&par Example Description

The program shows how to send data by using USART, in this case,
USART1 sends data to upper computer. You can check the data in a Serial Port Utility.

  - USART1 configured as follow:
  - BaudRate    = 115200
  - Word Length = USART_WordLength_8b
  - Stop Bit    = USART_StopBits_1
  - Parity      = USART_Parity_No
  - Hardware flow control disabled (RTS and CTS signals)
  - Transmit enabled

&par Directory contents

  - USART/USART_Printf/Source/apm32f402_403_int.c     Interrupt handlers
  - USART/USART_Printf/Source/main.c              Main program

&par IDE environment

  - MDK-ARM V5.40
  - EWARM V8.50.5.26295
  - ECLIPSE-EMB V4.24.0

&par Hardware and Software environment

  - This example runs on APM32F403 TINY Devices.
