Example Description

This example describes how to retarget the standard input and output function to the UART1.

In this example, Main clock is configured at 24MHz.

The code to implement the standard input and output retarget function is in \Utilities\Common\Retarget_uart1.c.

The UART1 is configured as follow:

  • BaudRate: 115200
  • Word Length: 8
Directory contents
  • UART/UART_Printf/UART_Printf.uvprojx MDK5 project file
  • UART/UART_Printf/UART_Printf.uvoptx MDK5 project options file
  • UART/UART_Printf/JLinkSettings.ini Jlink settings file
  • UART/UART_Printf/main.c Main program
Hardware and Software environment
  • Hardware environment
    • The chip pins are connected as follows:
      • UART1 (PD5, PD6) is connected to PC serial port
How to use it ?

In order to make the program work, you must do the following :

  • Open UART_Printf.uvprojx from this example folder by Keil MDK5
  • Rebuild all files and load your image into target memory
  • Run the example
