If you check the code you see that it just keeps the chips defaults (many libraries do). So from the datasheet then: The default full scale value range is 2g and the high-pass filter is disabled.The default value is 000 for a data rate of 800 Hz. (From me: That is of course only when you actually also sample it that vast via your connection). It uses also standard 14-bit accuracy.
I am not certain what are you asking, can you specify more? Have you seen the FRDM KL25Z with the accelerometer. It uses default i2c frequency, which is set to 100k.

if you check the MMA8451Q datasheet, you see that the device can be configured regarding quite a few parameters. Among others:
The documentation of the library is not telling which is the "full_scale" "output data rates" etc. that is being used. This is just what I want to know.
Thanks for your help, Manuel
