Implement full SSD1306 OLED display support: - Splash screen on boot (1.5s) with project name, version, board - Dashboard showing radio state, config, counters, RSSI/SNR - RSSI history sparkline (64-sample ring buffer, 2px-wide bars) - DisplayOn/DisplayOff host commands routed via dedicated channel - Pure render functions against generic DrawTarget (no hardware coupling) - Display on/off control bypasses radio task entirely Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

rust-bitfield
|
|
=============
|
|
|
|
This crate provides macros to generate bitfield-like struct.
|
|
|
|
This a complete rewrite of the `bitfield` crate.
|
|
You can find the previous version in the [rust-bitfield-legacy](https://github.com/dzamlo/rust-bitfield-legacy) repository. This version works on the stable version of rustc and use a different syntax with different possibility.
|
|
|
|
|
|
## Example
|
|
|
|
An IPv4 header could be described like that:
|
|
|
|
```rust
|
|
bitfield!{
|
|
struct IpV4Header(MSB0 [u8]);
|
|
u32;
|
|
get_version, _: 3, 0;
|
|
get_ihl, _: 7, 4;
|
|
get_dscp, _: 13, 8;
|
|
get_ecn, _: 15, 14;
|
|
get_total_length, _: 31, 16;
|
|
get_identification, _: 47, 31;
|
|
get_df, _: 49;
|
|
get_mf, _: 50;
|
|
get_fragment_offset, _: 63, 51;
|
|
get_time_to_live, _: 71, 64;
|
|
get_protocol, _: 79, 72;
|
|
get_header_checksum, _: 95, 79;
|
|
get_source_address, _: 127, 96;
|
|
get_destination_address, _: 159, 128;
|
|
}
|
|
```
|
|
|
|
In this example, all the fields are read-only, the _ as setter name signals to skip the setter method.
|
|
The range at the end (e.g. 3, 0) defines the bit range where the information is encoded.
