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...
Resolved! Problems with programming STM32 mcu with stm32cubeIDE (failed to erase memory)
Hello,I am using STM32G030F6P6 in one of my projects. I am using STM32 CubeMx as my IDE.In the datasheet I can see that it has 64KB of flash. However IDE perceives this as 32KB and I can not upload my code. This is what I read from the console. Does...
What is the maximum main frequency of the STM32H7 devices, and if this frequency can be output by any of the devices pin?
What is the maximum main frequency of the STM32H7 devices, and if this frequency can be output by any of the device's pin and if this frequency can be input by any pin of the device. By the way, the project we are working on need the frequency is th...
Resolved! Is there any way to reset only M7 just or M4 just core through IWDG or WWDG without issue in STM32H745
STM32H745 IWDG if it reaches downcounter 0x0000, it mentions that system reset is generated.Is there any way to reset only M7 just or M4 just core.Also Errata Mentions that AXI domain is locked when watchdog reset is limited to CPU1 or CPU2 only. Is...
