SSD1322 OLED display driver

Pure Rust driver for the SSD1322 OLED display chip, for use with embedded-hal.


This driver is intended to work on embedded platforms using the embedded-hal trait library. It is no_std, contains no added unsafe, and does not require an allocator. The initial release supports the 4-wire SPI interface.

Because the SSD1322 supports displays as large as 480x128 @ 4bpp, the primary API uses a Region abstraction to allow writing a stream of pixel data from an iterator onto a rectangular sub-region of the display area. This avoids the requirement to buffer the entire display RAM in the host, since such a buffer would consume a colossal (for a μC) 30kiB of RAM.

Missing features:

  • embedded-graphics Drawing support.
  • Parallel interface support.
  • Chip select and bus sharing (assumes /CS is tied low).
  • Text mode and/or fonts.
