No Touchscreen + expander: Compilation error

[rolloo]

Hello,
I am trying to build an example for Adafruit Qualia ESP32-S3 + Round RGB TTL TFT Display - 4" 720x720 - No Touchscreen

• Compilation error: 'ESP_PANEL_TOUCH_BUS_HOST' was not declared in this scope

ESP_Panel_Board_Custom.h

#define ESP_PANEL_USE_TOUCH             (0) 
#define ESP_PANEL_USE_EXPANDER          (1)

Hi @rolloo,

Sorry, there's a bug in the library. When setting up the expander's host, it should use the macro ESP_PANEL_EXPANDER_HOST_ID instead of ESP_PANEL_TOUCH_BUS_HOST.

The PR fixes this problem. Can you assist me in testing it?

Hi @Lzw655

😂 Sorry, the macro should be ESP_PANEL_EXPANDER_HOST. Fixed in the new commit, please try again.
