Function Documentation

read()

template<typename Driver >

uint16_t sbl::pot::read ( Pot &  pot, const AdcHandle &  handle, adc::SampleTime  sample_time = adc::SampleTime::Slow  )

inline

Read ADC channel and feed into Pot (EWMA + deadband)

Blocking read followed by Pot::update(). Returns the stable value.

Template Parameters

Driver

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

Parameters

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

Returns

Stable (deadbanded) value (0-65535)

Note

Not ISR-safe — wraps blocking ADC polling read

Definition at line 42 of file input.hpp.

Here is the call graph for this function:

read_dma()

uint16_t sbl::pot::read_dma ( Pot &  pot, const uint16_t *  buffer, uint8_t  channel_index  )

inline

Read from DMA scan buffer and feed into Pot.

For use with sbl::adc::start_scan(). Casts to volatile to ensure the compiler generates a real memory read (buffer updated by DMA hardware).

Parameters

pot	Pot instance to update
buffer	DMA scan buffer (from start_scan)
channel_index	Index of this channel in the scan sequence

Returns

Stable (deadbanded) value (0-65535)

Note

ISR-safe — volatile DMA buffer read, no blocking
