When installing ArduCamFocus (0.0.5) in OctoPrint; there is now a control visible for ArduCam Focus with a value of 100, and two arrows, a disabled one [<] and an enabled one [>] pushing the [>] button generates the following error message.

2021-02-24 04:35:34,864 - octoprint.plugins.ArduCamFocus - INFO - setting FOCUS to 110 2021-02-24 04:35:34,866 - octoprint.util.comm - ERROR - Error while processing hook ArduCamFocus for phase queuing and command ARDUCAMFOCUS: Traceback (most recent call last): File "/home/pi/oprint/local/lib/python2.7/site-packages/octoprint/util/comm.py", line 4605, in _process_atcommand_phase hook(self, phase, atcommand, parameters, tags=tags) File "/home/pi/oprint/local/lib/python2.7/site-packages/octoprint/util/__init__.py", line 1890, in wrapper return f(*args, **kwargs) File "/home/pi/oprint/local/lib/python2.7/site-packages/ArduCamFocus/__init__.py", line 98, in processAtCommand self.focus(self.current_focus + int(parameters)) File "/home/pi/oprint/local/lib/python2.7/site-packages/ArduCamFocus/__init__.py", line 85, in focus self.bus.write_byte_data(0xc, data1, data2) IOError: [Errno 121] Remote I/O error

What am I missing to figure this out?

First of all, Fantastic plugin! because of this plugin, I switched from picam v2 to Ardunio cam and it's so much better. My only gripe is that I don't leave my raspberry PI on and when I first turn it back on and switch to the control tab, the previous focus I had set isn't being applied. I have to hit either left or right one time before it applies the focus setting (even though the previous setting is still there). I'm using the latest Multicam plugin so I don't know if that's a problem.

I know AllaboutJay has a newer plugin for the arducam focus, but I don't like it as much as it has some problems. number 1 it has too much junk on the interface for just a focus camera that does not have ptz (even tho I hacked that plugin to remove everything but the focus slider on my rig). Also it does not save/report the current setting. everytime you pull up the webpage the focus slider is set all the way to the right...so it is hard to tweak.

rPi4 has arducam i2c interface on device 10 instead of device 0. I changed my code to point to dev10.
Here is the problem area:

__init__.py

	def on_after_startup(self):
		try: 
			self.bus = smbus.SMBus(10)  <------changed to 10.
		except:
			self._plugin_manager.send_plugin_message(self._identifier, dict(error="Unable to open SMBUS"))
		self.current_focus = self._settings.get_int(["FOCUS"])

However, I wanted to make the plugin autodetect the pi model but not sure how to do this. That data is available in octoprint but not sure how to reference it..something like this:

	def on_after_startup(self):
		try: 
                        if self.env.plugins.pi_support.model.find("Pi 4") > -1:
			    self.bus = smbus.SMBus(10)
                        else:
			    self.bus = smbus.SMBus(0)
		except:
			self._plugin_manager.send_plugin_message(self._identifier, dict(error="Unable to open SMBUS"))
		self.current_focus = self._settings.get_int(["FOCUS"])

but I am not sure how to get that data (from the system info) into the plugin. I suspect that it is supposed to use self._settings.get(), but the paths don't seem to be documented anywhere.

I am trying to add an arducam to my octopi setup and I'm having a confusing issue and don't know how to proceed.

I am entering the

if ! grep -Fxq "^#ArduCamFocus$" /boot/config.txt; then
sudo cat << end_of_file >> /boot/config.txt
#ArduCamFocus
dtparam=i2c_vc=on
dtparam=i2c_arm=on
end_of_file
fi

set of commands to set up the camera and all I'm getting back is:

-bash: /boot/config.txt: Permission denied

I know this will be some stupid, simple issue but I'm sshing into my pi as user "pi" with my password, but don't see why it's not working. If you can point me in a direction that can help me proceed with this, I would be very grateful. Thank you for creating this!

I followed directions, ssh in, the commands did not work so sudo nano /boot/config.txt and added the i2c commands. Went into raspi-config and enabled i2c then rebooted. I then rebooted the pi and all I get is the Arducam Focus with two small grayed out arrow boxes underneath it. Nothing like what is shown.

I upgraded to python 3, and I noticed that the plugin manager keeps installing the version that does not support python 3.
I've uninstalled it, and reinstalled via the plugin manager, but still getting the issue.

For some reason I can't set the focus while the camera is streaming. Not with your plugin and not with the sample scripts from ArduCam. If I stop the webcamd service I can control the focus.

Here's the error I'm seeing in the octoprint log:

2020-12-29 08:11:29,924 - octoprint.plugins.ArduCamFocus - INFO - setting FOCUS to 110
2020-12-29 08:11:29,925 - octoprint.util.comm - ERROR - Error while processing hook ArduCamFocus for phase queuing and command ARDUCAMFOCUS:

And here's the error I'm getting from Motorized_Focus_Camera_Preview.py:

mmal: main: Failed to create camera component

In order for the Software Update hook to function properly you must add releases in github that match the version number identified in the setup.py. So if you merge my PR, something like this for the next stable release.

Then if you create a new branch named rc in your repo and push testing changes to it, when you do the release like the below (important parts highlighted) anyone with Release Candidate enabled for the plugin in Software Update settings will get an update notice.

Hello,
I do apologize in advance, I am very much a newbie with it comes to raspberry pi's and Linux.

I purchased this camera with the hope that I could utilize it in Octoprint to focus on the actual bed and object being worked on.
Jneilliii, and others have been extremely helpful in pointing me in the right direction (https://community.octoprint.org/t/arducam-auto-focus-camera/21511/10), but I've run into this fault and I've not been able to find much about it.

I'm sure it's probably something very simple, but again, very very very new to this stuff.

Thank you.

Hello，

We leave a message here to express our heartfelt thanks for your help!

We have developed a plug-in for the Arducam PTZ camera.
Give you a brief introduction to the control menu:
This control supports the calibrated focus control of the camera. At the same time, it supports the rotation and pitch control of the pan/tilt lens. The user can complete the mechanical setting of the lens through the ZOOM control, and adjust the focal length through the Focus component. The ptz-til-pan control can control the pitch and rotation of the pan/tilt lens, the step is 0~180°, and the step speed can be adjusted to 5°/10°/20°. Switch the infrared filter by controlling the IRCut button control.

Most importantly, Arducam would like to give you a PTZ camera. If possible, send us your shipping address.

I have installed all prerequisites, but in logfile I still see the same errors:

No issue. I love you for making this tool. Thank you guys so much.
