Hello Schnee,
Thanks for your reply!
I had connecting the IOIO to Tb6612 like the picture, and I set all pin to
output 3.3v . PWM frequency was set 100
but it still didn't work , when I turn on the power, it turns on for a
split second then back off.
This is my setup code , is there anything I missed ?
protected void setup() throws ConnectionLostException {
led_ = ioio_.openPwmOutput(39, 100);
ain_ = ioio_.openDigitalOutput(40, false);
bin_ = ioio_.openDigitalOutput(41, true);
cin_ = ioio_.openDigitalOutput(42, true);
}
public void loop() throws ConnectionLostException{
led_.setDutyCycle((float)1.0);
try {
Thread.sleep(10);
} catch (InterruptedException e) {
}
}
}
Thank you for your help!!
best regards
Jack
