AAC-Clydespace Avionics Software Challenge

You are given the LIS3MDLTR 3-Axis Magnetometer sensor. The data sheet is located at doc/lism3mdl.pdf

Task Description

You must use the C API defined in i2c.h to operate on an I2C bus.

We provide example stub implementations of this API in i2c.c. You are free to extend the provided stub functions for the API.

Please write a device driver that implements the following API:

• Get the full-scale configuration
• Get and set the output data rate
• Enable or disable the interrupt pin
• Read the output data of a specified axis

Development

You are provided this minimal repository, aac-code-challenge, please perform your work on branch <candidate_name>

Documentation can be found in aac-code-challenge/doc

Once complete, please repackage and email back this repo to your interviewers

Scope

You shouldn't need to spend more than a couple of hours on the task.

This is not a closed book assessment.

Extra Thoughts

If you have time, answer the following questions:

• What changes you would make to this interfaces for use in an RTOS environment?
• How might the I2C API be improved
