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.

Hand controller connected to the ST4 port

Hi,

You may have to try a couple of different resistor values. Try with a 4.7k or 6.8k resistor and see if that helps. The 2x speed depends quite heavily on the pull up resistors inside the ATMega.

But also thinking about it, have you connected a 1k resistor between GPIO_PIN0 (D21) and GPIO_PIN2 (D23)? Without that the speed detection won't work properly.

Tom.

Yeppp, the 1K resistor was the problem (I forgot :\ ). At now everything is perfect.
And the new version is excellent.

Thanx for the answer.
