I am planning to use ADC with 16 bits achieved using oversampling in STM32U5.But on Datasheet there is no data wrt to ADC oversampling.Can somebody help me with data regarding ENOB, EL,ED when ADC is oversampled. Datasheet : DS13737Datasheet - STM32U...
Hi.I am having some issues trying to use the EXTI module, to implement interruption routines associated to ports.The problem is related to the behavior of STM32 microcontrollers with ports interruptions. In most microcontrollers (i.e. Texas Instrumen...
I need to be able to read an external sensor whose status should be interpreted as received communication. This will either be an analog signal that needs to be processed via an ADC or an external I2C ADC - the result of which needs to be further pro...
I'm looking to use a ITS4200S-ME-P relay to switch a high voltage signal and would like to control that via a UART. Per the datasheet this relay, "can be switched on and off with standard logic ground related logic signal at pin IN."
SetupSTM32G491KEADC1 Input Channel 3 using Pin PA2Vdd = 3VRC-Filter at the ADC input with R = 33 Ohm, C = 330 pFObservationWhen measuring the voltage at the ADC input with an oscilloscope, we see the voltage drop caused by switching the input signal ...
HiI'm using STM32H750VBT6 with W25Q32 QSPI external flash memory from Winbond and I'm using Keil Microvision IDE with ARM_CC Compiler.I'm trying to execute my whole project from the QSPI flash directly (which is called XIP). I know that I have to con...
Hi,I'm working on the FW for STM32H725VGT6 MCU and something strange is happening.I've created a simple project with cubeIDE (with usart2 and a GPIO to toggle) and the code created and compiled with no issues. After uploading the code with debug mod...
Hello. I am working with internal Flash memory on STM32F407, I have 4 functions as described below:void FLASH_save_CP_serial(uint32_t serial_number) { taskENTER_CRITICAL(); uint32_t write_test = 12345; FLASH_EraseInitTypeDef Eras...
Hi All,I am using STM32F301k8 for my remote project. I am using HSI clock source, I am enable one i/o interrupt and using UART1. for sleep i am using STOP mode by following functions.HAL_UART_DeInit(&huart1); __HAL_RCC_USART1_CLK_DISABLE();HAL_Susp...
