Got the new high resolution data for the height map.
I have been away this whole week for a conference in Atlanta, Georgia for my other major. I notified my team and professors in advance.
On the code side I have been trying to learn how Upstart works but Al told me that Raspberry Pi actually needs SystemD.
We got the first draft of the poster done as well. I also have started some research on the live line graph visualization.
I am looking into several ways of doing it.
I have setup time with my friends at the Linux User group to help me with any issues with SystemD I might have. It seems a lot of them know about it. I plan on getting the individual progress report this weekend as well as any new slides that I need to add to my part our presentation. With the Live Line graph I hope to get some work done on that over the break. It shouldn't take to long.
With having my friends about SystemD is that I can't get help until Spring term but I can learn as much as I can on my own though. Learn, Code, and Test. That's how you get better. With the live line graph the only issue is that we accidentally forgot about it because we were concerned about more pressing issues. Making one shouldn't be to difficult to be honest but I have to put coding off to spring break because of this coming week.
This week we worked out some issues with the communications with the ECE team. The data is going to be sent over USB, which isn't changing, but it turns out that the device that is sending the telemetry is using the Abstract Control Model protocol, which allows the host (the Raspberry Pi) to treat the device as a serial device. This actually makes our jobs much easier, because it eliminates the headache of worrying about identifying USB devices or figuring out which endpoint to connect to (USB devices can have multiple "endpoints", which allow for multiple streams of data to be sent/received over one connection).
I just barely got the migration to treating the external device as a serial device instead of a USB device finished, so the next step is to thoroughly test that new code. Additionally, we need some code to poll the serial device and check if something is connected. When that is done, I hope to lend a hand with the frontend to get the 3D visualization finished.
GitHub changed their markdown engine three days ago, and I just noticed it today while doing the blog post. We had to fix a lot of formatting to ensure that it meets the new, stricter, standards. It didn't take long, though, and was more of an annoyance.
