I'm not familiar with the rfPICs but it may be possible to 'cross-wire' from an '877 footprint to an rfPIC target board. This would allow you to mimic the operation of the rfPIC while you develop the code with the bootloader. I've done this for a 16C745 project which let me use an ICD for development (for the non-USB portion, of course). I used conditionals to assemble the code differently for the development and product variations. This mainly involved redefining port equates and the like. Almost all of the code was identical between the two. Regards, Bob -- http://www.piclist.com#nomail Going offline? Don't AutoReply us! email listserv@mitvma.mit.edu with SET PICList DIGEST in the body
