CrowPanel 2.1" round with rotary encoder Example sketch too large (189% of available space)

bbroerman — Mon, 01 Dec 2025 23:21:17 +0000

Hi,
I am trying to complile and run the included example (RotaryScreen_2_1) for the CrowPanel 2.1inch-HMI ESP32 Rotary Display 480*480 IPS Round Touch Knob Screen in Arduino IDE 1.8.19, using the included libraries, and included SquareLine UI files. I've used similar screens before, and created my own SquareLine UIs in the past. This one, however, will not compile. When I try to verify the project, it says that the sketch is too large (Sketch uses 5951649 bytes (189%) of program storage space. Maximum is 3145728 bytes)
I even tried removing unneeded code (LED bar and all wifi code) and removed some of the un-used images). No clue how to get this to compile and run... How did Elecrow get their example built??

I set up the board (under the tools menu) exactly as described in the instructions in the GitHub repo.

LVGL Version Issues – Errors in Provided Code for 5-Inch Display

Hello,

I recently purchased the CrowPanel ESP32 5-inch display and have been trying to run the example code provided for LVGL and SquareLine Studio in the following sources:

GitHub Tutorial Code (from YouTube, I practice the code by order)
Demo Code from Elecrow Wiki

However, both versions resulted in numerous compilation errors, most of which seem to be caused by outdated LVGL commands that are no longer recognized in the latest LVGL library.

I also tried using the corresponding LVGL version specified for the demo code on the wiki, but despite successfully compiling, the screen remains empty with no visible output.

Could you provide an updated version of the code that is compatible with the current LVGL release? If not, could you clarify which LVGL version is required for the provided code to function correctly?

Thanks in advance for your help!

Elecrow HMI Board can be selected on Squareline Studio!

With the new version of SquareLine Studio, you can directly select the Elecrow CrowPanel HMI board when creating a project, which makes it easier for you to develop CrowPanel!

ESP-IDF (NOT Arduino) Squareline / LVGL example for ESP32-S3 5.0" display?

ToddZ — Thu, 20 Feb 2025 20:52:32 +0000

Does anyone anywhere have an example of Squareline / LVGL working under ESP-IDF (NOT Arduino) for the Crowpanel 5" display? (Or any ESP32-S3 Elecrow display?). All the examples keep using Arduino which won't work for production delivery. Any help is appreciated.. Elecrow's links do not have anything that actually compiles or functions under ESP-IDF (VS Code or PlatformIO).
