Description
Currently, the accelerometer has a simple bare-metal interface that returns raw data values. Next step is to convert this raw data into meaningful values.

Adafruit has implemented this in their .getEvent() method in the Adafruit_LSM303_U Library, where SENSORS_GRAVITY_STANDARD is defined in the common Adafruit_Sensor Library.

Look into the bare-minimum implementation required for getting the latitude and longitude in degrees. Upload any necessary code to document the effort.

The sample code used on the Arduino is a perfect example of this.

Allow the the DAQ to allow user input for starting data logging (initiate periodic outputs), and stopping data logging (safely closing the output file). Here are some ideas for commands:

Leverage OOP & Polymorphism. After having created an available API so that others can easily write to the SD card with a method, compile it all into its own SdDataLogger class. This class will inherit the abstract interface, IDataLogger class, for making the firmware more robust in accepting different data loggers in the future (e.g., the possibility of using USB).

Instead of the .txt file created in Mbed's example for logging to an SD card, create & write to an SD-Card. You may need to get in touch with our Software Lead for ensuring the order of the data in which it needs to be parsed, the current standard, & any modifications we should make.

Sub-tasks

• Meet with our stakeholder, the software lead
• CSV header and dummy values are written
• Select an error value for failing hardware

Note: In the long term, once we have a better understanding of our hardware, we may like to create a separate text file for logging error messages. For now, an error value in the corresponding field will suffice.

The previous implementation is already fairly re-usable — but we can do better. This time, make updates so that the implementation follows more closely with the style guide and is more user-friendly like other Mbed components.

I have implemented my previous work in a separate repo. Having moved from ST's HAL library to Mbed, figure out where to place the files to amongst our codebase, and make use of it for a basic implementation. This will be our fallback while guaranteeing this critical feature for the team. For convenience, determine whether the card insertion is consistent with the reset button.

Sub-tasks

• Move init() & deinit() autogenerated code to the Mbed environment
• Add the necessary files driver & BSP files for enabling FatFS

We have two analog air pressure sensors in our posession. Build an MVP for reading data off of them. Preferably, in kilopascal.

Note: From a quick online search, it seems that the datasheet's transfer function may a little noisy or somewhat high in error. Online users have made their own different modifications to it, so this may require several rounds of testing until we are satisfied with the results.
