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)
