4/13/2023 0 Comments Raspberry zero camera setupThe main differences are the tweaks for 1080p video, and the addition of a few lines to create a serial device endpoint (acm.usb0). For that, we run the following command to cause systemd to run a getty (all one command, not separate lines) sudo ln -s of the scripts that’s called as part of the piwebcam service startup us multi-gadget, which was published on the Raspberry Pi forums in a post by g.letourneur, and I added the extra serial gadget functionality from a few other posts. Next to set up the new serial device /dev/ttyGS0 to present a login prompt at boot. Now to build the uvc-gadget app, just run ‘make’ in the uvc-gadget directory: cd /home/pi/uvc-gadgetĪll going well, you should now have the uvc-gadget binary ready to be executed at the next boot. modules-load=dwc2,libcompositeĪlso edit the boot config, adding an extra line at the end containing: dtoverlay=dwc2 This enables the on-the-go mode of the USB interface, and allows us to create a multi-fuction gadget on top. Next, edit the kernel command line parameters at /boot/cmdline.txt, adding the following at the end of the “console” line. To install this, just copy the file into the correct location, and enable it: cd /home/pi/uvc-gadget It just runs the piwebcam script, which creates the multifunction device and runs the uvc-gadget application. I’ve supplied a file for this, which looks as follows. That will create a uvc-gadget directory, so lets configure the system now. It’s a forked version of uvc-gadget, with additional systemd and configuration scripts. Later on on the article we’ll power down the pi and plug it into a USB port on a Windows PC.Īll the scripts needed for this are in a repo on GitHub. □ This is usually done while the Pi is connected to a monitor so you can run raspi-config to enable the camera, ssh, configure WiFi, etc. There’s plenty of howto’s out there on how to do that. So the first thing to do is install RaspiOS on an SD Card, and enable the camera.
