Unable to compile SparkFun_Bio_Sensor_Hub_Library for Arduino Nano 33 BLE

sparky57 · May 6, 2021, 1:19am

Works fine when compiling for the Arduino Uno. The issue seems to be with Arduino Mbed Nano boards. I’m following the steps mentioned here

https://learn.sparkfun.com/tutorials/sp … okup-guide

I am using the example code and can’t seem to get it to compile.

Error compiling for board Arduino Nano 33 BLE.



This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Any suggestions on what could be causing the compile issue ?

Unfortunately the library isn’t compatible with the Nano 33.

sparky57 · May 7, 2021, 1:39am

Is the solution to just fix the error messages? I tried that and it works. Is there any reason the library isn’t compatible with the nano 33?

error: call of overloaded 'write(int32_t)' is ambiguous 
     _i2cPort->write(_writeVal[i] >> 8);

I don’t think it has been tested on a Nano33. The warning and error messages are because of different checks of the compiler. The warnings can be ignored. ( e.g. it is useless to check an ‘uint8_t’ on a value below zero or above 255, because it can never have that value)

The error is because the compiler wants to see an ‘int’. Thus a replacement of each of those errors with some like this should solve the issue:

int c = (_writeVal[i] >> 8) & 0xff;
_i2cPort->write(c);
