New project, a small wall display to control Domoticz using CYD (Cheap ESP32 touchscreen)

[palnic]

I have updated the code to "trying" to support your device (just comment/uncomment in platformio.ini file), I m using pin from here https://github.com/Smanar/CYD-Domoticz-Remote/issues/2
The code compile, but I think your device don't use the same driver, I m using DILI9341_2_DRIVER but I think you need to use DILI9341_DRIVER, problem with this driver you will miss some declaration.

I m searching a working project with this device, and you will probably need the same lib than @kniazio (lovyanGFX), but I prefer make try first with TFT_eSPI

Edit:
Have found a new configuration

Code: Select all

      "-DILI9341_DRIVER=1",
      "-DESP32_2432S024C",

This one is compiling, I don't think the touch will work but I think the display will be fine.
This last change is not yet on the github.

Thanks a lot. Will try today

[palnic]

Thanks again! As you said it is compiling now but touch doesn't work. All I can see is "Calibrate screen"

Maybe this is womething your are looking for ?

Yes exaclty, I have put this one in my list but it have somes negatives points
- the price, it's correct, but others are realy cheaper.
- Need to make a special hole in the wall, and I already have one (standard hole in my country), so I need to adapt it, for the other one, I just need to print a case, put a 230AC/5VDC alimentation in the hole, and the device behind.
-Few documentation.

But for the moment it's the better one I have found.

@palnic I based the code on this issue https://github.com/HASwitchPlate/openHASP/issues/555
But it seem the lib I m using don't support this touchpad, so need to migrate too on the LOVYANGFX.

The only working project for your device I have found is this one https://github.com/elik745i/ESP32-2432s024c so I will use the same config.
I have a new version using the second lib on the github, but on branch "test", I m breaking other stuff ATM so I can't send it on "master".

[palnic]

I saw the openHASP project and a few years back I tried to adopt it to Domoticz. Unfortunately my programming skills is not good enough, I am electrical engineer, and I wasn't able finish this job. I still have case from the HASP and ESP32-2432s024c wilt fit almost perfectly. This is a standard case for US. It would be nice to finish this project for Domoticz

[Thorgal789]

Do you have tried the branch "test" on my github to see if this one is working ? Display and touch ?
I have updated it yesterday with the same setting than in the openHASP project ,but my driver, so I don't know the result.

[palnic]

Thanks, will try now

The sensing definitely works, the is some issue with display pictures will look into

[kniazio]

As usual, @Thorgal789 did a lot of work. The display now works very stably. All I need is additional websites for my devices

[EdwinK]

Going to try this with the CYD that I bought for my printer but is now not needed anymore.

[Thorgal789]

@palnic The field to play are

Code: Select all

      "-DTFT_WIDTH=240",
      "-DTFT_HEIGHT=320",
      "-DTFT_ROTATION=4",

On the json file and

Code: Select all

    disp_drv.hor_res = TFT_HEIGHT;
    disp_drv.ver_res = TFT_WIDTH;

in the screen_driver.cpp file, sometime we need to reverse TFT_HEIGHT and TFT_WIDTH.

If you can't success, I will try to compile the project that use your device, this action will enable/disable code, so easier to understand the good config in this "multi support" code.

@EdwinK
Take care the last code is still on the branch "test", I haven't updated the master branch yet, need to make some bench to see cpu/memory use with the new code.

Thanks. Here are my settings:
platformio.ini:
-DTFT_WIDTH=320
-DTFT_HEIGHT=240
-DTFT_ROTATION=2
screen_driver.cpp:
disp_drv.hor_res = TFT_HEIGHT;
disp_drv.ver_res = TFT_WIDTH;
Display looks perfect, but sensing doesn't work

[Thorgal789]

You need to reverve the display at 90° no ? Widgets are by defaut more longer than larger.

but sensing doesn't work

It have worked previously ? Yes else you will be blocked at calibration step.
On the platoformio.ini file

Code: Select all

-DFORCECALIBRATE=false 

Set it to "true", It's possible the previously memorised don't work with your new setting. This setting will reset the touch calibration at every restart.

(And there is a setting to reverse the touchpad too if neeeded, but harder to see, I can give you a code to see the pointer, easier to see if you need to reverse it too)

[palnic]

OK. It works now, trying to connect to Domoticz. Thanks a lot. What about cup of coffee

[Thorgal789]

Lol, for me will be soon a full diner.
Give me your last setting, 90° reversed (or you can keep it in this side, but not sure what can be the result) I will put them in my next update.

For information I m searching a way to add secondary (or more) page, will be the same than on the homepage, but not updated in real time.
And I still have a strange issue on too big json.

[palnic]

Ok, enjoy your dinner. My lunch is over, working to rotate the screen

[palnic]

Actually I am going to keep it vertically, since I want to replace some wall switch and display extra info on the screen. My settings stay the same:
platformio.ini:
-DTFT_WIDTH=320
-DTFT_HEIGHT=240
-DTFT_ROTATION=2
screen_driver.cpp:
disp_drv.hor_res = TFT_HEIGHT;
disp_drv.ver_res = TFT_WIDTH;
So far I can't connect to Domoticz, says "Failed to connect"?

[palnic]

No matter what I do, the is no connection to Domoticz. Connected to WiFi, Domoticz is ON, but can't connect display, it says "Failed to connect"

[Thorgal789]

No problem, I will update the code for the vertical support, waiting if one day I found someone that need the horizontal. But you will probably need to change the display 2*4 instead of 3*3 ?

Value to enter for connexion need to be for exemple:
- host : 192.168.1.1
- port : 8080

If it don't work

Be sure the device have its IP autorised in the Trusted Networks setting in Domoticz.

[palnic]

My Domoticz address is 192.168.0.86:8080. This is what I entered. Looks like it doesn't reset connection after if failed once.

[Thorgal789]

Looks like it doesn't reset connection after if failed once

If I m right it's memorised, but you have a button to reset it.

You can set them direclty in code in main.cpp

Code: Select all

    #if FORCE_CONFIG
        strcpy(global_config.wifiPassword, "xxxxxxxxxxxxxxxxxxx");
        strcpy(global_config.wifiSSID, "xxxxxxxxxxxxxxx");
        strcpy(global_config.ServerHost, "192.168.1.1");
        global_config.ServerPort = 8080;
        global_config.wifiConfigured = true;
        global_config.ipConfigured = true;

        const static int t[] = {37, 75, 16, 36, 28, 35, 57, 89, 45};
        for (int i=0; i<TOTAL_ICONX*TOTAL_ICONY; i++)
            global_config.ListDevices[i] = t[i];
        WriteGlobalConfig();
    #endif

If you enable FORCE_CONFIG in platformio.ini

You see nothing in domoticz log, or on device log (with serial monitor) ?
Yo have added the device IP to domoticz setting (trusted network) ?
