UART behavior on reception error, flags set, e.g. PE, NE, FE
Alright, I am searching the STM32L4 reference manual (RM0351), and as far as I can see, there is no description of how the UART is expected to behave when various "reception error" flags are set. In my case, I am observing NE when resetting a modem, ...
Caprure compare Interrupt
I try to generete interrupt when CNT register reach any value. But It generete when I enabled to interrupt EGR bit is always zero. when I try to change accept first bit not effected.It is configuration capture = TIM_GetCapture2(ExternalOSCTimer); TI...
STM32F407 RTC sporadically showing future time
Most of the future time occurs around 12:00 in the morning, here are the instances captured on the device:1. The actual time is: 2023-01-11 11:59:55, the STM32F407 RTC time is: 2023-01-12 12:00:002. The actual time is: 2022-12-31 11:59:58, the STM32F...
Resolved! Reconfigure the synchronized timers
Hi, I'm using STM32F407 development board. I synchronized TIM2 as master and TIM5 as slave. Timer initialization functions:void TIM2Config (void) { // 1. Enable the TIM2 clock RCC->APB1ENR |= RCC_APB1ENR_TIM2EN; // 2. Set clock coeff. as 2, ena...
STM32F1:How to change the I2C address when program running
I'm trying to change the I2C address by using HAL_Deinit & HAL_Init, but it doesn't seem to work. The function below is what I wrote myself to change the address：If I try to change the address,the register shows that the I2C address has been changed,...
STM32h7 Multichannel ADC DMA is not working.
Hi,I am try to read four ADC Channels of ADC3 using DMA method. But I did not get the data.Below is my programmingstatic void MX_ADC3_Init(void){ ADC_ChannelConfTypeDef sConfig = {0}; hadc3.Instance = ADC3; hadc3.Init.Resolution = ADC_RESOLUTION_16B;...
UART transmit works succesfully but reciever don't
The device I am using is F303K8T6.I am trying to learn. I have no problem with transmitting.But when it comes to receive data it don't works. Interrupt not rises.But when I connect tx pin to rx pin it works well. Interrput rised. The code and concern...
STM32 H745. Is it possible to trigger a dma transfer from memory to SPI on rising/falling edge of pwm generated from a timer?
Hello, I'm having trouble reading from external ADC which needs a maximum time of 10ns from the falling edge of command (I'm giving it from a TIM4 PWM mode 1, 300ns active, 100kHz frequency). I'm using TIM3 as a slave timer from TIM4, one shot and TI...
