Build problems "Gdeh0213b73.h" #59

Closed AleshR closed 2 years ago

AleshR commented 2 years ago

Hi, i have problem with building example for Gdeh0213b73.

Source:

#include <stdio.h>
#include <gdeh0213b73.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"

// Two lines to start IO and instantiate your model
EpdSpi io;
Gdeh0213b73 display(io);

extern "C"
{
   void app_main();
}

void app_main(void) {
   display.init(true);
   display.setRotation(0); 
   display.println("Hello world");
   // Print a 2 pix line
   for (int i = 0; i < display.width(); i++) {
     display.drawPixel(i,10,EPD_BLACK);
     display.drawPixel(i,11,EPD_BLACK);
   }
   // Discover more of the geometrical functions of Adafruit GFX typing  display.*
}

Also i updated sdkconfig for TTGO-t5

cp ttgo-t5-sdkconfig ../sdkconfig

and

CMakeList.txt SRCS "demos/gdeh0213b74_test.cpp"

After idf.py build i get errors like this:

Now it takes me about two days to debug and i have no ideas why it's not working. Every hint or ideas will be helpful. Thanks!

I think CMakeLists is not including that class:

    # Pending for more testing:
    #"models/gdeh0213b73.cpp"

Try to uncomment that and build again. When you see this kind of "vtable" errors is because the compiler is not finding the class.
