You're Welcome!!! I would be happy to help if you need any of the info I have. I am not a programmer, so my program logic could be flawed, and certainly can be improved! I tried to comment it enough so that I can decipher my own coding for future use. I have pretty much stripped the control board of a 2008 model 8110. It is much easier to identify components, and guess at their intended use when you can see the circuit connections. It would probably be MUCH more useful to a majority of Intex owners if the SONIX MCU could just be re-programmed in place. Any SONIX experts out there????
There are some other Intex control projects here - http://x.havuz.org/viewtopic.php?f=26&t=1101&sid=c81c7e315d93598d31ba11e7f7b10cc8
which is where I got some of my ideas from.I also got the best idea, to use the Arduino, from this post - http://www.troublefreepool.com/diy-automated-controls-advice-solicited-t5708.html
which is what really inspired me to get going! TFP is a really great forum for any pool owner, too!!!
