Has anyone used a UnitV2 to stream the camera video? It appears that the ffmpeg in /usr/bin has been compiled with most of the video options disabled (e.g. libopencv, libx264, libx265,etc.).

I noticed that there is very little free memory available on the device ~65MB. If I use Jupyter Notebooks, each notebook uses ~20MB. I get memory errors even when using only a single notebook.

Has anyone done much other than the OOB examples?

I am getting memory errors when trying to view video in Jupyter notebooks.

Is there a reason that there is no Swap space set up? The SD card that came with the unit is empty.

With so little physical memory it seems that a Swap space is required.

I watched the UnitV2 Webinar on Hackster and would like to get a copy of the UnitV2-mqtt-demo.ipynb Jupyter notebook that was used. Is that available?

I am trying to use the camera at full resolution (1080p). The default resolution appears to be 640x480@15fps. I've tried using OpenCV in Jupyter Notebooks but I can't set the resolution higher than 640x480. I was able to set 320x240@30fps, but also could not set a lower resolution (160x120).

Is there a document that describes how to configure the camera?

Thanks Felix,

That helped. I guess from the documentation I thought that just adding the M5StickCPlus library would work. I have verified that some other programs do work (Display, TFT_Clock, PowerWake) with adjustments for the larger display size.

The AXP192 and I2C_Tester programs work with your changes although I left Wire.begin() at default because I was checking the bus on the Grove port and that now is working.

I did notice that on the Plus there is a small current draw on the battery (-0.5 mA) when I am running on USB power but it is 0mA on the StickC.

I'm having a real basic issue programming the M5StickCPlus. I am using the M5StickCPlus library but the only program that works correctly so far is the FactoryTest.ino.

I tried using AXP192.ino and I got the following error:
M5StickCPlus_AXP192:38:16: error: 'class AXP192' has no member named 'SetLDO3'
M5.Axp.SetLDO3(false);

I did #include <M5StickCPlus.h>

I also tried I2C_Tester.ino and it runs if I don't have any external I2C devices, but if I add an I2C device in the Grove port - the Display no longer works.

Is there something else that I need to do besides changing the library reference to use M5StickC programs with the Plus?

If you are using a Grove ToF from Seeed there are pads to add a two pin header for the Xshutdown input and Interrupt output pins. You can use another GPIO to disable the first ToF while you program the second one to a different address. You do have to reprogram it every time you power up. Probably just easier to get the PaHUB.

I just got an M5Stack Fire and when I upload example programs they do not run unless I unplug the USB cable. Is that normal?

The last message in the upload window is:
Leaving...
Hard resetting via RTS pin...

Is it possible that isn't working? Pressing the power button doesn't fix it either, only unplugging the USB cable.
