problem with testing hexcrawler pushbuttons
I am following along in the hexcrawler manual - now at chapter 5, testing the pushbutton controls. have HexCrawler_Pushbutton_Test.BS2 loaded and 'kind of' working.
My debugger box shows messages of '0' when starting.
pushing button on pin8, changes to show a '1' in the debugger, but pushing the button for pin 12 causes both to say they are pressed. I have checked the wiring over and over. moved the circuits around a little, moving them further apart. I even removed button 8 and its 220 resistor going to the Vss, and i still get the same message (8 and 12, 1 and being pressed when I press button 12).
Help!

This seems like there is a wiring issue or a coding issue, I have this up and running in front of me and it works just great.· Make sure to download the "Button" code from this link:· http://www.parallax.com/detail.asp?product_id=30063·.

I ended up getting it to work. i did what you suggested and copied the code into my own document, and re-ran the token.
It seemed to work, but i swear i could not find any coding errors before. Would the direction of the resistors have anything to do with it? i understand the gold end should always be directed towards the flow of electricity?
...anyways, its working. But now, I have to wait for a new PSC - it seems this one was not programmed before being shipped out. It wouldn't send back the firmware information to my debugger.
The resistors that we use are not polarity sensitive.· I'm glad that you able to get to work.
