Function Documentation

read()

template<typename Driver >

void sbl::button::read ( Button &  btn, const GpioHandle &  handle  )

inline

Read GPIO pin and feed into Button (debounce + edge detection)

Gpio::read() returns logical value (active_low handled by driver), so Button doesn't need inversion logic.

Template Parameters

Driver

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

Parameters

btn	Button instance to update
handle	GPIO handle for the button pin

Note

ISR-safe — single GPIO register read
