I finally finished my painting robot project that used a xojo app on raspberry pi. I did use gpio but most of the control was via the serial port on the gpio which was attached to a can bus module.
I had it in the script but it got cut because I needed to streamline the video and tone down the technical talk. I mentioned it in the description though.
My next robot video will also use xojo because it’s just a super easy way to create a GUI on the RPi. Plus I already have the framework written.
Very cool indeed. I wrote a pen plotter driver at some point in a distant past, so I recognize the efforts required in the past. Impressive work with 3D printing too.
