ISP Hub75 Matrix Driver

Overview

Driver for HUB75-controlled RGB LED Matrix Panels

NOTE: This P2 HUB75 driver is built to work with the P2 Eval HUB75 Adapter which is available from HUB75 at Parallax.com Store

A selection of the driver features:

Up to 3 HUB75 cards supported on a single P2
Compile-time selectable color depth from 3 to 8-bits per color (9 to 24-bit color per pixel), per hub75 card
P2 P2 Cube support (display on all six surfaces of the cube)
Single panel support working well for supported chips, up to 8192 LEDs (128x64)
Supported Panel Driver Chips: DP5125D, FM6126A, FM6124, GS6238S, ICN2037, ICN2038S, and MBI5124 (1/8 scan)
Multi-panel support is working well for ICN2037 chip only (we're trying to figure out the panel initialization sequences for chips like the FM6126A. Until we do, Multi-panel won't work for these panels)
Displaying text in 5x7 and 8x8 fonts (including Chip's dithered 5x7 fonts and with descenders!)
Initial version of scrolling text - will get more performant in future updates (now up, down, right, and left scroll!)
Basic color pixel placement at row and column (whole panel-set and Single-panel-of-set forms)
Basic drawing primitives (whole panel-set and Single-panel-of-set forms)
Loading and displaying images from .bmp files (that are identically sized to your single panel)
