I ran into some expected problem this week. Our Jetson Nano stopped working, and we ended up re-flashing it. The second problem is that the available library that is compatible with the LED strips are mostly integrated with RPi’s GPIO library, which makes integrating the LED library on Jetson Nano very hard. I ended up deciding to write our own LED library for Jetson Nano GPIO. This combined with the issue with our Jetson Nano itself, we need more time for the LED grid. This week’s progress is that we have a robust testing scheme for GPIO output, it will be easier to debug the LED algorithm later. If the LED strip does not work out, we will fall back to use individual LEDs to build the grid ourselves.
