We worked on making our design presentation. Our hub can now communicate with another device if it’s connected through the Wireless Access Point through an echo server that uses a TCP connection. The SPI protocol is being worked on to communicate between the Wi-Fi board …
For this week I set up a echo server on the raspberry pi 4 hub. This server is using a predefined host address and port and clients need to be already connected to the raspberry pi’s wireless access point to communicate with the server. After …
This week that I learned that running OpenCV on a Raspberry Pi Zero can be pretty time-consuming. I had to compile and install opencv from scratch on the raspberry pi, instead of just being able to pip install, how I do it on my mac. The compiling itself was a 9 hour long process. While compiling the opencv library, at 95% I found that the version of openCV I had downloaded had a small error, so I had to search up stack overflow to figure out what the issue was.
This week was a lot of actually getting stuff working. All of our parts came in so I deep dived into the embedded side of things. The hardest part was trying to get a working toolchain to program the STM32. I had to make major …
We worked on setting up our devices. OpenCV was being installed on the Raspberry Pi Zero. A wireless access point was set up for the Raspberry Pi 4 for our main hub. UART was being set up to help debug the wearable and button devices.
