Hi,
I am using a Feather M0 with a datalogging firewing (RTC + SD card).

I have tried many sample sketches and many libraries, I have read various formums trying different solutions
but I was unable to write and read any data on the SD card.

I tried using the example sketches, first with
an arduino ONE
and later with an arduino DUE
and everything works perfectly.

At this point, I assume there is something wrong with the libraries.

any suggestions?

Thank you
Eric

Hi Eric,

I take it you had been using the Arduino libraries since you were able to switch over to UNO and DUE?

Were you able to successfully run the RTC test with the FeatherWing? That will help give us some idea if there is any communication.

Is there any other devices connected to your M0 beside this wing?

Note the warning here https://learn.adafruit.com/adafruit-feather-m0-radio-with-lora-radio-module/pinouts#rfm-slash-semtech-radio-module-2825156-12. You have to set the CS pin #8 High when using another SPI device.
