Full Color Bargraph

System 0.0.7

I think I’m finally starting to understand how we will drive our bargraphs if we want colors (green, yellow, red). Assuming that we have 64 RGB LEDs per bargraph (128 on a dual bargraph), we will need 12 AS1112 16-channel drivers per bargraph, because we need 4 of them per color, and an RGB LED is essentially three LEDs within a single package. That means 24 drivers per bargraph board, since we have 2 bargraphs per board. But at 5×5mm, we should not have any problems fitting them on a 13×150mm board. And as far as RGB LEDs are concerned, we should go for the Harvatek HT-B3053FCH, which measures a mere 1×1mm.
