Design

The sensors connect to the MoTeC ECU via wire, then the MoTeC connects to the RPi via Ethernet. The RPi logs the data and displays some of the results on the screen. When the testing session or race is over, the data can be sent to a device via bluetooth (probably a smartphone, which can then take the data where it needs to go). The Python script on the RPi uses the pygame package for the GUI, and connects to the MoTeC by sending and (mostly) receiving hex values. This milestone was focused on the connection between the MoTeC and the RPi., but the script also includes a basic UI that can be used for visually testing and the wireless transfer code can be ported from another, unrelated, project.
