This week, most of my time was spent working on the design presentation and preparing to present, as I am presenting this presentation. Other than that, I finalized my design research into our IR communication protocol (pictured below) and worked out the encoding of letters and the timing of the protocol to ensure that we meet our use case requirements for speed and latency (200-250WPM and 500ms latency), while making sure that we’ll have enough leeway to handle errors. At the end of the week, I also worked on the code for our Hamming encoding, testing to make sure that it would fix single bit errors and detect 2 bit errors for our custom letter encoding.
I am well on schedule with my portion of the project, slightly ahead as I hadn’t planned on beginning coding until next week.
Next week I believe that a good chunk of my time will be spent working on. the design report. I’d like to also decide on a Raspberry Pi library to use for signal generation and detection through the GPIO. Changes with how the GPIO work from the Pi 4 to 5 have apparently rendered a lot of GPIO libraries incompatible with the Pi 5, so this will require some research to determine a good fit for our project. Hopefully I’ll be able to test some simple signal generation with Todd and the waveform generator at the end of next week.
