We’ve put a raspberry pi on our robot that communicates with our auton program using the microUSB port on the brain. The brain sends data (like odom position) to a program I’ve made on the pi, which then sends it to a program I’ve made on my laptop, moving around a little 3D model of our robot on a virtual field.
I figured similar communication could work using the microUSB port on the controller, but it seems the serial port is not exposed in the same way that the brain’s port is. It would be 10x easier to plug my laptop into the controller and get values from our program rather than attaching a pi + battery to our robot. There isn’t very much info online about it so I wanted to ask here. Does anyone know about this? Thank you.
