Function Documentation

◆ read()

template<typename Driver >

uint16_t sbl::cv::read	(	CvInput &	input,
		const AdcHandle &	handle,
		adc::SampleTime	sample_time = `adc::SampleTime::Slow`
	)

inline

Read ADC channel and feed into CvInput filter.

Blocking read followed by CvInput::update(). Returns the smoothed value.

Template Parameters

Driver ADC driver type (e.g., sbl::driver::Adc)

Parameters

input	CvInput instance to update
handle	ADC channel handle
sample_time	Sampling duration (default: Slow for pot sources)

Returns: Smoothed value (0–65535)

Note: Not ISR-safe — wraps blocking ADC polling read

Definition at line 42 of file input.hpp.

◆ read_dma()

uint16_t sbl::cv::read_dma	(	CvInput &	input,
		const uint16_t *	buffer,
		uint8_t	channel_index
	)

inline

Read from DMA scan buffer and feed into CvInput filter.

For use with sbl::adc::start_scan(). The DMA buffer is the abstraction boundary — no driver template needed. Casts to volatile to ensure the compiler generates a real memory read (buffer is updated by DMA hardware).
