Library to handle SpaceBall, SpaceMouse and SpaceOrb on serial port. Gets access to 3D rotation and translation vector as well as button status. (USB is not supported)

All handling and decoding is done in the RX interrupt and the vector values can be read out asynchronously with different coordinate mappings.

Example:

#include "mbed.h"
#include "SpaceBall.h"
 
PwmOut led[] = {(LED1), (LED2), (LED3), (LED4) };
SpaceBall SBall(p9, p10);   // tx, rx, bSOrb
 
int main() {
    SBall.Init();
    
    while(1) {
 
        led[0] = abs( SBall[TX] ) + abs( SBall[TY] ) + abs( SBall[TZ] );
        led[1] = abs( SBall[RX] );
        led[2] = abs( SBall[RY] );
        led[3] = abs( SBall[RZ] );
        
        wait_us(500);
    }
}

In this exaple the 4 LEDs are powered dependent on force at the Spaceball. LED1 shows the sum of all translation forces. LED2 to LED4 shows the rotation forces.
