Naturally, a lot of my time this week was spent working on the design report. Most of my focus was on the system implementation section, as well as some time spent on design requirements, architecture, and tradeoffs.
In terms of additional progress on getting physical things working for our project, I was fairly limited this week due to waiting on the Raspberry Pi Picos to arrive for most of the week. I was able to due a lot of research on how to implement our signal generation on the Pico and its GPIO capabilities. There appears to be options for hardware timed PWM and software timed overall pulses (calls to sleep on the Pico are much more accurate making this a viable option) as well as hardware timing for our entire signal generation. This puts me in a good place for next week to get our signal generation working on the Pico.
I am still nicely on schedule for the project. As mentioned last week we had to shuffle some things around on the schedule, but I am on track with our new order of implementation.
Next week I will definitely be able to get the signal generation on the Pico working to the point where we can view sent words on the oscilloscope. Hopefully I’ll have time to work a bit ahead as well and help out with the signal detection and decoding side of the program as well.
