Detailed Description

UART driver interface - canonical types for MCU driver implementations.

This header documents the UART driver interface that MCU drivers implement.

Drivers implement the following static interface: static void init(uint32_t baud_rate); static void write_byte(uint8_t byte); static void write(const uint8_t* data, size_t len);

Optional methods for bidirectional communication: static bool available(); static uint8_t read_byte();

Usage in driver: #include <sbl/hal/uart/driver.hpp>

Design Notes

UART is designed as a simple debug output interface. The initial implementation focuses on TX-only operation for debug logging. RX support can be added later for MIDI input or debug console features.

The driver uses polling/blocking mode for simplicity. Interrupt-driven or DMA modes can be added as separate driver variants (UartAsync, UartDma) if needed.
