------------------------------------------------------------------------------ README ------------------------------------------------------------------------------ This example program sends some characters on USART3 on the ST STM32-based Olimex STM32-H103 eval board (see http://olimex.com/dev/stm32-h103.html for details). The terminal settings for the receiving device/PC are 38400 8n1. The sending is done in a blocking way in the code, see the usart_irq example for a more elaborate USART example.
