 ** The Demo **
 
 The demo shows how to use the ADC, PWM and SPI drivers using asynchronous
-APIs. The ADC samples two channels and modulates the PWM using the sample
-values. The sample data is also transmitted on the SPI port 1.

 By pressing the button located on the board the test procedure is activated
 with output on the serial port COM1 (USART1).
