Some time ago i joined to M5Stack users and try to adapt my arduino chess program. Absence of touch screen disappointed a little, but finally i decide processor to suggest possible moves for choosing with buttons.

Just save previous displayed value in global variable, before display compare with saved, and display only if they differs.
In this project i used TEMT6000 Light Sensor, connected to 3.3v pin and ground pin of m5Stack, and signal to GPIO 35 (ADC). Measures light uniformity and determines, if present, PWM frequency (50-1000 Hz) and ligth falloff. Buttons A and C used to change smoothing coefficient to eliminate high frequency noise.
Link to sketch available lower.

@m5dude Thanks!
Sorry about comments absence in code - they was on local language, and dropped automatically when downloading. Code optimisations was only on chess engine, other parts made more rudely.
@jimit Hi!
Thanks. Looks like performance gain corresponds to growing frequency of processor.
Of course you may add it to your github list.
