This is a PWM based LED fading example using libopencm3.
|
||||
|
||||
It's intended for the ST STM32-based MB525 eval board (see
|
||||
http://www.st.com/stonline/products/literature/um/13472.htm for details).
|
||||
It should blink the LED on the board.

to USART1 and afterwards copied by DMA to another memory location. To check

if the transfer was successful we send the destination string also out to

USART1.

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).
