Radio TX and RX code

[Joerideman]

I have tried, to put the transmitter code in a 18F242, but I get errors in the include code. Is it possible, to get this code working for a 18F pic?

I spent ages trying to squirt a few bytes of data across a wireless link, I found the most important thing is the PREAMBLE, if this doesn't balance up the data slicers (yes I KNOW we've been over that a million times before) that data transmission is very unreliable, so I can up with the simply TX and RX code for proving the link.

VERY SIMPLE, all this does is fire a byte $FF) over the link, then every time the Rx sees $FF it increments a count. Best I've had is 480,000 bytes sent with NO loss, and this was over a 40ft link using very low power, hook-up wire for an antenna (35cm). The RX module was placed two feet from a high power WiFi router and two cordless telephones. I even sat next to it using a mobile phone and using my car "blipper" (also on 433.92MHz) and still it only dropped a few (end result show 0.334% lost data) packets.

OK for lengthy data packets this would not be the best solution, but if you just want to trigger an alarm or send temperature, this is a far simpler way that getting hooked up with Manchester encoding or CRC and error correction.

If it's big packets you want to send, use Tims code, it's bombproof.
