- We got our RPi 4s!
- Returned the mini HDMI cables because the HDMI ports on the RPi 4 are actually micro HDMI
- Since we don’t have micro HDMI cables to display the RPi’s desktop, we are working on trying to ssh into the Pis. For that, we need to get the RPi connected to the internet (either via the ethernet cable or wifi)
- We found a site containing instructions on how to connect the RPi to CMU-DEVICE wifi and are going to follow that.
- Explored different motor control/GPIO libraries for Raspbian
- The Python library is easy to use but may cause jitter because Python is inherently slower and may garbage collect at unpredictable times.
- The C library is hopefully more reliable and may be better for our time-sensitive device.
- We’re still weighing the pros and cons of each
- Decided to use OpenCV to detect motions/gestures.
- Started working on design doc. Came up with key questions that need to be answered in our design review.
