mma7660fc

A platform agnostic driver to interface with the MMA7660FC 3-Axis Accelerometer via I2C

This chip can be found on Seeed's Grove 3-Axis Digital Accelerometer(±1.5g)

This driver was built using embedded-hal traits.

Documentation

What works

• Read the XOUT register for value of x
• Read registers XOUT, YOUT and ZOUT to get 6-bits output value for x, y and z
• Set mode to active or standby
• Get acceleration within range ±1.5g

TODO

• Allow to modify sampling rate, currently initialised to 4 samples per second active
• Get other data such as orientation, tilt, etc
• Test with stm32f30x-hal, currently only testing with linux-embedded-hal
