Hello, I am writing an application for STM32H7. I need to clear serial terminal the screen before showing the new lines on the terminal. Can anyone please help? Thank you in advance. Vouria

Program stops in WWDG_IRQHandler() infinite loop after enabling ADC interrupts.

/* enable ADC interrupts */ HAL_NVIC_SetPriority(ADC1_IRQn, 0x05, 0x00); HAL_NVIC_EnableIRQ(ADC1_IRQn);I have an analog input connected to the ADC1 on the SensorTile evaluation board and would like to run the ADC in interrupt mode. I mostly follow th...

Hardword: STM32F0_DiscoveryDevelop_Kit: Keil5.30+STM32CubeMXI define the printf function in main.c as below:#include "stdio.h"#ifdef __GNUC__ #define PUTCHAR_PROTOTYPE int __io_putchar (int ch)#else #define PUTCHAR_PROTOTYPE int fputc(int ch,FILE *f)...

I have a B-L475E-IOT01A. I am having issues reading value into the ADC. My values change but only slightly. I am testing it a POT from 0 to 3.3V as verfied by an volt meter.

 I seem to have things configured correctly. This is the bulk of my code:  while (1)  {    /* USER CODE END WHILE */    /* USER CODE BEGIN 3 */    HAL_ADC_Start(&hadc1);    while (HAL_ADC_PollForConversion(&hadc1, HAL_MAX_DELAY) != HAL_OK);        ad...

Functions in while loop are not working when ADC DMA conversion

Hello,I successfully convert analog signals in to digital with ADC DMA mode. But when ADC is converting the analog signals, the functions in while loop are not working. It looks like that while loop is not operating. Do you have suggestions about the...

Updated time of RTC is not being read

I am running RTC for stm32h753. If I read the time of RTC, I do not get updated value as shown in below example. I am using LSE 32.768Khz. As it can be seen that 00:08:10  is being read repeatedly and then 00:08:15. if I compare overall time, it is ...

how to use ADC in discontinuous mode without HAL?

I am trying to use the ADC without using HAL (except for in the setup) on a STM32F031K6, using cubeIDE. Im using the ADC in discontinuous mode - as far as I can tell, the sequence of events should be  - ADC is setup, then enabled with ADEN - ADC star...

How can I capture external signal? I want an interruption function call on each risign signal edge.
