Hexiwear
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
