LED touch controller – lamp driver

[Vermes]

This LED lamp driver was based on Atmega128 and it uses graphical display with the touch pad. Program was written in Bascom and occupies 45%, the half of which consists of graphics and animations.

There are six independently controlled hardware PWM channels. It is possible to set the time of sunrise and sunset as well as enabling and disabling times of the individual channels. You can also add some extras such as weather effects (cloudiness, storms, moon phases).

The controller controls current pulse drivers MBI6651, but it can work with every drivers that have the input for PWM signal.

The schematic may slightly differ from the PCB, because some improvements were introduced, the PCB is double-sided.
