ACCOMPLISHED:
This week, we had our interim demos, and for these demos, I finished coding out a major portion of the UI process. It was being controlled by my laptop due to the fact that, in testing our firmware and hardware together, we also found some major issues with our first iteration of the PCB, so the buttons that we have on our current PCB don’t work. Additionally, I have completely finished implementing the PDR in C++, added a Kalman filter to it, and began testing and tweaking it to detect straps and distance accurately, some things that I am struggling with is the fact that because I am the one strictly testing the PDR the stridelength and step tracking is adjusted and tuned to my steps specifically so I need to do some research on what values would be best for distance ad step length for an average person so that it can work for everyone who is using the device.
PROGRESS / SCHEDULE:
In terms of progress, we are still slightly behind schedule; however, looking at our interim demo, I am not as worried as I was before about integrating our biggest issue, is getting our new iteration of PCBs here on time. For the next week, we will be integrating the PDR with the software and GPS so that routes are properly updated and tracked.
TESTING PLAN:
- For PDR, I am currently testing both indoors and outdoors with different distances. I’m testing 5m and 10 m walking straight to see if it can detect my step counts correctly and the distance correctly. Additionally, I am also testing distances with 90-degree turns to see if it is able to detect a turn and step. This will meet the USE case requirements as our main functionality is our device being able to navigate you correctly to the next device and if step length and distance predictions are wrong the navigation to the other device will also be wrong.
- For the UI, there isn’t really much testing to be done; it is just stepping through a false/real navigation and seeing if the screens are outputting the correct screens at each state.
DELIVERABLES / NEXT STEPS:
Next Week I will:
- Finish integrating the PDR with the GPS routing – next Saturday
- Finish implementing all stages of the GPS- need to implement the idle stage – next Saturday
- Figure out how to get the ESPs to detect each other and send the information between them, and depending on whether they are a receiver/sender, have the screens display differently – two weeks
