hallo i have a problem whit the ESP32-S3 and working whit the Arduino GFX Library.

  • error: 'gfx' was not declared in this scope.

Compilation error: no matching function for call to 'Arduino_ESP32S2PAR8Q::Arduino_ESP32S2PAR8Q(int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int)'

Where you got this code from?
Arduino_ESP32S2PAR8Q require only 12 pins in constructor, but you try to install 23

The code came from
[ESP32-S3 Parallel TFT with Touch 7.0" 1024600 800480 | Makerfabs]
makerfabs
Github

i type it in the Arduino IDE , and used the example from the library

Your links mean nothing.
Please be specific about where you got this code.

5

You got something mixed up - you use a class for 8bit parallel connections, but pins of 16 bit.

Hy B707,

i re-buffer the setup of the IDE of Arduino ,
and is building now .

but i still don't get a window to show on the display.
the CVS or display electronic cart .

it tink i cod the control bus rong
