I started this week by doing some final preparation for the signal generation side of our system. I did some debugging on the Pico signal code as well as adding code to transmit letters from the Pi to the Pico over USB. We currently have the Pi sending letters from a queue in parallel to reduce the latency from the Vosk computation and output parsing. The Pi also sends one letter at a time, and waits for a response from the Pico before sending the next letter to avoid losing data if the Pico isn’t accepting more input.
In the middle of the week our project was ready to test the full system integration for one way communication. I worked with the rest of the group to get all of our subsystem integrated and perform some cursory tests to ensure the systems were integrated correctly.
Finally, I started the planning / making flow charts for implementing the two way communication.
We are still slightly ahead of schedule. We are in a very good place for our one way system to be presentable at the interim demo.
Next week I’ll finalize the plan for our two-way implementation and begin writing the code for that. I also want to spend some time experimenting with the Pico’s PIO for use with our signal detection which would allow us to parallelize the signal detection and would possibly simplify as well as improve the performance of the high end integration of the two way communication
