Re: [AVR-Chat] RF communications

2006-03-10 by Bryan Martin

Well thats a yes and no.  I currently have a 12v wall wart going into a 
NX1000 dev board.  From there I take 12v off the nx1000 and go to the stk500 
dev board.  I also take 5V off the nx1000 and go to the VCC and ground plane 
of the breadboard that holds the RF modules.  I think I will try to clean 
this up first in hopes that is the pblm.  I will try to drop the NX1000 dev 
board all the way out of the picture first and hook the wall wart direct to 
the SDK500 even though that will still be pushing 5.8v when taking the pins 
high.  That would be controlled by the STK500 I think.
