17. MPU-9250 Coding Stuff

When we last left off, the MPU-9250 sensor was soldered, and so I had no more excuses to put off coding sigh.

The first tutorial I tried was this one, pictured above. The writer suggested this software called Visuino, and after following it, this is what I ended up with

I have to say this tutorial was really helpful and easy to follow, but the results weren't really what I could use. I basically just needed the readings to be numbers that were sent to the Serial port so I could read the information in Unity.

The next tutorial I tried was this, which still didn't give me the results I needed.

Finally, I found this YouTube tutorial which included this library, which after installation I managed to get the serial read to give me numbers I could use.

SOLID PROGRESS. I think next blog post I'll explain what I'm actually trying to do with all these sensors because I don't think I've explained it yet hahaha.

Update* Realised that the videos I added before were uploaded as images, reuploaded them onto YouTube to re-embed here, hence the later date of the video upload compared to the post.
