Serout/serin issues, advice required

[Agent36]

Hi Brian,
Thanks for the info, I have just searched biphase and found a couple of posts. How do you encode and decode in laymans terms?
This is as far as I have got with my rf;
I can toggle the output of a pic by sending a set of 0's and 1's to balance the data slicer, followed by a data byte. The rf modules I am using are AM and are supplied from RF solutions.
My next step was the code posted above, the aim of this was to control the speed of a motor using the rf modules and pics. By encoding the adc result and out putting it in the form of pwm.
Once I had the code working on the breadboard I transfered it to the Tx/Rx, at this moment in time I can control the motor at a 4 meter range, I have not tried any further as I have not had the time. This has all been acheived using the internal clock set at 8meg, I have taken skimasks advice and ordered some crystals to improve the timing errors. Any other improvements I can make would be an advantage.
Kind regards Nick

You're code show a Manchester Encoding/Decoding routine... so it has to work. Maybe not a bad idea to have a bigger $AA preamble before sending your data.

Crystal are always welcome....

You could still waste quite of your time and try to fine tune the internal one with OSCTUNE register.
