BaudRate not correct while using USART on NUCLEO-L053R8

Posted on August 23, 2017 at 00:22I'm using NUCLEO-L053R8  for USART communication. below is the configuration of usart2, which connects to the st-link as a COM to PC.static void MX_USART2_UART_Init(void){huart2.Instance = USART2; huart2.Init.BaudRa...

STLINK-V3 Mini UART doesn work from the edge connector

Hi EveryOne!I use a brand new ST-Link V3 Mini shield and would like to use its Virtual Com-Port feature with connection via its Edge connector. SWD works well but UART doesn't at all.I use pin 1 & pin 11 for connection to UART but no result. PS. If I...

What uart port connects to the modem on the B-L462E-CELL1 board?

Using an Aliexpress STM32G070RBT6 board, no ST-Link

I bought a $4 Aliexpress STM32G070RBT6 board. I have a program that uses various UARTs, timers, pins, etc. The CPU should be unprogrammed since the board is new. For all I know, the CPU may be counterfeit, but usually these sort of Chinese boards wor...

I have some problem with stm32h723zg uart

I was working with stm32h723zg uart3 pin. I was using micro usb pin with stlink for uart and It works fine but I relise I have to use 3.3V power for pwr consumption test with stlink-v3pwr so I set jp2 with no jumper, and set on jp1 which it will set ...

I am new to STMicro products. How do I connect an STM32l010F4 to an ST-link programmer? Is there a document that explicitly states which STM32l010F4 pin connects to which ST-link pin?

I do not have room on my board for a large connector, so I need to create a custom cable. The STM32l010F4 boots via USART, yet I cannot find anything in the ST-link docs that says "connect this pin to usart Tx, and this one to the usart rx, etc.If so...

STM32F4 DISCOVERY Board has noisy USART2 when board is powered by external source and USB ST-Link is disconnected.

I have an STM32F4 Discovery board with a USB->Serial converter connected to pins PA2 (TX) and PA3 (RX). I used CubeMX to configure usart2. My test code successfully sends data over usart2 when I power the discovery board as usual over USB.However whe...
