6D Orientation Demo Application based on sensor expansion board X-NUCLEO-IKS01A2
Main function is to show how to use sensor expansion board to find out the 6D orientation and send data using UART to a connected PC or Desktop and display it on terminal applications like TeraTerm.
After connection has been established:
- the user can rotate the board to change the 6D orientation and then view the data using an hyper terminal.
- the user button can be used to display the current 6D orientation.
