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 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?

Hi Felix,

I discovered that the problem with the stream not starting is related to poor WiFi performance. It works when I put the M5CoreS3 near my WiFi access point.

From the comments in your program source, I guess you don't expect most of the features other than streaming to work.

I had hoped that resize and face detect might work. V-Flip, H-Mirror and Save seem to work.

Thanks, it's a place to start.

Hi @felmue,

Both of those partition files allowed me to compile and upload, but both have a different runtime partition error. I can connect to the webserver, but there isn't any stream. Not sure if that is caused by the partition errors.

With the original partitions,csv:
12:02:12.823 -> E (591) esp_core_dump_flash: No core dump partition found!
12:02:14.972 -> hello
12:02:15.235 -> Camera init ok.
12:02:15.268 -> Camera sensor found.
12:02:15.268 -> Camera PID: 0x9b GC0308_PID: 0x9b.
12:02:15.302 -> cam_hal: EV-VSYNC-OVF
12:02:15.807 -> .....................................
12:02:33.807 -> WiFi connected
12:02:33.847 -> Camera Ready! Use 'http://10.0.0.139' to connect

With the 8MB APP partitions.csv:
11:35:14.013 -> hello
11:35:14.013 -> Camera init ok.
11:35:14.013 -> Camera sensor found.
11:35:14.013 -> Camera PID: 0x9b GC0308_PID: 0x9b.
11:35:14.013 -> cam_hal: EV-VSYNC-OVF
11:35:14.013 -> ......................................................
11:35:36.199 -> WiFi connected
11:35:36.199 -> E (30217) MFN: Partition Not found
11:35:36.199 -> E (30217) MFN: Please Set the Partition
11:35:36.199 -> Camera Ready! Use 'http://10.0.0.139' to connect

But in either case there is no stream or image.

If it is working for you, I must just have some issue with my setup. I'll admit that never tried to set up partitions before. I don't even see the M5CoreS3 n the boards.txt file.

Hi Felix,

Thanks - I just tried it and it ran out of storage space after compiling.

"Sketch uses 3259241 bytes (103%) of program storage space. Maximum is 3145728 bytes.
Global variables use 74760 bytes (22%) of dynamic memory, leaving 252920 bytes for local variables. Maximum is 327680 bytes."

I've been using the Partition Scheme: "16M Flash (3MB APP/9.9MB FATFS)"

Are you using a Custom Scheme?

Has anyone gotten the GC308 camera on the M5CoreS3 working with the ESP32 CameraWebServer example? If so, what configuration did you use? I'm compiling with the Arduino IDE 2.3.2 and tried using the pinout from the M5CoreS3 library Basic->Camera example that didn't work.

I am using the Arduino IDE with the M5CoreS3 library and am having a reboot issue due to a PSRAM error when I upload any of the Basic examples. I have configured the boot setup per the documentation.

Arduino IDE 2.3.2
M5CoreS3 1.0.0
M5Unified 0.1.16

Can someone help me debug this?

Thanks.

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.
