+*****************************************************************************

+** ChibiOS/HAL - ADC driver demo for NRF51x22.                             **

+*****************************************************************************

+

+** TARGET **

+

+The demo runs on an Waveshare BLE400 board.

+

+** The Demo **

+

+The application demonstrates the use of the NRF51x22 ADC driver.

+

+** Board Setup **

+

+Connect P0.02 (SMBA) to an analog voltage between 0 - VDD.

+

+** Build Procedure **

+

+The demo has been tested using the free Codesourcery GCC-based toolchain

+and YAGARTO.

+Just modify the TRGT line in the makefile in order to use different GCC ports.
