using the buttons with the ATmega

[rickseiden]

Is there any way to use the buttons \on the Gertboard with the ATmega chip on the Gertboard?

Would it be as simple as hooking up the ATmega pins to the buffer pins? I think you'd need to connect a pin to a pull up/pull down resister, wouldn't you?

Thanks
Rick

This seems to work, but I want to get someone like Gordon to say it's right, because I'm such a noob.

Code: Select all

3.3v ----/\/\/\/\-----+--------/ ----- Ground
           10K        |        s1
                      |              
             ATmega Input Pin 

I used this with the Button example, and it appeared to work just fine.

There's an example for the use of buttons with the ATmega in the Gertboard manual (p 33-34).

Links for Gertboard docs can be found here: http://www.raspberrypi.org/phpBB3/viewt ... 42&t=20410

Guess I should have kept reading until I got to that page, huh? RTFM, Rick. RTFM!
