Crowpanel 7" - examples projects won't compile

CurryKitten · June 4

I've been struggling to get anything useful going on my Crowpanel... as soon as I try anything do do with touch or having graphics. I've tried various examples with different errors, but lets take the example from this page https://www.elecrow.com/wiki/CrowPanel_ESP32_Terminal_RGB_with_Arduino_IDE.html?srsltid=AfmBOoo-YkCFT0QWGa6RqqLdJwG-VCta26r2sTdbfbqdhYuCtWEg5wP4#example-1-switch-color-screen
I've downloaded the project, opened it in Arduino IDE 2.3.6, installed the library package, and downgraded my esp32 package in the boards manager to 2.0.14... I can't remember if it tells me to do that in this example of others. It's hard to tell as I'm losing track of the amount of examples I've tried along with the will to live

So in that particular example we're hit by the error

     void begin(uint8_t _addr);
          ^~~~~

it feels like I must be doing something fundamentally wrong to not be able to get this compiled, but I can't tell what!

Hello there,
Apologies if I was in the wrong code, I thnk I ended up there after trying everything else! Ok so I went to this page https://www.elecrow.com/wiki/ESP32_Display_7.0-inch_HMI_Arduino_Tutorial.html and downloaded the example code from this link https://www.elecrow.com/download/product/CrowPanel/ESP32-HMI/7.0-DIS08070H/Arduino_Tutorial/example_code.zip I downloaded the libraries from here https://www.elecrow.com/download/product/CrowPanel/ESP32-HMI/7.0-DIS08070H/Arduino_Tutorial/libraries.zip and unzipped and placed them into my Arduino/libraries folder. I pretty much get the same error:

I can see GT911 in the library files I downloaded in the folder gt911-arduino-main and in the TAMC_GT911.cppm the begin method does indeed want a parameter:

void TAMC_GT911::begin(uint8_t _addr) {
  addr = _addr;
  Wire.begin(pinSda, pinScl);
  reset();
}

Dear CurryKitten,

Which esp32 version did you install? Please makesure to install esp32 version 2.0.14/2.0.15. Installing other versions will cause errors. Please refer to this link for installation instructions:
