Simple Two IC ICD2 Emulator

[William at MyBlueRoom]

I've put up a schematic Inchworm; on my site http://www.myblueroom.com
of my take on the many fine designs of Microchip ICD2 emulators on the
web. It's based mostly on the excellent version by Lothar Stolz.
I've used the MAX232 as a voltage tripler to get the ~12.5v needed for
VPP and added handy busy & power LEDs.

You will need to program the bootloader .hex file located in the ICD2
directory onto a 16F876 (or 877)

It's on the Microchip web site.

It's on the Microchip web site.

This directory has 51 .hex files in it.

C:\Program Files\Microchip\MPLAB IDE\ICD2

Which one ??

That look like your hard drive, not the Microchip web site!

so how do I get to the ICD2 directory to get the .hex file?

You have to first install MPLAB (I'm using 7.40)

The load the file BL010101.HEX

It's generally found here on your harddrive.
C:\Program Files\Microchip\MPLAB IDE\ICD2\BL010101.HEX

You will need a simple programmer to get the bootloader on the first
time. PonyProg is one example of a simple RS232 port programmer (the
schematics are on the site http://www.lancos.com/prog.html ). You
should be able to hand wire the PonyProg in about an hour or two. You
only need to program the bootloader once.

PS make sure you do NOT use a 16F876A or 16F877A they require
specially modified bootloaders.
