[xpa999]

Here's a thought. Thorsten Klose uses a MIDI interface as a serial port with a bootloader. It has several advantages: 1) cheap usb interface, less than $10 on ebay. 2) optoisolator to eliminate grounding issues between the pc and the device, 3) the MIDI interface is easy to access from the pc side.

just a thought.

Would epoxy on the PIC prevent someone from reading the PIC?

I remember we've had this discussion before.

Chinese read the wafer itself, by laser cutting the chip open. So, epoxy is a problem to them? I do not think so.

Happend to me before...
