1. Here’s a quick video of the LED Driver board I posted about previously. This video shows the driver board controlling 16 RGB LEDs cycling through the HSL colour space.

    Getting the HSL to RGB conversion to work on a PIC proved a little tricky (most examples on the web assume floating points, or 32bit integers). But after much fiddling I got it working fairly well, though I suspect many improvements can be made yet.

    Next we need to make another copy of the board using a PIC with hardware I2C support to help speed things along, and get it made professionally to confirm the design. Then we make a master board to control all these slave LED drivers, and away we go!

    There’s some additional videos below:
