This week I further flushed out the software. For the Pi code, I created an initial draft with C++ code that takes display data over UDP and outputs it to the LED matrices. I implemented some hall effect sensor logic so we can estimate the angular velocity and determine the timing of when to push GPIO data. I also interfaced with an external library (https://github.com/hzeller/rpi-rgb-led-matrix) to actually send the data to the LEDs. Beyond the Pi code, I also briefly tested the Jetson code to ensure that the logic for spawning a Docker container from C++ and correctly implementing shared memory worked.
I think the progress for the software is on schedule since most everything is done. All that’s left is integrating the software to make sure it works with the hardware. Next week my main goal is to laser cut the enclosure, since I am in another class that gives me access to a laser cutter.
