Any suggestions on how I could link in the actual source files, so I could add a few printf to determine whats going in.
Worth noting that I'm getting exactly the same error, when I did my own config for a Sutton ESP32-4827S043R so I suspect that the issue is in my VisualStudio / PlatformIO configuration some where (ie wrong library versions).

So any suggestions on where I should be looking ?

Quick update.
Eventually found the Ardunio WiFi library and source in my .platformIO folder (Linux User)
./packages/framework-arduinoespressif32/libraries/WiFi/src/WiFiUdp.cpp

A few log_e statements later, it was obvious that it the issue was related to an uninitialised DNS server call
void DNSServer::processNextRequest()

that was being called from below, which I commented out (dnsServer.processNextRequest()) ) and the error has gone, but the functionality of the device via the HTTP server, seems to be working.

IRAM_ATTR void httpLoop(void)
{
    #if(HASP_USE_CAPTIVE_PORTAL > 0) && (HASP_USE_WIFI > 0)

   // log_e("DMD Calling DNSServer processNextRequest");

   // dnsServer.processNextRequest();    
   #endif
    webServer.handleClient();
 }

Now I just have to work out my I don't have anything displayed on the touch screen.

After a lot of trail and error, I believe I found a solution and I now have both the panel and touch screen working on the Elecrow 7inch 800x480 TFT (WZ8048C070).
I had to switch to the LovyanGFX and used the parameters from this post :
https://forum.elecrow.com/discussion/473/lovyangfx-settings-for-7-display

So the custom ini file that is working (both display & touch) is 👍

Hi @DaveDuncanson, thank you so much for this post. I'm struggling with this Elecrow 7" screen and came across your post, which helped me get the display working but not the touch. I've been able to upload my .ino and it displays my home screen, but I can't get the touch to work with the UI. I've tried changing the 4x touch pins to match what you use, able to get the GT911 touch example to work, and I can even get the screen to display my home screen of the UI while having the Serial Monitor to print locations that I touch on the screen, but I can't get those touches to register and make events on the screen happen.

Any idea what I'm missing here?

Hi - I also had issues getting the touch screen working, post getting the display to present and long story short, I had to use the LGFX_TOUCH library instead of the GFx library to get it operating via the -D HASP_USE_LGFX_TOUCH=1

Below are all of the touch settings that I used.

; Touch Settings
-D HASP_USE_LGFX_TOUCH=1
-D TOUCH_WIDTH=800
-D TOUCH_HEIGHT=480

Thank you! Can you explain what you mean by "via the -D HASP_USE_LGFX_TOUCH=1" - how can I do that? I should be able to figure out adding the library and working it in to the code.
I can get this squareline studio file to display, and I can even get touch points to register if I add a ts.read() line to the loop, but for some reason those touches don't seem to want to trigger the UI events.
Thank you again for your help!

Hi - The above build flag (-D -D HASP_USE_LGFX_TOUCH=1) is for the OpenHASP v0.7rc3 build.
So assuming you did something similar, you should have setup an enviroment for the specific build in the user_setups folder.
Below is a link to a private repo, where I am storing the configuration changes. So the -D goes into the Build Flags section and the required library is already part of the OpenHASP build.

But I did notice that you mentioned SquareLine which isn't part of the OpenHASP build, instead there is a designer feature built into OpenHASP (One of many reasons that I like it).

BTW. I have also been involved in another forum (ArdunioGFX) where we were getting the settings right for the elecrow 7" 800x480 and my personal view is that this display is pushing the bandwidth limits of the ESP32-S3 bus, because there is is some test code, that does put the display under pressure, but after a few minutes the display goes blank, but code continues to run and then again after 30 sec or so, the display comes back.
Not 100% sure, but the HW parameters have been checked several times and the test code looks solid and relatively simple.

The discussion can be found here :

Thanks Dave, I appreciate your reply and all the info. After picking through all of that for a couple of hours, I'm now getting the display to show up again, this time using the LovyanGFX, but still having the problem with the touch! How frustrating.

Yes, I'm using Squareline Studio and Arduino IDE because I am still quite a beginner, hence my questions... haven't ever heard of OpenHASP until today, but I will look into it!

Do you think there's a way for me to get this working with Squareline Studio and the IDE? I feel like I'm so close, but there is some major touch functionality missing.

@DaveDuncanson
with your settings and openHASP v0.7rc8, I've been using Elecrow 7 inch for 1 month and it works really well.
Just a little long loading times at boot, if you use several pages.

In the meantime I bought a Sunton ESP32-8048S050C, but it has WiFi problems which is not stable, as you had during your tests with the Elecrow.

I just wanted to thank you @DaveDuncanson ... I picked up a couple of the Elecrow 7" (WZ8048C070) to play around with and I managed to get OpenHASP working, both touch and the screen seem to be doing what they are supposed to do. I tried out a couple of examples and it all works. Thank you for this!

Has anyone had an issue where you have to turn the upload speed down to 115200? It takes forever to download at that speed! I'm on macOS 14.2.1 if that matters.

Thanks @DaveDuncanson for the parameters! Saved me a bunch of time trying to figure it out.

@DaveDuncanson Is this still working well for you? I'm finding that my device freezes at startup and sometimes freezes and won't respond to touch and won't update.

Hi - I haven't experienced the above with the OpenHASP build, but I have seen these same issues when I was playing around with the ArdunioGFX library and my guess at the time (highlight guess), was that the higher resolution display data transfer needs were starting to push the limits of the ESP32 & bus transfer rates and limits. Without a logic analyser, there was no way for me to confirm or not. The reason that I suspected it was a H/W limitations is that one of the forum members had developed some graphical test code for the ArdunioGFX library and we both experienced the same issues in that it would run fine for around a minute, then the display updates would stop (But code was still running fine) and then start again out of the blue. The code also had occasionally long delays on startup as well.

The link to this on the ArdunioGFX forum is :
moononournation/Arduino_GFX#367 (reply in thread)

But I do need to highlight that I never experienced theses issues with the OpenHasp build and most likely because typical UI design doesn't require a lot of screen updates, unlike the test code.

Thanks! I did crank down the debug level and removed the syslog server and it is performing better. I'll keep testing to see if I have more problems.

I'm still looking for the best behaved device that can run off (and charge a battery); the Elecrow apparently won't charge a battery.
