This weeks deliverables:
This week, I worked on the Design Paper which is due this upcoming Friday. Specifically, I worked on improving my block diagrams and making a much more in-depth Gantt chart that we could add to the report.
I also worked on the RasPi and the seat pressure sensors this week. I was able to re-flash Debian onto the Pi and get it connected to the CMU Device network. After that, I installed and configured nginx so that the pi is now hosting a very basic website:
I was also able to assign it a static IP so that it can be accessed from other networks, so we can test while not on CMU wifi.
I also focused on the sensors, which arrived on Thursday. Since they arrived later than anticipated, I was able to conduct a preliminary test, just to ensure they were working as anticipated. This was done just using a multimeter and a basic voltage divider circuit. Now that I know that the sensors work, I can focus on wiring them up to the ADC. I was also able to find better documentation on the adafruit ADC I purchased, which help me write some preliminary code to connect the ADC to the rasPi.
Progress:
Due to the late arrival of the parts, I am slightly behind schedule on connecting up my sensors to the rasPi. I plan on working a bit extra on the project this week in order to catch up, and anything I am unable to do this week will also be worked on over Spring Break to ensure that I come back ahead of schedule or at least on time.
Deliverables:
This upcoming week, I am focused on connecting the ADCs, RasPi, and the sensors all together. I want to have the code written which can analyze the pressure of the person and at least return a digital value which can be used for further analysis.
