This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for SSD1322 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 20MHz (P1), 20MHz+ (P2)
- Integration with generic graphics library
- Set display contrast and master current scaling
- Set number of displayed lines
- Set starting display line
- Set panel-specific display offset
- Set draw area for subsequent drawing operations
- Enable display mirroring (H, V)
- Enable display power/sleep
- Display mirroring (horizontal, vertical)
- Set display clock frequency, divider
- Swap pixel data nibble order
- Set GPIO 0, 1 state
- Set Vdd regulator internal or external
- Set Vsl internal/external reference
- Set low greyscale level quality
- Set timings: phase 1, 2, 3 period
- Set Vcom voltage reference level
- Set visibility mode (all pixels off/on, normal display, inverted display)
- Set partial (vertical) display area
- Pixel-doubled (horizontal; 2 display segment drive per pixel) support

| Processor | Language | Compiler | Backend | Status |
|---|---|---|---|---|
| P1 | SPIN1 | FlexSpin (6.9.4) | Bytecode | OK |
| P1 | SPIN1 | FlexSpin (6.9.4) | Native/PASM | OK |
| P2 | SPIN2 | FlexSpin (6.9.4) | NuCode | Runtime issues |
| P2 | SPIN2 | FlexSpin (6.9.4) | Native/PASM2 | OK |
(other versions or toolchains not listed are not supported, and may or may not work)
- Tested with Newhaven Display 3.12" 256x64, NHD-3.12-25664UCW2
- Tested with Newhaven Display 2.7" 128x64, NHD-2.7-12864WDx3M (H pixel-doubled)
- Pixel-doubled display refresh is slow on the P1; PASM build is recommended
