Uses the trackball motion to move the mouse pointer, pushing down on the trackball will trigger a microswitch which will act as a left button click, and the LEDs under the trackball will be lit different colours depending on what the user is currently doing with the device (red for no motion, green when the trackball is being moved, and blue during button clicks). It does use some other utility classes from acceleration.h to provide acceleration to the trackball motion. */ #include <mbed.h> #include <USBMouse.h> #include "acceleration.h" int main() { static USBMouse Mouse; static CAcceleratedTrackball Trackball(p20, // BLU p25, // RED p26, // GRN p10, // WHT p5, // UP p6, // DWN p7, // LFT p8, // RHT p9); // BTN for(;;) { int DeltaX; int DeltaY; int ButtonPressed; Trackball.GetState(DeltaX, DeltaY, ButtonPressed); Mouse.update(DeltaX, DeltaY, ButtonPressed ?
