If I can down load to another PIC why can I not download to my main PIC? I have no problems with pin count. I am not using a PIC KIT. I am using a naked 44 pin 16F887 and a solderless prototype board.

It would seem that part of my code could react to some signal from the USB serial port and download parameters into itself. I have not the faintest idea how, however.

Another thought: My code is written so that all the constants are defined in the preamble before "main:". A class of eight to ten students, I imagine, would be broken into four or five teams. They could change parameter values using a text editor, burn into a thumb drive (or use the school's internal network), cut and paste the data into their PBP code on the licensed machine, compile, plug the USB connector into their car, and download using PICKIT programmer. WRONG? Against the rules?

I never got MPLAB to work as a ASM compiler and chip programmer.
