Bus

enum class fl::Bus : fl::u8

strong

Driver identifier for compile-time bus selection.

The values are deliberately named after the underlying peripheral so a single identifier (Bus::RMT, Bus::PARLIO, etc.) flows through both the template-binding API surface and the runtime registry overrides.

Enumerator
AUTO	Sentinel: defer to DefaultBus<Chipset>::value.
RMT	ESP32 RMT peripheral (all ESP32 variants).
PARLIO	ESP32-P4/C6/H2/C5 parallel I/O peripheral.
SPI	Generic SPI clockless driver.
I2S	ESP32-S3 LCD_CAM via legacy I80 bus (clockless).
I2S_SPI	Original ESP32 native I2S parallel SPI (true SPI chipsets).
LCD_RGB	ESP32-P4 LCD RGB peripheral (parallel clockless).
LCD_SPI	ESP32-S3 LCD_CAM SPI driver (true SPI chipsets).
LCD_CLOCKLESS	ESP32-S3 LCD_CAM clockless driver (replaces misnamed I2S).
UART	ESP32 UART driver via wave8 framing.
FLEX_IO	Teensy 4.x FlexIO2 driver.
OBJECT_FLED	Teensy 4.x ObjectFLED driver.
LPUART	Teensy 4.x iMXRT1062 LPUART (inverted-TX + eDMA) clockless driver.
BIT_BANG	Portable bit-bang fallback driver.
STUB	Native/host/test stub driver.
