This week I worked on the system-level implementation of our project as well as improving the accuracy of the GPS unit. I played around with some configurations in the chip and changed to a configuration better suited for a person walking as opposed to a driving configuration which is default. With this different configuration, I gathered some extra route data that Zach and I can use to simulate a walk which should allow us to quickly debug and test our routing/feedback code.
I spent the majority of my time this week working on interfacing with the cellular data card, using the text-to-speech engine and outputting the audio form the pi to the user. By the end of next week I hope to be done with most of the system admin/device development so that Zach and I can collaborate more on incorporating the routing and feedback functionality into the device.
I finished most of what I hoped to do this week and I am happy with where I am on the schedule. At this point going forward I will be spending the majority of my time helping with the routing functionality and incorporating that into the pi.
