trouble with xbee code

gennarobasso81 · 2012-10-01 20:08

hello all,

I am having trouble with some code for an xbee. overview of project is i have two bs2's connected to xbees, I have one bs2/xbee with two pushbuttons the other with two different colored led's. I am trying to get it so one pushbutton will control one color and the other pushbotton the other color.

problem i am having:
regardless of what button is pushed the lights go on in a pattern. first the green, then the red. If i hit Pushbutton one 5 time it will go green, red, green......and so on. it i hit any combination of the two buttons it still repeats the pattern of green, red, green, red, green,...and so on

As it is now your receiving code has no way of skipping over either of the LEDs.

do you know a good way to use an IF / THEN statement with the serin Rx. I played around with a lot of different variations of the code.

this is one example. It was all i had to show because i didnt save any of the non working codes.

Place what you receive from SERIN into a VAR then drive the LEDs based upon the contents of that VAR.

thank you for ur advice. I did try this before but after revisiting and trying again i got it.
