This is an I2C implementation for mma7660fc-based 3-Axis Digital Accelerometer. It is an embedded-hal driver as part of the weekly driver initiative by Jorge Aparicio.
The Device
The MMA7660FC is a ±1.5 g 3-Axis Accelerometer with Digital Output (I2C). It can be found on Seeed’s Grove 3-Axis Digital Accelerometer. It is made by NXP Semiconductor.
Development
For the development of this driver, I used the Grove 3-Axis Digital Accelerometer and tested on a Raspberry Pi 1 running latest version of Raspbian.
The Driver
It is quite straightforward to use the driver. The documentation provides a comprehensive explanation with an example. Essentially:
Add the mma7660fc crate as a dependency in the
Cargo.tomlfile. You also need an implementation forembedded-hal. For Raspberry Pi, I am using linux-embedded-hal.Initialise the Linux I2C driver and then create an
Mma7660fcinstanceRead the accelerometer values
Conclusion
This is a basic implementation of a driver for mma7660fc-based 3-Axis Digital Accelerometers. The driver does not implement all functionalities. Feedback, suggestions and PR are most welcome.
