The demo shows how to use the ADC, PWM and SPI drivers using asynchronous
APIs. The ADC samples two channels (temperature sensor and PC0) and modulates
the PWM using the sampled values. The sample data is also transmitted using
the SPI port 1.
the SPI port 2 (NSS=PB12, SCK=PB13, MISO=PB14, MOSI=PB15).
By pressing the button located on the board the test procedure is activated
with output on the serial port COM1 (USART1).

(backported to 2.2.8).
- FIX: Fixed broken TIM8 support in STM32 PWM driver (bug 3418620).
- FIX: Fixed halconf.h file corrupted in some STM32 demos (bug 3418626).
- NEW: Added demo for the ST STM32F4-Discovery kit.
- NEW: STM32F4xx ADC driver implementation.
TODO: Backport the new solutions implemented in this ADC driver to the
STM32L1xx ADC driver.
