SOLVED: TRIAC delayed-trigger compensation routine

[f4lc0n-asm]

Hello,

if a TRIAC delay is decreased linearly, the output power delivered to a resistive load does not increase linearly. I thus developed the following compensation routine:
Input: Relative power (0: off up to 1: full power)
Output: Linearized relative TRIAC trigger delay (0: start of half sine wave up to 1: end of half sine wave, 1 when input < 0, 0 when input > 1, NaN when input is NaN)
Relative error of power delivered to the resistive load: < 1e-5
