Sorry if this a redundant question, but i'm having difficulty with getting RF communication to work.
Here's what I've done so far. I picked up a matched transmitter receiver combo. Wired them up per the data sheets. On the two pics (18f1320) I've enabled the hardware usart. My data packet structure is to send (3) 255's then the data. When i wire the two chips up directly this works fine, the data comes thru no problem, when i run this sequence to the transmitter... i get nothing.
I've read thru several tutorials on this subject, and i seem to get different info from all of them. Some say i need to transmit 20 1's, some say i need to invert the RS232, and some say it should work just as what i've done. soooo....
my question is what's the real story with these. Oh I'm using C18 as my language.
thanks in advance to anyone that can shed some light on this subject.
