Qwiic Scale not working with micromod carrier board and NRF52840

Qwiic System
1

Hello, I have a Micromod Single Carrier board, a sparkfun nrf52840 processor and a Qwiic Scale-Nau7802. When I try and load an example supplied with the library for the NAU7802 it will not run. When I open the serial monitor it is as if there is not a program running. Is the Qwiic Scale compatible with the Micromod System and other items I am using.

Thanks!

Can you please verify you have the correct Board and COM ports selected in the IDE?

Also, be sure to complete the necessary steps to install the board definitions https://learn.sparkfun.com/tutorials/mi … ware-setup and whatnot before the example arduino libraries will work with the nrf52840 on the MicroMod/mBed platform

Finally, if neither of those work, try using the scale on another microcontroller (if you have one! Uno, esp32, etc) to verify the scale itself is functional

Thanks for the Reply. I have verified that the NAU7802 and load cell are working correctly with a UNO and it works perfectly running the code in the “EXAMPLE2_CompleteScale”. I have also successfully uploaded and ran the BLINK example used in the tutorial for the nRF52840 so I am confident that I have the right board and port selected. However, one thing that did confuse me a little is that in the tutorial there is a HEADS UP NOTE:

“Heads Up! The board package used for this guide has been depreciated by Arduino. SparkFun is aware of compile errors caused by this update and we are working on a fix. This section will be updated once that is completed. In the meantime, using v1.3.1 of the Arduino mbed-enabled Boards package still works.”

So, in the Tools menu, I have the ARDUINO NANO 33 BLE Selected and that is what is working with the Blink Example. The status LED on the nrf52840 is blinking the amount of time specified in the code.

Thanks for the help!
