Hi all, I'm trying out the t-display touch; which works pretty well - although it's a bit fussy about libraries! - I'm trying to find out what GPIO pins I can use; on the product website, it shows the pinout for the board, but most of the pins are labelled "touch", but it doesn't say if that means they are being used by the touch panel - has anyone else used one of these boards? Are there any spare GPIO pins - Ideally SPI pins.
Your topic was MOVED to its current forum category which is more appropriate than the original as it has nothing to do with release 2.0 of the IDE
what exact is a "t-display touch" ?
What exact type of microcontroller are you using?
help us to help you. You have to provide much more specific information. Best thing would be to post the exact type and links to the datasheets of all components that you are using.
best regards Stefan
Hi Stefen, it's one of these - T-Display-S3 – LILYGO® - it uses the ESP32 processor. The pin out shows a lot of pins labelled "touch", I don't know if they've been used for the touch panel built in or if they're available for me to use.

You mean this pinout?
They seem to use a different IO-pin-setting than most other ESP32-boards
The product page links to this GitHub repository with more techical information and examples
best regards Stefan
I think I'll have to modify the example to display the pins being used for the touch and the display, fingers crossed that the SPI and 3 other pins are available.
