[h2]
Since SuRG is a sun-lit display, is it possible to still use it in environments where ambient lighting is very low?
[/h2]Yes, SuRG comes with an optional, PWM-controlled frontlight that can be used in environments where there is little to no ambient lighting. This frontlight can be controlled from within software using the “setBackLightPWM(uint8_t pwmLevel)” function, passing a value from 0 (off) to 255 (max brightness). Bear in mind however the frontlight increases its power consumption:
-
1.4mA (Idle, no Frontlight)
2.6mA (Idle, w/ Touch, no Frontlight)
24mA (Active, no Frontlight)
61mA (Active, with Frontlight)
