5.7.1
This is the main application of the ZSTAR3 project. Only this application can provide the ZSTAR3 USB
protocol (extended STAR protocol) commands and run all the functions and features of the ZSTAR3 demo.
When CDC application is active LED3 blinks are depending on USB communication activity.
5.7.2
A second application of the ZSTAR USB stick is a computer mouse demo. This application looks like a
real USB mouse. Movement of the cursor on screen is done very simply by tilting the sensor board in axes
XY. The first two buttons on the sensor board have the same functions as buttons on a real mouse. The
third button, introduced on the new ZSTAR3 sensor boards, substitutes the wheel of a real mouse. When
this button is pushed, the cursor stops moving on the screen, and the USB stick starts to generate wheel
movement from the Y axis. Only the sensor board with index 0 can work as an input device.When Mouse
application is active, LED3 is blinking fast (15 Hz)
