set_power_model() [1/3]

void set_power_model

(

const PowerModelRGB &

model

)

Set custom RGB LED power consumption model.

Parameters

model

RGB power consumption model. The model's exponent field drives the brightness-to-power response curve used by estimation and limiting; pass PowerModelRGB(r, g, b, d, e) to set channel weights + response curve in a single call.

Note

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