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

What are the reasons for this warning? I tried to move the sensor and checked the connection. It seems good.

Best regards,

Hector

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:

Download link for Android of GrowCube APP:

1.Please allow all the permission, especially Location Permission

2. After installation, firstly select Direct Connection Mode to update firmware

•  Direct Connection Mode: directly connect the device for control when there is no network outdoors.

  The mobile phone is directly connected to the wireless network sent by the device: growcube XXXX. This network is only used for communication between the device and the mobile phone, not for accessing the Internet. When the mobile phone prompts that the WiFi cannot access the network, click continue to use.

  After entering the device through the direct connection mode, you need to upgrade the firmware. After clicking the firmware to complete the upgrade, you can switch to the networking mode again. The networking is completed according to the operation, that is, the mobile phones and devices are connected to the WiFi in the home environment, that is, the WiFi in the user's home can normally access the network

3. After updating firmware, select Networking Mode to set up network configuration

Notice:

(1) Please don't use 5G network as it is currently not supported.

(2) It is no network when connect with WiFi named 'GrowCube_XXX', please switch to the APP and continue next step.
