This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for HUB75 RGB LED matrix displays
IMPORTANT: This software is meant to be used with the spin-standard-library (P8X32A) or p2-spin-standard-library (P2X8C4M64P). Please install the applicable library first before attempting to use this code, otherwise you will be missing several files required to build the project.
- 3bpp color (8 colors), treated internally as 8-bit format
- Integration with generic bitmap graphics library
- x kB for display buffer, where x == panel width * height (e.g., 64x32 = 2048, or 2kBytes)
P1/SPIN1:
- spin-standard-library
- graphics.common.spinh (provided by spin-standard-library)
- 1 extra core/cog for the HUB75 engine
P2/SPIN2:
- p2-spin-standard-library
- graphics.common.spin2h (provided by p2-spin-standard-library)
- 1 extra core/cog for the HUB75 engine
| Processor | Language | Compiler | Backend | Status |
|---|---|---|---|---|
| P1 | SPIN1 | FlexSpin (6.8.0) | Bytecode | OK (not recommended) |
| P1 | SPIN1 | FlexSpin (6.8.0) | Native/PASM | OK (recommended) |
| P2 | SPIN2 | FlexSpin (6.8.0) | NuCode | OK (untested) |
| P2 | SPIN2 | FlexSpin (6.8.0) | Native/PASM2 | OK |
(other versions or toolchains not listed are not supported, and may or may not work)
- Tested using Adafruit 64x32 panel (NOTE: Due to the many variations of components used on these panels, the driver may not work for all without modification)
- Tested up to 180MHz Fsys on P2 (display was somewhat unstable at this speed)
- No brightness support
- No support for higher color depths
- Driver is currently written in spin (too slow to be of practical use when compiled as bytecode on P1; building to native code using FlexSpin is highly recommended)
