# About the display
- Resolution: 352x160=56,320 pixels
- Pixels are grouped into 44x20=880 tiles (8x8=64 pixels each)
- Smallest addressable unit: row of pixels inside of a tile (8 pixels = 1 byte)
- The brightness can only be set per tile
- Screen content can be changed using a simple UDP protocol
- Between each row of tiles, there is a gap of around 4 pixels size. This gap changes the aspect ratio of the display.
### Binary format
A UDP package sent to the display has a header size of 10 bytes.
Each header value has a size of two bytes (unsigned 16 bit integer).
Depending on the command, there can be a payload following the header.
To change screen contents, these commands are the most relevant:
1. Clear screen
- command: `0x0002`
- (rest does not matter)
2. Send CP437 data: render specified text into rectangular region
- command: `0x0003`
- top left tile x
- top left tile y
- width in tiles
- height in tiles
- payload: (width in tiles * height in tiles) bytes
- 1 byte = 1 character
- each character is rendered into one tile (mono-spaced)
- characters are encoded using code page 437
3. Send bitmap window: set pixel states for a rectangular region
- command: `0x0013`
- top left tile x
- top left _pixel_ y
- width in tiles
- height in _pixels_
- payload: (width in tiles * height in pixels) bytes
- network byte order
- 1 bit = 1 pixel
There are other commands implemented as well, e.g. for changing the brightness.

<Description>
C# bindings for the rust crate servicepoint. You will need a suitable native shared library to use this.
For documentation, see the rust documentation: https://docs.rs/servicepoint/latest/servicepoint/.
Note that this library is still in early development. Breaking changes are expected before 1.0 is released.
