NS73M fm radio trasmitter

[SmugWimp]

Joe,

I appreciate all the help and suggestions.

Here is my code, a schematic, and a photo of my setup.

I have tried all kinds of things, and my underlying suspicion isnt that I am doing something wrong. I am just not finished with what is right.

I have rewritten my code more similar to Boris' snippets, and his seems to work, heh. But mine still does not. Yet.


My Configs are set as follows:

__config _HS_OSC & _WDT_ON & _LVP_OFF & _CP_OFF & _WRT_OFF & _CPD_OFF & _BODEN_ON & _PWRTE_ON

PAUSE 10 ' Don't know if this is necessary, but everyone writing to EEProms use it, I figured it couldn't hurt.
RETURN

LCDSTUFF:
LCDOUT $FE, 1
LCDOUT $FE, 2
PAUSE 500
LCDOUT $FE, $80
LCDOUT "  Are We" 
LCDOUT $FE, $C0
LCDOUT "Transmitting ??"
PAUSE 1000

THEEND:
END

I know the chip in the schematic says "16F84AP". disregard that. In reality, it is a 16F877A; the pin connections are the same still.

Any ideas would be a godsend. Thanks!

Cheers!
