Example compiling error: Must define USE_AIRLIFT or USE_WINC1500 before including this file.

[WieFel]

• Arduino board: Adafruit Feather M0

• Arduino IDE version (found in Arduino -> About Arduino menu): 1.8.9

• List the steps to reproduce the problem below (if possible attach a sketch or copy the sketch code in too): I am trying to compile the example adafruitio_02_pubsub for my board. I opened the example project using the Arduino IDE. The only things I modified were the IO_USERNAME, IO_KEY, WIFI_SSID and WIFI_PASS fields in the file config.h. In the main file adafruitio_02_pubsub.ino I only added the line WiFi.setPins(8,7,4,2); as the first line in the setup() function as it is done in the setup guide here: https://learn.adafruit.com/adafruit-feather-m0-wifi-atwinc1500/using-the-wifi-module#check-connections-and-version-7-7

However, when compiling the code I get the following error:

In file included from sketch/config.h:30:0,
                 from /home/felix/Arduino/adafruitio_02_pubsub/adafruitio_02_pubsub.ino:18:

   #error "Must define USE_AIRLIFT or USE_WINC1500 before including this file."
    ^
exit status 1
Error compiling for board Adafruit Feather M0.

I cannot find out what the actual problem is. With earlier versions of the Adafruit IO examples I didn't encounter any problems. All the libraries necessary for using Adafruit board with Arduino IDE (Arduino SAMD Boards, Adafruit SAMD Boards, Adafruit IO Arduino 3.2.0, WiFi101 0.16.0) are uptodate. Any suggestions?

@WieFel Uncomment the #define USE_WINC1500 at the top of your config.h file. (see here: https://github.com/adafruit/Adafruit_IO_Arduino/blob/master/examples/adafruitio_02_pubsub/config.h#L27)

Are you using a Feather M0 + a WINC 1500 breakout? Or are you using the Adafruit Feather M0 WiFi (integrated Winc1500 module)?

If you're using the M0 WiFi, you do not need to perform the WiFi.setPins call from your .ino code, it's added into this library already.

Thanks, uncommenting #define USE_WINC1500 and removing the WiFi.setPins call solved the problem!

Hi, I'm running into this issue but when I add #define USE_WINC1500 right after #include "AdafruitIO_WiFi.h" then I get the following error:

I'm trying to compile the following example from the library: https://github.com/adafruit/Adafruit_IO_Arduino/tree/master/examples/io_home_series/neopixel_and_thermometer

This is on a freshly installed Arduino IDE and latest dependencies

Any pointers on how to compile this?
