  @par Example description
  This example shows how to retarget the C library printf/getchar functions to the
  UART1. 
  This implementation output the printf message on the Hyperterminal using UART1 
  and keep waiting a character to be entered by the user.

  The UART1 is configured as follows:
    - BaudRate = 115200 baud  
    - Word Length = 8 Bits
    - One Stop Bit
    - No parity
    - Receive and transmit enabled
    - UART1 Clock disabled
 
  @par Directory contents

  - UART1\UART1_Printf\main.c           Main file containing the "main" function
  - UART1\UART1_Printf\stm8s_conf.h     Library Configuration file
  - UART1\UART1_Printf\stm8s_it.c       Interrupt routines source
  - UART1\UART1_Printf\stm8s_it.h       Interrupt routines declaration
  

  @par Hardware and Software environment

  - This example runs on STM8S High density and Low density devices and on STM8A
    High density devices.  
      
  - This example has been tested with STMicroelectronics STM8/128-EVAL evaluation 
    board and can be easily tailored to any other development board.

  - STM8/128-EVAL Set-up
     - Connect a null-modem female/female RS232 cable between the DB9 connector 
       CN13 and PC serial port.  

     - Hyperterminal configuration:
       - Word Length = 8 Bits
       - One Stop Bit
       - No parity
       - BaudRate = 115200 baud
       - flow control: None 


  @par How to use it ?

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

  - Copy all source files from this example folder to the template folder under
    Project\Template
  - Open your preferred toolchain 
  - Rebuild all files and load your image into target memory
  - Run the example
  
  @note
  - High-Density STM8A devices are the STM8AF52xx STM8AF6269/8x/Ax,
    STM8AF51xx, and STM8AF6169/7x/8x/9x/Ax microcontrollers where the Flash memory
    density ranges between 32 to 128 Kbytes
  - Medium-Density STM8A devices are the STM8AF622x/4x, STM8AF6266/68,
    STM8AF612x/4x, and STM8AF6166/68 microcontrollers where the Flash memory 
    density ranges between 8 to 32 Kbytes
  - High-Density STM8S devices are the STM8S207xx, STM8S007 and STM8S208xx microcontrollers
    where the Flash memory density ranges between 32 to 128 Kbytes.
  - Medium-Density STM8S devices are the STM8S105x and STM8S005 microcontrollers
    where the Flash memory density ranges between 16 to 32-Kbytes.
  - Low-Density STM8S devices are the STM8S103xx, STM8S003, STM8S001 and STM8S903xx microcontrollers
    where the Flash density is 8 Kbytes.
