I have a project where I am trying to send rs-232 data one way over a commercial low power radio module, & am trying to use a 16f627 to encode the data on the transmit side & another 16f627 to decode the data on the receive side. I have no control over the rs-232 data, since it is being generated by another device @ 4800 baud with only Tx & SG signals. I am very new to programming PIC's, so I really don't even know where to begin. Would anyone have any experience with this type of application, or have any suggestions on where to start? I have searched everywhere I can think of, but all I have found so far have been general references to Manchester Encoding, nothing detailed enough to get me started. Any help would be greatly appreciated. Thanks, David -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
