Answer:
When the power comes back, the GrowCube can remember the programming and continue watering on schedule.

I recently purchased the Elecrow 5" HMI (DIS0750h) in hopes to build my own resource monitor screen for myself.

But I have watch several of the Tutorials and downloaded the lessons and the examples for this specific screen. But i have YET to get a single Arduino Sketch to properly compile.

I have tried reverting the LVGL to 8.3.11 from the newest 9.4.0, and it does change the errors but still no luck.
The errors seem to be declaration of function errors...

I have even TOTALLY uninstalled Arduino and reinstalled... including scrubbing all libraries. presently only running the libraries that are required, but still it won't compile. The latest attempt is with the "crowpanel-esp32-5.0" ino. and i get this error.
Compilation error: implicit declaration of function 'lv_mem_alloc'; did you mean 'lv_realloc'? [-Wimplicit-function-declaration]

Can anyone please help i feel like im running around in circles...
Thanks in advance..
Ettill

]]> GrowCube moisture sensor calibration https://forum.elecrow.com/index.php?p=/discussion/27971/growcube-moisture-sensor-calibration Mon, 01 Dec 2025 03:15:42 +0000 Arduino & Crowduino Rocketron55 27971@/index.php?p=/discussions Just installed a GrowCube and I have a sensor which is not reading correctly. The sensor appeared to be reading very low compared to the others. 28% compared to the 58% +/- on the others. Tried cleaning the contacts at the plug and got no improvement. Read a few postings here and saw there should be a moisture reading over 90% if emersed in water. Put all of the sensors in different containers with tap water and got readings of 95%, 95%, 65% and 95%, the 65% being the sensor which reads low in soil too.
It appears one sensor is faulty, however if there were a way to calibrate the sensor it might be useable still.
I suspect the only solution to my problem will be getting a replacement sensor, how would I do that if calibration is not possible?

]]> Cannot compile with LVGL libraries crowpanel-esp32-7.0 https://forum.elecrow.com/index.php?p=/discussion/1113/cannot-compile-with-lvgl-libraries-crowpanel-esp32-7-0 Sun, 23 Feb 2025 16:00:20 +0000 Arduino & Crowduino manstt 1113@/index.php?p=/discussions Hi,
I bought a 7'' crowpanel I use ArduinoIDE 2.2. 2 to program and compile while I wanted to use the LVGL libraries.

I followed any tutorial spent hours to compile and make it work, of course the Hello World works, but I wanted to use those libraries to create a decent graphics for my project.
Any compilation with this panel fails, only some projects without lvgl work, I'm really exhausted by the thousand compilations with always the same error result and it doesn't continue as indicated in the elecrow wiki:

I followed this link:

https://www.elecrow.com/wiki/esp32-display-702727-intelligent-touch-screen-wi-fi26ble-800480-hmi-display.html#arduino-ide

https://www.elecrow.com/download/product/CrowPanel/ESP32-HMI/7.0-DIS08070H/Arduino_Tutorial/Arduino_Tutorial_70.zip

I added the libraries contained in the zip but this is the compiler result:

please advice
