Feather AirLift with Feather M0 Proto - Errors / can't get w

[DrNebin]

Hello, I have hooked the Airlift Featherwing to my Feather M0 Proto. I installed and updated the WifiNINA Library and necessary libraries. When I try to upload the test code to the M0 I get the following error:

/Users/devinnamaky/Google Drive/Arduino/libraries/WiFiNINA/src/utility/spi_drv.cpp: In static member function 'static void SpiDrv::begin()':
/Users/devinnamaky/Google Drive/Arduino/libraries/WiFiNINA/src/utility/spi_drv.cpp:97:15: error: 'NINA_GPIO0' was not declared in this scope
97 | pinMode(NINA_GPIO0, OUTPUT);

581 | return (digitalRead(NINA_GPIO0) != LOW);
| ^~~~~~~~~~
exit status 1
Error compiling for board Adafruit Feather M0.

I have already used the Feather M0 with the Feather 128x32 OLED and both of those were working together. When I added the Airlift I added it in a stack underneath the OLED.

Any advice on how I can get the board working?

Did you use the Adafruit fork of the WifiNINI library? I.e. https://github.com/adafruit/WiFiNINA/archive/master.zip as detailed on https://learn.adafruit.com/adafruit-air ... ng/arduino.

Yes, I did that and I also used the example from the installed fork under Files -> Examples -> WifiNINA -> ScanNetworks:

Code: Select all

/*

 This example  prints the board's MAC address, and
 scans for available Wifi networks using the NINA module.
 Every ten seconds, it scans again. It doesn't actually
 connect to any network, so no encryption scheme is specified.

I went ahead and deleted all NINA libraries and re-installed them.

When I only install the Adafruit fork, I get a notification that my libraries have updates and it presents me with the option to update the Arduino WifiNINA library from 1.6.0 to 1.8.1. If I update the library, I get the results I posted about above.

On reinstalling it again I decline to update it and keep it at 1.6.0. In that case I do not get the above error messages. The code compiles and is uploaded to the board without errors. However, now in the serial monitor I only get

Code: Select all

WiFi Scanning test

And nothing else.

Advice?

[dastels]

Try removing the Arduino WifiNINA library. It might be conflicting. You shoudl only have the Adafruit fork.

Dave

[DrNebin]

I only have the fork installed.

[DrNebin]

Some additional information. When I uninstall all libraries, the library manager indicates the Arduino WifiNINA is not installed. When I then install ONLY the fork from Adafruit, the Library manager indicates Arduino WifiNINA is installed v 1.6.0 and needs updated (which I do not do).

Again, I only have one library installed, and it is the Adafruit fork. I believe there is a bug in the library which causes the library manager to see it as an old Arduino library.

The sketch hangs any time WiFi.XXXX functions are called. If I comment out WiFi.status then it hangs on WiFi.firmwareVersion. If I comment out both of those it hangs on WiFi.macAddress, etc.

I also notice that I am using the M0 proto and the sketch definitions don't directly reference it. I am wondering if I manually define the pins if it would make a difference (as opposed to letting the if statements do the job).

[DrNebin]

Okay I have resolved this issue. I wanted to post the solution here for others who may be in the same situation.

First, yes there is a bug in the Adafruit fork that forces it to show up in the library manager as an old Arduino WifiNINA. Ignore that and do not update it.

Second, The if statements within the provided test sketch do not properly assign the correct pins for the Adafruit M0 Proto I was using. You must assign them by hand. They are the ones in the first section:

Code: Select all

#define SPIWIFI       SPI  // The SPI port
#define SPIWIFI_SS    13   // Chip select pin
#define ESP32_RESETN  12   // Reset pin
#define SPIWIFI_ACK   11   // a.k.a BUSY or READY pin
#define ESP32_GPIO0   -1

Simply delete all the if statements and force these pin definitions. Then the M0 Proto and the Airlift Featherwing will work together normally.

Thanks for putting up with me.

[dastels]

Well done!

Would you like to convert your fix to one that works within the structure of the library and submit a pull request? It looks like the board model needs to be added to the first #if condition. I see the Feather M0 Express mentioned, but not the proto.

Hmm... Looking deeper.. into the Adafruit SAMD board support code I see (in ~/Arduino/hardware/Adafruit/samd/boards.txt on my installation).

Code: Select all

adafruit_feather_m0_express.build.extra_flags=-DARDUINO_SAMD_ZERO -DARDUINO_SAMD_FEATHER_M0 -DARM_MATH_CM0PLUS -DADAFRUIT_FEATHER_M0_EXPRESS -D__SAMD21G18A__ {build.usb_flags}

for the Feather M0 Express, but for the Feather M0 it's

Code: Select all

adafruit_feather_m0.build.extra_flags=-DARDUINO_SAMD_ZERO -DARM_MATH_CM0PLUS -D__SAMD21G18A__ {build.usb_flags}

Notably without the

Code: Select all

-DADAFRUIT_FEATHER_M0

that I expected.

You could add it (line 35 in my version which should be the latest) and make a PR for that. Once it's accepted and merged, the Adafruit WifiNiNi examples could be updated.

The repo is https://github.com/adafruit/ArduinoCore-samd.

If you like.

Further... I don't see an existing PR or issue relating to this. Which I find somewhat odd.

Thanks for all your work digging to find the problem

I'll be checking out a pull request on the WiFiNINA to add the #define for the M0 feather.
EDIT: https://github.com/adafruit/WiFiNINA/pull/9

First, yes there is a bug in the Adafruit fork that forces it to show up in the library manager as an old Arduino WifiNINA. Ignore that and do not update it.

Was this when you had both libraries installed, but only the Adafruit fork? I'm open to changing the library name within the adafruit fork to differentiate it from the original library.

[dastels]

Sweet!

This was with only the adafruit fork installed and no arduino library installed. I think differentiation is needed. Thanks.
