as we know the folder ..\leaflabs\cores\maple includes i2c.h/i2c.c
But why it has another wire.h/wire.c in the libraries? Just let us easy to use the I2C ?
What's the difference between them? what we should look out when we use the wire?

Thanks ……I'm fledgling...

i2c.h provides the low level i2c interface written in C that directly wraps the i2c hardware onboard Maple. wire.h provides the c++ class and gives something a simpler interface to i2c for Arduino Compatibility. If you are OK with a little of bit of C I recommend using i2c.h, if you prefer the arduino way of doing things or want to use software i2c (use pins other than the hardware i2c pins) then use wire.h

see the example here:
