Hi sir,

the project is quite interesting, could you kindly share the code pl.

regards

Hi Justin, I am starting a computer engineering course at my school and would like to try building this. I have everything already except the LED strip, but that is easy to come by. Can you also if possible send me the programming (PICBasic or even in a text file) so that I can get my students to perhaps just program one sequence? This is VERY COOL!!! email:jbiro@cogeco.ca

Hey! I was asked to do a simple pic project for school and this is great, but I have to understand and explain how the code works and I see you only posted the .hex file, could I get the original code please to razielconz.7@gmail.com? You'd help me out a lot!

Also, do you think something similar could be done to drive an RGBA luxeon-like LED?

can this code be put on a pic 16f627-04/p chip? it has 8 legs but im sure I could put it in the circuit if the code would work.
Jestin_Cubetech (author)  aclark321 year ago
hmm no...
The 12F629 is almost exactly identical to the 12F675
- the only difference is that it does not have an ADC.

thanks for the reply and the code... looks like Im just gonna have to go buy me a 12f675 then. Im lucky enough to have an ESCO store in my city and they stock just about any pic controller you could want.. they stock a lot of other stuff too... the only part Ive ever had to order there was a mosfet for a Rockford fosgate amp I was repairing... look for one in your area.. its called ESCO,,, Electronic Supply Company...
