First you build or buy a programmer for your target device. Then you start at wikipedia to learn the specifications for a hex file.=20 Next, write a program to read the hex file and send it to the programmer=20 in the proper format for the programmer. Test, re-write, re-test until it works. If it's a PIC you want to program, MPLab has menu selections to load hex=20 files.
