I am trying to establish Serial communication between Arduino and Nucleo-f411re,I have connected the TX of Arduino to PA10 (UART 1 RX) of the Nucleo, I have tried using a voltage divider also but t did not workNucleo code#include "stm32f4xx.h" ...

“and ground?�?Yes, I have connected both ground and 3v3 together. “Is PA10 (UART 1 RX) of the Nucleo shared with any other hardware on the Nucleo; eg, the ST-LINK�?no, the USART 2 Is shared with ST LINK, USART 1 is not shared with anything.“ Before b...

sorry for the lack of details,i am using Nucleo-F411RE, and the LCD is LCD2004A.the wiring is * PC0-PC7 for LCD D0-D7, respectively.* PB5 for LCD R/S* PB6 for LCD R/W* PB7 for LCD ENThe delay works for blinky but It counts 2.65 seconds rather than 1 ...

UART communication between Arduino and Nucleo-F411RE

I am trying to print the word hello on the LCD screen, but it is not working and I don't know why, although I am copying the code from a book for Nucleo board. i know it is a silly question, but I have just started :)
