Adding new 7" RGB display ESP32 EA7013

[eagl1]

Hi,

I received this ESP32-EA7013 display from Aliexpreess, I tried to match its settings with the similar RGB display ESP32-8048S043C, as I contacted the manufacturing source:

https://www.eya-display.com/ea7013-s3/

And I asked them for resource files and they gave me the schematic, general manual for the display and ESP-IDF code.

They even didn't tell me what driver IC the display is using and they told me becuase it's RGB display it doesn't need configuration initialization commnads, but from the schematic it's similar to the one used in ESP32-8048S043C.

Now in your platformio, how to copy another board package and edited it to fit the display ?

Hi eagl,

Looks like a nice display! I assume https://www.aliexpress.com/item/1005006484114641.html.

It is preinstalled with micro-python, an esp32-s3, tn panel, however at first glance I could not find more specifications/schematics/graphics driver. Adding this board should then (if there is no new display driver required) limited to adding a definition file.

You could just take the ESP32-8048S043C.json and copy this to ESP32-EA7013.json and do some testing in there. Remember to rebuild the library (remove in .pio directory) after making changes to the definitions.

Goog luck and I can add the definition if it is working!

Can you attach the specifications to make a better assessment?

To me I got it for half the price in the Aliexpress link you provided, and shipped to me to Saudi Arabia.

Yes, I got it to work first in the ESP-IDF, then I copied the pin assignment to the Arduino code and it worked.

One time the module didn't work and also didn't have boot button, so I had to pull IO0 to GND manually and it worked and I was able to reprogram it.

The attached files are all I got from the seller. I think it's very similar to the yellow 7" on Aliexpress.

OK, I got the necessary settings to get it to work on Arduino. Based on GFX_Library_for_Arduino-1.4.x:

1. Install ESP32 board manager from espriff 2.0.17. If you want to work with ESP32_Display_Panel-master then ESP32 3.0.X board package should work.
2. Enable PSRAM OPI.
3. CH340 may not be important but CH340 2019 version worked with me.
4. Maybe you might need to press boot button maybe at least once, in my case I must pull IO0 to GND manaully.

This also will work with ESP32_8048S043 display too.

These the pin settings from ESP-IDF:

Hi Eagl1,

I made a definition for the board: https://github.com/rzeldent/platformio-espressif32-sunton/blob/ea7013/esp32-EA7013S3TN.json

If you put this board definition (or do a submodule on the ea7013 branch from https://github.com/rzeldent/platformio-espressif32-sunton) you can use it.

The settings for the display are in there but do not known the display timings. e.g. TIMINGS_HSYNC_PULSE_WIDTH etc... So do not expect it to work. However, you can modify the values there and recompile and tinker a bit. I added the speaker but the touch and TF also need to be defined. As I do not own the board it is hard to help but at least you have a starting point!

Good luck and let me know about your progress!

I wish I posted the Arduino ESP32RGGBPanel object, it has the other necessary settings:

Arduino_ESP32RGBPanel *rgbpanel = new Arduino_ESP32RGBPanel(
    5 /* DE */, 2 /* VSYNC */, 4 /* HSYNC */, 6 /* PCLK */,
    7 /* R0 */, 15 /* R1 */, 16 /* R2 */, 8 /* R3 */, 3 /* R4 */,
    46 /* G0 */, 9 /* G1 */, 10 /* G2 */, 11 /* G3 */, 12 /* G4 */, 13 /* G5 */,
    14 /* B0 */, 21 /* B1 */, 47 /* B2 */, 48 /* B3 */, 45 /* B4 */,    

    0 /* hsync_polarity */, 10 /* hsync_front_porch */, 16 /* hsync_pulse_width */, 32 /* hsync_back_porch */,
    0 /* vsync_polarity */, 15 /* vsync_front_porch */, 3 /* vsync_pulse_width */, 12 /* vsync_back_porch */,
    1 /* pclk_active_neg */, 15000000 /* prefer_speed */);

Anyway I''m working on it.

I compiled it and this is the result:

The ones succeeded are the ones I have except the first one and esp32-EA7013.

I think I will delete it and download a new one.

The demo application but change the sub module reference to the branch ea7013

You mean I comment the board I don't want to uncomment the board I want ?

[eagl1]

Is the esp32-1732S019C, required as a dependency ?

Because when I launch VS code I get this message:

Resolving esp32-1732S019C dependencies...
UnknownBoard: Unknown board ID 'esp32-1732S019C'

As it clear I'm commenting all the boards except esp32-8048S043C. Am I on the right path ?

I still don't know how to compile the project at this point ?
