# SSD1322 OLED display driver
Pure Rust driver for the SSD1322 OLED display chip, for use with
[embedded-hal](https://crates.io/crates/embedded-hal).
## Description
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](https://github.com/jamwaffles/embedded-graphics)
`Drawing` support.
- Parallel interface support.
- Chip select and bus sharing (assumes /CS is tied low).
- Text mode and/or fonts.
