Hexiwear / Mbed OS Hexi_Gyro_Example

Simple gyroscope program example for Hexiwear featuring UART

Dependencies:   FXAS21002

Fork of Hexi_gyro_app by Mac Lobdell

This project demonstrates the use of the FXAS21002CQ Gyroscope sensor embedded in hexiwear

Open a Hyperterminal tool on your computer and connect it to the "mbed Serial port (COMxx)" with Baud rate "9600bps"

Compile the project and copy the binary "Hexi_Gyro_Example_HEXIWEAR.bin" in the DAP-LINK drive from your computer file explorer Press the K64F-RESET button on the docking station to start the program on your board

Every 1s the value of the Gyroscope for the Axis Roll, Pitch and Yaw plus their RMS value will be displayed in the Hyperterminal window and the LED will blink Green
