# mcp2003a
Embedded Rust Microchip MCP2003A LIN transceiver driver with embedded-hal traits for no-std environments.
Uses `embedded-hal` digital traits for GPIO and `embedded-hal-nb` Serial traits for UART.
- `embedded-hal = "1.0.0"` - Major breaking changes versus 0.2.x implementations.
- `embedded-hal-nb = "1.0.0"` - Additional non-blocking traits using `nb` crate underneath.
**⚠️ WORK IN PROGRESS**

## Usage
Add the crate to your `Cargo.toml`:
```
cargo add mcp2003a
```
Configure like so:
```rust
let lin_bus_config = LinBusConfig {
speed: LinBusSpeed::Baud19200,
break_duration: LinBreakDuration::Minimum13Bits,
wakeup_duration: LinWakeupDuration::Minimum250Microseconds,
read_device_response_timeout: LinReadDeviceResponseTimeout::DelayMilliseconds(2),
inter_frame_space: LinInterFrameSpace::DelayMilliseconds(1),
};
let mut mcp2003a = Mcp2003a::new(
uart2_driver,
break_pin_driver,
delay,
lin_bus_config
);
mcp2003a.send_wakeup();
mcp2003a.send_frame(0x01, &[0x02, 0x03], 0x05).unwrap();
let mut read_buffer = [0u8; 11];
let len = mcp2003a.read_frame(0xC1, &mut read_buffer).unwrap();
```
