okay so bestie, welcome to the tsl2772_get_lux(9) page from the Kernel API Manual β yes it's a section 9 manpage, yes we're reading it for fun, no I will not be taking questions π
πΈ NAME πΈ
tsl2772_get_lux β literally reads the ambient light and does the math to hand you the current lux value β¨
π¦ SYNOPSIS π¦
int tsl2772_get_lux (struct iio_dev *indio_dev);
π ARGUMENTS π
indio_devβ a pointer to the IIO device π«Ά that's it, that's the whole argument list, she's low maintenance
π DESCRIPTION π
so here's the vibe π β the raw ch0 and ch1 values of the ambient light that got sensed during the last integration cycle get read straight off the device. periodt, that's step one.
then the raw values get multiplied by a device-specific scale factor, and divided by the integration time and the device gain. the way that math eats π₯
and it doesn't stop there β the code supports multiple lux equations through the lux table coefficients, because one equation is never enough, obviously. a lux gain trim gets applied to each lux equation, and then the maximum lux within the interval 0..65535 is selected. the winner takes it all, main character energy only π
ngl this whole thing is giving "trust the process" β read, scale, divide, trim, pick the max. iconic behavior, no cap π
