Having Trouble Using SparkFun's Pulse Ox sensor with my arduino nano

ron_artest · November 2, 2023, 6:23pm

Im new to sparkfun’s sensors and im trying to connect a the pulse oximeter/ heart rate monitor to an arduino nano every. I have the hardware connections correct but every time I compile one of the example sketches for the pulse ox I get a message out like this and the serial monitor outputs jumbled letters.

Do you have another board to test with? It looks like there might be an issue with deprecated libraries… you may need to try uninstalling & wiping the arduino15 folder like so https://support.arduino.cc/hc/en-us/art … rduino-IDE - be sure to perform the “Removing additional files” steps, then try re-installing/starting over and see how it goes

Here are a few suggestions to resolve the issue:

Library Versions:

Ensure that you are using compatible versions of the SparkFun Bio Sensor Hub Library and Wire library. Sometimes, different libraries require specific versions to work together seamlessly. Check the library documentation or SparkFun’s website for any version compatibility information.

Library Order:

Try changing the order of library includes in your sketch. If SparkFun’s library includes Wire, you might not need to include Wire separately. Experiment with removing the #include <Wire.h> line from your sketch and see if it resolves the conflict.

Library Modifications:

If the issue persists, you might need to modify the SparkFun Bio Sensor Hub Library. Open the library’s SparkFun_Bio_Sensor_Hub_Library.h file and comment out or remove the #include <Wire.h> line if it exists. This prevents conflicts with the Wire library included by default.

Alternative Libraries:

Check if there are alternative libraries available for your pulse oximeter sensor. You might find other libraries that are more compatible with the Arduino Nano Every and do not conflict with the Wire library.

Arduino IDE and Board Package Updates:

Ensure that you are using the latest version of the Arduino IDE and that your board package is up to date. Sometimes, updating the IDE or board package can resolve compatibility issues.

Contact SparkFun Support:

If none of the above solutions work, consider reaching out to SparkFun’s customer support. They might have specific advice or updates related to your sensor and the Arduino Nano Every.

Remember to make backups before modifying [koo[ws libraries, and document any changes you make for future reference. If you provide more details about your setup and the specific error messages you receive, I can offer more targeted assistance.](CooMeet – Super Fast Best Video Cam Chat with Girls - Koows)](Omegle - Online - Koows)
