This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for Solomon Systech SSD1351-based OLED 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.
- SPI connection at fixed 20MHz (P1), up to 20MHz (P2); 4-wire: DIN, CLK, CS, DC (and optionally RESET)
- Integration with the generic bitmap graphics library, as well as some support for unbuffered, direct-to-display operations
- Display mirroring, rotation
- Control display visibility (independent of display RAM contents)
- Set subpixel order
- Set color depth (16, 18-bit can be set; currently only 16-bit supported by driver)
- Set contrast/brightness (individual color channel as well as a master scaling factor)
- Low-level display configuration settings: Precharge periods and levels, Oscillator freq and divider, logic levels
P1/SPIN1:
- spin-standard-library
- P1/SPIN1: 1 extra core/cog for the PASM SPI engine
- graphics.common.spinh (provided by spin-standard-library)
P2/SPIN2:
- p2-spin-standard-library
- graphics.common.spin2h (provided by p2-spin-standard-library)
| Processor | Language | Compiler | Backend | Status |
|---|---|---|---|---|
| P1 | SPIN1 | FlexSpin (6.9.0) | Bytecode | OK |
| P1 | SPIN1 | FlexSpin (6.9.0) | Native/PASM | OK |
| P2 | SPIN2 | FlexSpin (6.9.0) | NuCode | OK (Untested) |
| P2 | SPIN2 | FlexSpin (6.9.0) | Native/PASM2 | OK |
(other versions or toolchains not listed are not supported, and may or may not work)
- Tested with Adafruit P/N #1431, Newhaven P/N NHD-1.5-128128ASC3
- Maximum display resolution is limited when using buffered mode with the P1 driver, due to memory usage (doesn't apply when built #defining
GFX_DIRECT) - Reading from display not currently supported
