#146580 - LP programming
Responding to: ???'s previous message
Yes, I use a ATMEL ISP programming cable and software for smaller designs where the ATMEL AT89LP chip is surface mount and can't be removed to be put into a programmer.

Used the same 10 pin header to plug in a small keyboard I designed to finish up the project. Found the dangling reset line to be a problem and had to include a 300K resistor to ground on the keyboard to prevent sporatic resets.
