Hello All: I just started to build my own simple programmer for the 18F devices, = but I'm having trouble communicating with the chip. I've built a small = plataform based on 16F628 that can receive commands from the RS232 and = transmit then to the target device (18F). I was succesfull reading and = writing the 16Fxxx devices, but can't do the same with 18F devices (Hey, = I know that the protocol is different). Anyone has experience on transmiting serial commands to program these = new chips ??? If anyone could help, maybe we could soon have a free = programmer (and maybe an ICD too) for these new devices. I'm planning to = write the PC frontend software in delphi 6. If anyone has interest, = maybe we could make these chips more accessible to the PIC comunity.
