Hi!
What could be the problem, if in my basic hand controller the 2x speed doesn't working, unless I disconnect the hand controller and back?
The other speed is working perfectly.
If I select the 2x speed (short the GPIO_PIN0 (D21) to the GND through a 3.9K resistor) and press the buttons .... nothing. But if I hold any direction button pressed during disconnect the hand controller - and then back - the movement is working. But after I release the button and press another one it doesn't working again.
/Arduino Mega version with protoshield
Hand controller connected to the ST4 port
