+This example program sends some characters on USART1.
+Afterwards it connects to an STTS75 sensor (ST LM75 compatible)
+at adress A0/1/2=0 and sets reverse polarity, 26 degree Tos and Thyst.
+
+It reads out the temperature and submits the temperature over USART1 in
+binary format (ASCII 0/1).
+
+The terminal settings for the receiving device/PC are 115200 8n1.

+This is small LED blinking example program using libopencm3.
+
+It's intended for the ST STM32-based Olimex STM32-H103 eval board (see
+http://olimex.com/dev/stm32-h103.html for details). It should blink
+the LED on the board.

+
+It's intended for the ST STM32-based Olimex STM32-H103 eval board (see
+http://olimex.com/dev/stm32-h103.html for details). It should blink
+the LED on the board.

+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.
