Linker errors and Arduiono setup for ENV Hat
-
I am having problems linking the example for the M5Sitckc environmental module from github.. I am new to Arduino-- and have created a sketch call MstickC_ENVHat and copied all the code modules into the sketch in "tabs" so I have the main sketch MstickC_ENVHat, and the following in tabs DHT12.CPP, DHT12.h, bmm150.cpp, bmm150.h, bmm150_defs.h
https://github.com/m5stack/M5StickC/tree/master/examples/Hat/ENV
I guess I just need to understand how to make this example work as I am not familiar how to get this work?
I am getting linker errors...
Linking everything together...
