it really means. Can somebody describe what is a bootloader and the
benefits for PIC projects...

Hi, I'm having big trouble getting the tiny bootloader to work on my 16F877. The original one isn't ready for the pic16f877 or the pic16f877A. And I haven't managed to modify the...

And you can't afford to have a small 6 pin header, or 6 in-line pads
for programming via ICSP? ICSP also gives you the ability to debug
once the chip is mounted, so...

I couldn't get ICSP to work with a 16F628 and an Olimex PG-2C so I
decided on a 16F88 with a bootloader:

upand_at_them - Aug 8 2004
All the examples I've seen for ICSP use a MAX232, but the PICAXE 18X,
which is a PIC16F88, has a simple two-resistor serial interface.
Any reasons why I can't u...
