Hello,
In // , I'm also working on a project with ESP32 TTGO T display.
To be able to read the battery level voltage, I need to enable the IO14 , Thx to add this IO available on the Component
IO14 on ESP32 TTGO display not available to read voltage

Hello,
Many thanks for letting us know. I've pushed an update to the library update system that should make this pin available for you now.

Re: IO14 on ESP32 TTGO display not available to read voltage
Dear ben, thx for your prompt reply and modification
Please add the IO0 and IO35 to be able to use the 2 push buttons. Could you also change the gLCD IO to port A like on the pictures (to be able to start new project with the good GLCD pin setup) X offset and Y offset are not good and need to add offset like you can see on the picture. Could you check why please. Thx

Hello,
Pins 0 and 35 added for you now.
The X and Y offset are just down to how the rows/columns of the display has been wired to the driver IC. Is it working correctly with those settings?

Re: IO14 on ESP32 TTGO display not available to read voltage
Hi,
GPIO0 is working well but Pin35 is not working, I checked the complete Portb.
GPIO35 is working on simulation but not on ESP32 TTGO display Pin0 and 35 are not available on INT too
Could you check ASAP. thx
Code: Select all

Re: IO14 on ESP32 TTGO display not available to read voltage
Hello Seb,
Sorry for the delay in getting back to you.
Are you using pin 25 as an input or an output? The pin is input only on the ESP device i'm afraid if you're trying to use as an output.
There's a nice table here showing the pin capabilities.

I'll have a look at the INT pin and see if that is missing options.

Re: IO14 on ESP32 TTGO display not available to read voltage
Dear Ben,
yesterday, I did a test on simple program of the input GPIO0 and GPIO35 on 3 ways.
1st way with INT GPIO0 and INT GPIO35
Both are working well
Video below 2nd way with GPIO0 and GPIO35 as input buttons.
GPIO0 active low and GPIO35 active high
GPIO0 is working well state change when button is pushed
GPIO35 is not working no state changes
Video below 3rd way with GPIO0 and GPIO35 as input buttons
GPIO0 active low and GPIO35 active low
GPIO0 is working well state change when button is pushed
GPIO35 is not working well, the state change (screen refreshed) at every prog loop. it's not same as GPIO0 with active low.
Video below Prog file in the next message
Could you check the FCD file or others file to try to find what happen.
thx
Seb
