*****************************************************************************
** ChibiOS/RT port for ARM-Cortex-M0 WvShare BLE400 (nRF51822). **
*****************************************************************************
** TARGET **
The demo runs on an WvShare BLE400 board. This board is powered by a Nordic
Semiconductor nRF51822 processor which is an ARM Cortex-M0 with bluetooth radio
hardware. This board can be easily found on chinese websites.
** The Demo **
This demo will print the standard TestThread output and blink all LEDs in a
sequential.
** Build Procedure **
The demo has been tested using the freely available GCC ARM Embedded toolchain.
