Pullup no works

(1/2) > >>

I have an ardruno sketch that when I compiled it in wiring I noticed that the pullups no longer worked.  I have tried in vain going from

digitalwrite(XXX, HIGH)

no worky ATML328P 16mhz

can you post your sketch, explain a bit about what you want it to do?

Also, which board are you using?

Thanks for the quick responce

I have a key pad and some buttons in the sketch that worked fine in ardrunio land.  I used the writedigital to use the internal pull up resistors.  Now some of the pins (A3) for one and some of the keypad pins no longer work   

I am using the Adrurino Pro (5V 16Mhz) w/atml328

As an aside I can get the keyboard to work fine in wiring when I use just the Keyboard example sketch

//int incomingByte = 0; // for incoming serial data

Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );

Any word on this issue.... do you need more info

Just after a quick look, I think the problem is that you're using the "A3" constant - which will result in an entirely different result than what Arduino has done with those constants.

Here is what you should change:

--- Code: ---const int FADEAMOUNT = 10;
const int PUSHBUTTON = 12;
const int RESET = 27;   // A3;
const int GREENLED = 9;
const int REDLED = 24; // A0;
const int YELLOWLED = 10;
const int REL1 = 25; // A1;

--- End code ---

Try that.
