[esp32 support]

OK, it's nothing on the "pro" level but should get you off the ground:

https://github.com/malachi-iot/ugfx-drivers

Things to note:

1. Uses my custom and not-yet-mature framework abstraction lib
2. Uses symbolic linking and git submodules, though in your own adaptations that can be avoided
3. Look in tests/* for a couple of adaptations of uGFX gdisp demos
4. tests/* use platformio, but with a little work one should be able to use ESP-IDF makefiles directly with the shown code

Working on turning the code into a presentable example

It's a little fiddly and I'm hoping to simplify it.  Will post here with updates

Solved by this 

 

Beware, things are still as the forum says, the readme.md of gdisp basic sample is outdated.  Refer to the linked thread instead

[esp32 + SSD1306]

Hey everyone, I am a newcomer to uGFX.  But not a newcomer to programming

I believe I nearly have uGFX running on an ESP32 with an I2C SSD1306.  A proper "uGFX" branding appears on display init.  But then, after that, screen goes black and remains black no matter what I've tried.  Running at 100Khz, just to ensure things work.  I2C APIs not reporting any errors.  Any ideas?  Thanks in advance!

EDIT: Running the "basic" gdisp code, modified slightly:

const char tag[] = "displayTask2";

// Yanking this in direct from "basic" demo for gdisp
void displayTask2(void *pvParameters)
{
	coord_t		width, height;
	coord_t		i, j;

    ESP_LOGD(tag, "Display init start");

    // Initialize and clear the display
    gfxInit();

    ESP_LOGD(tag, "Display init done");

    // Get the screen size
    width = gdispGetWidth();
    height = gdispGetHeight();

    // Code Here
	gdispDrawBox(10, 10, width/2, height/2, White);
    gdispFillArea(width/2, height/2, width/2-10, height/2-10, White);
    gdispDrawLine(5, 30, width-50, height-40, White);

    while(TRUE) {
        for(i = 5, j = 0; i < width && j < height; i += 7, j += i/20)
            gdispDrawPixel(i, j, White);

    	gfxSleepMilliseconds(5000);
        gdispClear(Black);

        ESP_LOGI(tag, "Display redraw");
    }       
}
