+** ChibiOS/HAL - SPI driver demo for NRF51x22. **
+*****************************************************************************
+
+** TARGET **
+
+The demo runs on an Waveshare BLE400 board.
+
+** The Demo **
+
+The application demonstrates the use of the NRF51x22 SPI driver.
+
+** Board Setup **
+
+- Connect MOSI (P0.24) and MISO (P0.23) together for SPI loop-back.
+
+** 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.
