ESP32_Display_Panel example project not comipiling

[wavejaco]

Hi everyone.

I am trying to build the "PanelTest" project under "Examples->ESP32_Display_Panel", but with no luck.

I have performed all the configuration changes as outlined in the PanelTest.ino file, both for the supported and custom board versions.

When compiling, I get the following error:
PanelTest:46:1: error: 'ESP_Panel' does not name a type; did you mean 'ESP_PanelLcd'?
46 | ESP_Panel *panel = nullptr;
| ^~~~~~~~~
| ESP_PanelLcd
C:\Users\User\Documents\Arduino\libraries\ESP32_Display_Panel\examples\Panel\PanelTest\PanelTest.ino: In function 'void setup()':
PanelTest:74:5: error: 'panel' was not declared in this scope
74 | panel = new ESP_Panel();
| ^~~~~
PanelTest:74:17: error: expected type-specifier before 'ESP_Panel'
74 | panel = new ESP_Panel();
| ^~~~~~~~~


I have even used the custom board setup in an attempt to avoid the issue (as documented in https://github.com/esp-arduino-libs/ESP ... /issues/26, but with the same result.

As this comes directly from the Waveshare at https://www.waveshare.com/wiki/ESP32-S3-Touch-LCD-4.3, one would expect that it would reliably build after following the relevant instructions.

How can this be resolved?

Thank you very much for your consideration in this issue.

What version of arduino-esp32 are you running? I would recommend using 2.0.17. The API has changed in v3.0.x.
