From what I’ve been able to find, I should be able to communicate over USB with a raspberry pi. I programmed the camera on my laptop, and saved the data under tools-\>save open script to OpenMV cam. I tried downloading the IDE for the pi onto the pi, and it was missing some libraries, which I also found some forum post on. saying how to fix it.

When reading in information using serial on the Pi, I got the message "Micropython v1.9-4580-g7747c5b36 on 2019-09-27; OPENMV4 with STM32H743\r\nType “help()” for more information.\r\n\>\>\> "

My questions are:

1. Do I need the IDE on the Pi to run code on the camera when it is previously plugged into the Pi?
2. If no from what I read, all of the print data should be sent across the USB cable, is this correct, and can I read it in with serial.Serial()?
3. If I’m just confused and don’t know what I’m talking about, what is my next step?
