Hi,
Is it possible to change the Adafruit Circuit Playground TFT Gizmo screen intensity?
Thanks

Do you mean brightness? If so, the backlight can be controlled via the LITE pin:

"LITE - this is an input used to externally control the backlight. This is connected to A3."
Can you please provide more information about how to control it.

[old post, sorry, but . . .] I have not played with this myself (but just yesterday, I bought a Gizmo), I assume they mean you can control the brightness of the Gizmo screen with PWM from the ckt playground xpress to control the backLite of the Gizmo.
from adafruit's Ckt Playgrnd Xpress page, it says:
from adafruit's Ckt Playgrnd Xpress page, it says:
I (again, I assume), in your program, you would set D10 pin (labeled A3) as an analog out (PWM), and as you increase/decrease the Duty Cycle of the PWM the Gizmo screen's backLite will brighten/darken.A3 / D10 - This pin can be digital I/O, or analog Input. This pin has PWM output and can be capacitive touch sensor

Yep, you'd use PWM. The exact code for this would depend on how the Circuit Playground is being programmed. Arduino, CircuitPython, etc.
