Picaxe project board inputs/ best way to remove pulldown
May 10, 2011
Some devices sending input data seem not like pull down resistors. I should make changes to my 20pin and 28pin board settings to connect for example digital temperature sensor. With outputs i can connect devices straight to picaxe pins. Put i suppose this won't help regarding the inputs, pulldowns can't be "jumped over"?. However there are these holes next to pic on my 20 board.What are those holes for?
So my question is: have you found clever ways to alter board designs to connect devices needing for example pullup resistor instead of pulldown?
Do you have experiences of internal pullup? Could i just leave board without pulldown and use this as default setting?
