Here is a list of direct links to the various project pages. All of the things described here utilize 68HC811E2 in 52-pin PLCC package.
My MCU board schematics. This board is not a bad way to start. As primitive it is - yet you can write and run a program on the device's internal memory.
"Power Up"...Let's see if the puppy is alive. Not the best way to verify if your chip is alive, but quite simple - really.
Simple program in bootstrap mode. Well this was my first program for 68HC11. It is one of the simplest things possible, but it is a great way to learn how to master the GCC switches.
My crude boot loader software for download (Win32). There are probably a gazilion programs which load a bootstrap code into the MCU in boot mode. Well I wrote this one myself. It is native Win32 C code. Oh, yes source code IS available.
GCC How To. How to compile our simple program using the GCC cross compiler.
Add RAM and
LCD...
A simple extension board to add RAM and a LCD interface.

for 68HC811E2
Simple EEPROM OS like program - if you want to learn how to write an OS for your 68HC11 check this out.
