Function Documentation

◆ initThreshold()

auto initThreshold ( const bool lower )

constexpr

set default threshold at compile time so the variable can be read-only

Parameters

lower True to set the lower threshold, false for higher

Returns: the corresponding threshold

Definition at line 46 of file processing.cpp.

◆ printParamsForSelectedOutputMode()

void printParamsForSelectedOutputMode ( )

Print the settings used for the selected output mode.

This function displays the relevant configuration parameters for the currently selected output mode. It provides details about the energy bucket capacity, thresholds, and mode-specific settings.

For the "normal" mode, it displays the energy bucket capacity and thresholds.
For the "anti-flicker" mode, it also displays the offset of energy thresholds.
