*****************************************************************************
** ChibiOS/RT HAL - 1-Wire driver demo for STM32F0xx. **
*****************************************************************************
** TARGET **
The demo will on an STMicroelectronics STM32F0(308)-Discovery board.
** The Demo **
The application demonstrates the use of the STM32F0xx 1-Wire driver.
** Board Setup **
To use demo you have to power your 1-wire device from 5V bus on board
and connect DQ line to PB0 pin. Do not forget about external pullup
resistor to 5V (4k7 recommended).
** 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:
