// test code, this demonstrates working motor drivers. 
// full reverse to full stop, dynamicaly brake and switch off.
#include motordriver.h
Motor A(p22, p6, p5, 1); // pwm, fwd, rev, can brake 
Motor B(p21, p7, p8, 1); // pwm, fwd, rev, can brake
int main() {
    for (float s= -1.0; s < 1.0 ; s += 0.01) {
        A.speed(s); 
        B.speed(s); 
        wait(0.02);
    }
    A.stop();
    B.stop();
    wait(1);
    A.coast();
    B.coast();
}
