Crate colorlight 

Colorlight receiver-card layer-2 protocol: raw Ethernet frames whose 2-byte “EtherType” is a packet type. Frame builders and reply parsers only; sequencing lives in the callers. Byte layouts: docs/pixel-protocol.md.

Re-exports

pub use discovery::*;

pub use flash::*;

pub use pixel::*;

Modules

discovery

Discovery, layout, test mode, parameter reload, and the upgrade-descriptor query.

eeprom

The receiver’s EEPROM (cabinet identity) and the type-0x1900 frames that write it: opcode 0x85 writes one record, 0x87 commits to the flash mirror.

flash

Flash read, erase and write frames.

params

Sub-indices of the type-0x05 real-time parameter packs.

pixel

Pixel rows, the latch (sync) frame, and brightness: the frames sent every refresh.

upgrade

SDRAM-staged firmware upgrade: descriptor query, 1 KiB chunk uploads (unacknowledged; the caller paces them), erase, program, completion poll.

Structs

Colorlight

The Colorlight receiving-card protocol: the free functions of this crate behind Protocol.

Constants

BROADCAST

Receiver index addressing every card on the link. The vendor uses it even for one card, and a card with a corrupt cabinet record answers only to it.

CARD_MAC

HEADER_LEN

Two MACs and the type.

SENDER_MAC

Traits

Protocol

One vendor’s wire protocol as frame builders and reply parsers, the surface ops drives a card through.

Functions

frame

frame_with

A frame with a zeroed payload_len-byte payload that fill writes in place.
