Joystick enabled version of USBHID -library. Has full Playstation 3 functionality including button pressures and a working home-button implementation, while maintaining full PC/MAC/linux -compatibility. basic operation of the lib: #include "mbed.h" #include "usbhid.h" USBJoystick joystick; int main() { while(1) { char dpad = 0xf; /*only the rightmost 4 bits matter*/ short button = 0xff; /*only the rightmost 13 bits matter*/ /*buttons are square, cross, circle, triangle, l1, r1, l2, r2, l3, r3, home.*/ char stick1x = 0; char stick1y = 0; char stick2x = 0; char stick2y = 0; joystick.joystick(dpad, buttons, stick1x, stick1y, stick2x, stick2y); wait_ms(5); } }
