set_power_scaling_exponent()

void set_power_scaling_exponent

(

float

exponent

)

Set a non-linear brightness-to-power response exponent.

Parameters

exponent

1.0 = linear (default), values below 1.0 model higher-than-linear power draw at mid brightness, values above 1.0 model lower-than-linear draw

Note

Convenience wrapper: equivalent to setting model.exponent and calling set_power_model. Prefer set_power_model(PowerModelRGB{..., e}) to configure channel weights and response in one step.

This only affects power estimation and limiting, not rendered LED brightness.

exponent <= 0 or values within 1e-4 of 1.0 fall back to linear (identity tables) rather than rebuilding with a degenerate curve.

Only enabled on platforms where SKETCH_HAS_LARGE_MEMORY==1. Smaller-memory targets keep the legacy linear behavior and ignore this setting.
