; nvicSt...

STM32 L522C . I want to get chip to sleep mode and wake it up by time interrupt of 32KHz clock . How do I?

I'm about to start embedded programming and have an STM32f103C8T6 ARM-Coretex-M3 board to get started with. I'm also a C++ programmer and want to use that language to program a project to blink the LED of that board as my first embedded task.

Hi all, Apart from the board and two machines (Windows and Linux) I have also an MB-102 breadboard and a bunch of cables in hands. Firstly I wanted to make use of this tutorial for the task above but it's dealing with NUCLEO-L476RG that I lack for th...

DMA UART TX single transfer

Hello, I have an stm32F103, I would like to start using DMA to transfer data from memory to TX pin, in circular mode it works fine but when I switch to normal mode it works only once, I cannot use the debug function since I'm not using a ST-Link, so ...

How does HAL_UART_Transmit_IT() triggered Interrupt handler HAL_UART_IRQHandler() for data sending?

HAL_StatusTypeDef HAL_UART_Transmit_IT(UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Size){ /* Check that a Tx process is not already ongoing */ if (huart->gState == HAL_UART_STATE_READY) {  if ((pData == NULL) || (Size == 0U))  {   return HAL_...

How to identify a genuine STM32 MCU and where to purchase genuine STM32 MCU ?

I am new to STM32, recently came across the compatibility of none genuine STM32 MCU issues.For example, I found the STM32F103C8T6 chip link at HERE, which one is genuine STM32 MCU in this case ?Secondly, where can I find a trusted vendors that supply...

STM32 Timer auto-reload preload

The conditions to reproduce: Here is my real life example that I would like to solve:I am developing an application on an stm32f411RET which needs to dynamically change the period of two PWM's.The two PWM's need to be synced and have exactly the sam...
