I had sorta thought about that..........but I've always wondered how you tell what memory is not going to be used for the program. I always make the code non-relocatable when asked, but how do you..........

Wait a minute, do you just read the chip and look at the hex dump to see what spots are left blank after the program is in it? Is it that simple? Then you just pick an area that isn't being used? Am I on the right track?

That's a great idea! It would certainly lower the serial data overhead - from 39 bytes per transmission to 11. I know, not a lot of data either way, but less chance of errors when the receiver is in a race car!

Thanks
