STM32L412 One-pulse Timer not resetting at update event

Hi all,I am trying to get a single pulse out of TIM1, triggered by a rising edge on a Pin.I got it almost working, but the problem is that after the counter reached ARR value, the output channel is reset...I use PWM mode and the complementary output ...

Hi, I need to develop a pulse (GPIO) counter with one STM32L031K6 microcomputer. My requirement is to have the best accuracy on 1 second counting at the range of 10 to 20 KHz. Do you know how to proceed ? Any help will be appreciated.

UART Interrupt callback calling only when running in debugging mode using Stlink-V2 Debugger

Hi, I am working on STM303CBT6 MCU custom design board, USART3 Interrupt callback working fine when program is running in debugging mode.If program running in Normal mode without debugger, USART3 Callback function not calling.Note, MCU BOOT0 pin is c...

Setting up UART 1 on B-L475E-IOT01a using bare metal (Newbie)

I can see an output in my serial monitor if i am using CubeMX and CubeIDE but with baremetal in Keil, I dont understand why i am not seeing any . I have a B-l475E-IOT01a board with me, and from the schematic I can see both UART1_TX and UART1_RX conne...

UART-1 working code reads NULL

Hi clive I have interfaced UART DATA device(sender) and NUCLEOF401RE(receiver) I have set the proper BAUD RATE 115200I am using UART-1 to receive dataI generated the code in the IDE and first tested for transmit functionality and it works fineI took ...

STM32F4 wake up from stop mode with UART

I am using STM32F407VG MCU (STM32F4 Discovery board) and I want my MCU to wake-up from STOP mode when it receives a message from UART. I had to adjust some things manually because the STM32CubeMX is unable to set UART Rx pin as an GPIO interrupt pin ...
