Great resource! I am working my way through Learn LVGL, and it has been very good to this point. However, I cannot find the WiFiScan Example program described in Module1.l6, Testing the Installation. Did I miss something? I have the IDE installed and it connects to the CYD just fine.

Hi.
Make sure you have an ESP32 board selected in Tools > Board.
Then, the examples specific for the ESP32 will show up.
Regards,
Sara

That is the strange thing. I do have the ESP32 Dev Module selected, but the WiFiScan does not show up. A search through all of the Arduino files fails to find it. What package did I fail to load? I have another program that runs just fine on the CYD.

Hi again.
Can you see other ESP32-specific examples under the Examples folder?

Johnny Russell answered 9 months ago
There is a list of examples, but not what I expected. It show 11 categories:
01.Basics
02.Digital
03.Analog
04.Communication
05.Control
06.Sensors
07.Display
08.Strings
09.USB
10.StarterKit_BasicKit
11.ArduinoISP

Hi.
It seems your Arduino IDE is not loading the ESP32 examples.
I think it’s a bug in your IDE.
You can find the wifiscan example here: https://github.com/espressif/arduino-esp32/blob/master/libraries/WiFi/examples/WiFiScan/WiFiScan.ino

Thanks Sara,
That link is just what I needed. It seems some package is still missing, but I can work on that later.

Hello Sara,
I just went to Library Management in the Arduino IDE, searched for and installed “WiFI”. Now, there are about a hundred new entries in example under the 11 I had before. WiFiScan is one of them.
Just lettin you know.
