** 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.
APIs. The ADC samples two channels (temperature sensor and PC0) and modulates
the PWM using the sampled 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).
