Hi, I have a Top 2048 a pic16f627 and a proto/exp board with serial programming capabilities. I have had great luck with the board and the chip using mikrobasic to generate a hex file then loading that file with the board and it's software. the problem comes when I open one of these hex files and write it to the chip with the top2048 it writes o.k. it verifies o.k. on the top2048 software but when I put it back on the protobord the chip does'nt do anything and when I tell the software for the board to verify it against the hex file I get errors. I am not sure what this config. word does or if that has anything to do with my problem.[blue]
