Brightness on m5stickc & core gray?
-
On the m5stickc, uiflow's brightness is converted to axp.setLcdBrightness(level). This appears to be between 0 and 100, although 20 is barely visible in the dark.
The core gray doesn't have axp, but one can use lcd.setBrightness(level): This appears to be 0-255 from the doc, but realistically, it doesn't seem to matter above 25 or so. Is this documented anywhere?

Hello @dclaar
I don't think this has been documented yet - but I could be wrong.
But consider this. I have multiple M5Stack (Gray, Basic, Fire) and even with the same brightness setting the actual brightness differs visibly.
Thanks
