Greetings from South Africa. I require the HEX code or a replacement for the K8064. Dimmer. The part no is: VK8064 PIC 16F676. You may contact me on my email at davewailer@wol.co.za
You could open a support ticket here
http://support.velleman.eu/
Since the K8064 is not an open source project you may not get the code for it
We do not release any source code, you can always order a spare part via your local Velleman dealer
