The link I gave in the previous post points to a forum entry from a year ago. I found that that old forum post seems to have an invalid link in it. I have changed it so that the links now work:

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:
