Function Documentation

◆ write() [1/2]

template<typename Driver >

void sbl::led::write	(	const RgbLed &	led,
		const GpioHandle &	r,
		const GpioHandle &	g,
		const GpioHandle &	b
	)

inline

Write RgbLed state to GPIO pins (bang-bang)

Reads the LED's current state and writes each channel to its GPIO pin. Duty values > 0 are treated as ON. Gpio::write() handles active_low.

Template Parameters

Driver GPIO driver type (e.g., sbl::driver::Gpio)

Parameters

led	RGB LED instance to read state from
r	GPIO handle for red channel
g	GPIO handle for green channel
b	GPIO handle for blue channel

Note: ISR-safe — three GPIO register writes

Definition at line 48 of file output.hpp.

Here is the call graph for this function:

◆ write() [2/2]

template<typename Driver >

void sbl::led::write	(	const RgbLed &	led,
		uint8_t	r_ch,
		uint8_t	g_ch,
		uint8_t	b_ch
	)

inline

Write RgbLed state via SoftPwm channels (8-bit BCM)

Pushes per-channel duty cycles to the BCM engine. The Driver must provide set_duty(uint8_t channel, uint8_t duty).
