This week began with finishing up and practicing the design review presentation, which I gave during Wednesday\u2019s class. It went well, but Vyas did point out something that we haven\u2019t given much thought yet, which is how we plan to implement communication between the Jetson and the user\u2019s computer. This falls under Heather\u2019s domain, and she was quick to jump on the research for it.<\/span><\/p>\n

In addition, last week, I mentioned that we could no longer use the four-microphone I2S setup that we had planned to use from the start of the project, since the initial plan was to connect two microphones in stereo to each of the Jetson\u2019s I2S pins, which wouldn\u2019t allow us to separate the audio feeds in order to determine the difference in arrival times among the microphones and thus defeated the entire purpose of acoustic location. I also mentioned that we were down to two options: either using just two I2S microphones (one on each pin) or three I2C microphones using the remaining three I2C pins on the Jetson. I eliminated the former option this week when I realized that with just two microphones, based on the difference in the arrival time of the sound of the source at each microphone, there would always be two possible locations of the source. Thus, we had to go with the second option. Luckily, last week, in preparation for our two-microphone plan to go awry, I already placed the order for the three analog microphones and ADCs for I2C.<\/span><\/p>\n

While I wait for them to arrive, I will continue working with the two-microphone array just to get the foundation of the acoustic location algorithm working. This past week, after finally receiving my Jetson Nano, I was able to set it up. This coming week, I plan to get the two-microphone acoustic location algorithm working on the Jetson and to make notes of what will need to be altered when I switch to three microphones.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
