How to use an I2C chip? (Adafruit MMA8451)

Ah, thank you, I am still not getting the accelleration (.. I think), but I just had a breakthrough, by setting stop:false, I just ran the following piece of code.

I2C1.writeTo({ address: 0x1D, stop: false }, 0x0D);I2C1.readFrom(0x1D, 1);

What this is supposed to do is return the device's ID, 0x1A, and I got 26 back, which indeed is 0x1A, I feel like I am really close to cracking this, thank you :D
