*****************************************************************************
** ChibiOS/RT HAL - ADC driver demo for STM32F37x. **
*****************************************************************************
** TARGET **
The demo runs on an STMicroelectronics STM32373C-EVAL board.
** The Demo **
The application demonstrates the use of the STM32F37x ADC/SDADC driver.
** Board Setup **
None.
** 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.
** Notes **
Some files used by the demo are not part of ChibiOS/RT but are copyright of
ST Microelectronics and are licensed under a different license.
Also note that not all the files present in the ST library are distributed
with ChibiOS/RT, you can find the whole library on the ST web site:
