Thank you... I was just making a new thread about this topic... hopefully someone will give me a solution soon

Yesterday, I tried to use the digital IO in my opi zero3, with the Python GPIO package from https://opi-gpio.readthedocs.io/en/latest/ by Richard Hull It depends on having sysfs files in /sys/class/gpio/ My original opi zero has these files and it works, but my opi zero3 doesn’t have these files I learned that /sys/class/gpio is created if the linux kernel is configured with a specific option ON, as suggested in the documentation: https://github.com/rm-hull/OPi.GPIO https://linux-sunxi.org/GPIO Also, a developer has made a change on the opi.GPIO project to support opi zero3 https://github.com/rm-hull/OPi.GPIO/issues/79 I will have time to try this tomorrow... but I want to ask: is anyone using GPIO in its most basic way? As reference: I saw this older thread about zero3's GPIO... https://forum.armbian.com/topic/31493-how-to-enable-i2c3-on-orange-pi-zero-3/ It is using leebobby's "armbian" image, with raspi-config, and wiringpi Using my original opi-zero, I never needed to use armbian-config to enable basic gpio and the python opi.gpio just worked as documented Note: the opi.gpio only claims to support basic gpio, not i2c. Update: these are interesting potential solutions and discussions (but they are all from before there was armbian for opiz3) https://www.reddit.com/r/OrangePI/comments/16vfa4g/orange_pi_zero_3_gpio_python_library/ https://github.com/eutim/OPI.GPIO https://www.reddit.com/r/OrangePI/comments/16ioyri/gpio_python_library_for_orange_pi_zero_3/ https://www.reddit.com/r/OrangePI/comments/18iveo3/how_to_control_gpio_pins_in_android_orange_pi/

I tried the latest rolling release from Feb 4, and I have good wifi performance and 0.0 cpu load when idle I tried to use GPIO Python from https://opi-gpio.readthedocs.io/en/latest/ however, it depends on having files in /sys/class/gpio/… which my original opi zero has, but my opi zero3 doesn’t have. Does GPIO depend on a dtbo or a ko? Or is it an option in kernel config, or within armbian-config?

Thank you!!

Hello. Thank you for making this image. I recently refocused in my orange pi boards and want to try this 👍🏽 i hope I don’t get much trouble with basic GPIO usage

i thought someone had already made it work in the H3 In the H3, the problem is not the accelerated H264 decoding. The problem is MPV not able to display the frames with the GPU... I need time to get back in developer mode and play with Mesa configurations and rebuild.

Baryon, do you mean this is working in H3, outputting through HDMI or NTSC? with window manager? With X? What single board computer did you use? I want to try what you did... did you replace those libraries and run ldconfig? Then, what MPV command did you use? And, was it the Bookworm provided MPV?

Thank you to all the Armbian team for fixing wifi for the orange pi zero. I had to work with 5.x, but now I could upgrade to 6.x finally mc510: i used this to upgrade distribution https://wiki.debian.org/DebianUpgrade (there are 2 apt files) and the login welcome message shows all the versions right, even with the lsb_release -a

"w1" refers to the 1-wire protocol... it is just one application of GPIO, but it is not what you need for GPIO I wanted to use GPIO for the first time yesterday in orangepi zero, but was not successful... I will keep trying today.

If you have an amazon account you could get one or a pack of USB-TTL converters... it is what every body uses. It is almost a requirement, for playing with SBCs.

Since I don't like using chmod 777, I returned to using the USB-serial adapter, which does not require the chmod

Strangely, I entered "sudo chmod 777 /dev/ttyS1" and "python3 -m serial.tools.miniterm /dev/ttyS1 230400" worked This is something that other apps using serial need, like ROS

Hello, I have a lidar scanner, which I already made it work with a USB-TTL serial adapter... with a decoding python program... it works great However, I tried to use one of the serial ports in the pins of my orange Pi zero... UART1, in pins PG6,PG7... I have strange behavior When I test the serial port with picocom or screen, I see the flow of characters: picocom -b 230400 /dev/ttyS1 screen /dev/ttyS1 230400 However, my python program fails to read at the first character. With the python's own miniterm, I get the same error Anybody who is using ttyS1 successfully in Python? THANKS!! Post data: I enabled the ttyS1 with the addition of "uart1" after "usbhost3" inside armbianEnv.txt I also changed "console=serial" to "console=ttyS0" I get a few lines of characters, but then serial/serialposix.py exits with the exception

A USB battery bank will turn off the 5V for half a second, every time it is plugged or unplugged from the wall or car adapter. And the linux SBC will reset. There are some SBCs that have an onboard lithium charger, such as the Odroid U3

I have an i96... but now I only had time for my other SBCs. Great to see there was a recent update In this latest debian image, does it have good support of USB hubs?

Do a google search for "raspberry overlay filesystem" That way, when you turn from development to testing (under risk of power loss), the OS opens and operates files in an "undoable way". When the power shuts off, it just keeps the data since before it booted

TV out is working out of the box for Orange Pi zero, with the newest Debian image Thank you to those who worked to make it possible and to merge it

In a recent test, under linux 5.x, I got my orange pi zero xr819 to upload and download at several megabytes per second . But this time it was connected to my OpenWRT router (last time it was on a Verizon router).

The functionality of armbian_first_run.txt is not working at the moment... because "ifconfig" was removed, and there's only the "ip" command.

I learned about this when I was using odroids... maybe armbian and raspberrys works in the same way: https://github.com/Snoop05/raspberrypi/blob/master/expand-rootfs.sh https://forums.raspberrypi.com/viewtopic.php?t=338686 https://forums.raspberrypi.com/viewtopic.php?t=253531

Specializing in orange pi zero sorry for the bad audio… it is a new channel.

I tried the "armbian first run.txt" yesterday and didn't work

I tried using this in my orangepi zero, because my UART-USB connection is not working In the *.nmconnection file, do you need to have something specific in the uuid line? May I delete the line?
