ssd1351 Library Brightness
Hello! I have a 1.5" color OLED display, and would like to dim the display or set it to a brightness with something like tft.setBrightness(255); is this possible? Thanks!

Sorry, there's no overall brightness control for the OLED.

Bummer. How come there is for the .96" monochrome OLED and not this one?

Re: ssd1351 Library Brightness
Found a f=different library that does this -
The SSD1351 controller in the OLED128 supports user-programmable pixel intensities via the "grayscale table". The "grayscale table" also determines gamma.
FTOLED supports three default pixel intensity levels:
setDefaultGrayscaleTable();
setBrightGrayscaleTable();
setDimGrayscaleTable();
Calling setBrightGrayscaleTable() or setDimGrayscaleTable() will result in a display that is slightly brighter or somewhat dimmer than the default.
I'll use this FTOLED Library instead.

Re: ssd1351 Library Brightness
We've found that those sorts of "dimming" operations don't really make much of a difference in brightness.

Hi @Thetinkerer @ Adafruit_Support
Is it possible (or) is it ok to use FTOLED Library from freetronics for Adafruit ssd1351 ?

Re: ssd1351 Library Brightness
I'm not familiar with that library. If it works, then there's not reason why you can't use it.

Re: ssd1351 Library Brightness
Hi vena, have you had any success with the FTOLED Library from freetronics to control the brightness of the Adafruit ssd1351 OLED?
I am struggling with it :(
