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.
For week 1, I was working on getting openCV working and being able to detect outline of objects.
So I started my work during the mandatory lab meeting and realized the numpy version on my computer was outdated since I hadn’t used it for a long time, and the python package installer was corrupted. So I had to spend about two hours figuring out what was wrong and reinstalling the packages. Besides that, I managed for my code to be able to detect feed from my camera, and perform background subtraction to detect an outline of the objects.
We have received all of our parts for our project. I started researching on how to create a Wireless Access Point using the Raspberry Pi. Each of the devices will be connecting to this WAP, so the hub can send it messages through it’s own …
This was our first status update for our project. While most of this week was waiting for parts to come in, we luckily had a spare RPi 4 that we could get started working on right away. First off, I needed to find a way …
We have just started receiving parts for our project and we have been working on the setup phase of our design as well as some more research on how we are going to implement our project.
