Battery and no display

[vautieri]

With the 3.7 VDC batt plugged in, the red led goes bright, so I know it is connected. However, when I disconnect rhe USB c, the display turns off. Do I really need to power this through the USB port for. The display?

If you are new to the LilyGO T-Display S3 I suggest you look through my GitHub repository I made as a user. https://github.com/teastainGit/LilyGO-T-display-S3-setup-and-examples Sounds like a case of: "C) Can run on USB power but not battery connector: In declarations add

define PIN_POWER_ON 15 // just before the setup and then in setup add:

pinMode(PIN_POWER_ON, OUTPUT);  //"triggers the LCD backlight, and enables battery power
digitalWrite(PIN_POWER_ON, HIGH);)  //on startup"

(LilyGO variously refers to them as "LCD power on" OR "PIN_POWER_ON")
Thanks to user RobLatour for finding this cure for the battery issue!"
