I ordered the two options G4 and Lora (WiFi) at the same time because I might need them later.
Now I have to realize that if you order these options, certain interfaces such as RS485 are no longer possible. It's a shame that there is no indication when ordering that if you choose an option, certain interfaces will no longer be available. It would be nice if this could be added on your website.

Now I need to know which drivers I have to uninstall so that I can have the interfaces I need (2xRS485) available again. I'm still a beginner with Raspberry Pi. I'm not using G4 or Lora at the moment.

Thank you very much.

]]> 4.3 Inch HMI ESP32 Display Resolution Problem https://forum.elecrow.com/index.php?p=/discussion/804/4-3-inch-hmi-esp32-display-resolution-problem Mon, 15 Jul 2024 20:29:45 +0000 Elecrow HMI Display aliberkarad 804@/index.php?p=/discussions Have a nice day,
I am a 4.3 Inch ESP32 HMI Display user. I am following the new video training series. I hope it will be long and updateable.

I loaded the widget example from Lesson 5 and noticed something. After uploading, the resolution appeared different and the thickness of the text was different.
After upload
When the screen arrived as a brand new product, the widget demo that was installed in it offered a clearer resolution. This difference is even visible in your 4.3 inch ESP32 HMI display video.
First State
Also, the resolution is not clear in the uploads I made in other lessons. I use "LV_FONT_MONTSERRAT_14" as the font.
What do you think is the main reason? What am I missing?

Thank you for your help and comments.

]]> Compilation Error in the Arduino IDE for the CrowPanel ESP32 HMI 5.0'' https://forum.elecrow.com/index.php?p=/discussion/801/compilation-error-in-the-arduino-ide-for-the-crowpanel-esp32-hmi-5-0 Mon, 15 Jul 2024 06:01:38 +0000 Elecrow HMI Display Jessamine 801@/index.php?p=/discussions Hello everyone <3
Nowadays, I am working on a project that uses the arduino development environment 2.3.2, the ESP32 wrover module, and the crowpanel ESP32 HMI 5.0 display. I downloaded the arduino_5inch.zip file and followed the wiki's setup guide. I tried to build the HMI-5.ino sketch after copying the libraries fromArduino_5inch\Hardware-Version-1.0\libraries to `C:\Users\MyName\AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.14\libraries. But I am facing upon the compilation error There is no such file or directory for demos/lv_demos.h.
I checked that the paths are valid and that the libraries are in the right place twice. Is there anyone else who has dealt with this problem or has some advice?
I apprieciate your help thanks in advance :) :)
