Some people suggested putting this information into a new thread so that others could access it easier. I decided that this was a good idea up to a point. So here I provide some clickable links to the information.

First off there is that rather long original posting I made to show how the state machine / time slicing design can be approached. Note this is just one implementation scheme. I know that there are other methods which probably number up to matching the number of 8052 programmers!!. Here is a link to the original tutorial posting.

Original State Machine Tutorial

I later reviewed the non-debugged code shown in the original post for the sample state machine tutorial and I found a number of small errors and typos in the code. I have uploaded the updated code to my 8052.com home page. It is available at the following link to view or download.

Updated State Machine Code

For those interested in downloading the schematic that shows the connections for the switches and LEDs in the configuration used by the above state machine code you can click the link below:
