Hello, I have some experience with PBP but I do not know all of the commands. I was curious as to whether I can use HSERIN1/2, HSEROUT1/2, SERIN1/2, SEROUT1/2 for input and output for transmission for RF. I would like to use PWM. I was wondering how I would go about transmitting a value one bit of a time out serially. Any suggestions or advice I would find very helpful. Thanks.

Hello Jblackann,

I have posted a example in the FAQ area. Take a look at "Serial communication" if you have any more questions, or if I misunderstood your question, please ask.

Well, for RF transmission it is necessary to use some kind of encoding, like manchester. That way data slicer on the receiver end will never reach either end of supply but sit in the middle of it.

What you do is always send two bits for each bit of information, like 1 transmits as 10 and 0 as 01. Always 50% of duty cycle is maintained.

If you have more questions, try to search the picbasic forum on melabs site or e-mail me.
