Hi,
is it possible to set a pull up resistor after defining a pin as INPUT?
Nothing about that in the tiny reference. If not, what can I do? Solder?

have fun

the current arduino language doesn't have a specific instruction to do that but I think
that using  digitalWrite(thePin,HIGH) while thePin has been defined as an INPUT should
turn on the internal 100k pull-up resistors.

give it a try...

so that's how it works at my c-control which is based on the amtel ATmega32
