@m5stack said in V-function Face Detect not working on Unit-V:

we just release a new firmware. you could remove the firmware then redownload it(same firmware version number) in the M5Burner firmware list. will be ok

Thanks. With the updated firmware, now I have the face detection v-function working now with the example in the docs.

Just got a Unit-V and was trying to use the face detection V-function. I burned the FaceDetect v1.1 firmware to the Unit-V using the M5Burner. I used the example in the docs (but on an M5StickC-Plus instead of a core) and I can't get it to detect anything.

Looking at the serial logs of the Unit-V, there is this error:

I think the firmware is not correct for the Unit-V. Any ideas?

Have a look at my GitHub project, where I implemented a simple menu system in the program. I use buttons to select different menu items and display different screens. It should give you an idea of what to do on the show/hide of the labels.

Or you can try this as well:

@jhonnytank

I apologize. I missed the fact that you were testing the hat. I only have the unit.

@jhonnytank

It's not good to have mismatched firmware when using uiFlow. I would recommend you flash your hardware to 1.6.3 so it matches uiFlow. Make sure you Erase before flashing.

I have no issues with the ToF unit using uiFlow v1.6.3 and firmware v1.6.3 on the m5stickC or m5stack core.

@felmue

I wouldn’t assume a change in the sticker also represents a change in hardware. For example, I have the initial release of the M5StickC (no copper nuts, which are actually copper mounting screw holes), red 5V IN on the sticker, and no “RTC” label on the sticker. However, my device actually has a functional RTC inside. So adding the RTC label on the sticker doesn’t mean they revisioned the hardware and added the RTC. It was always there.

I also cannot assume that the M5stack documentation is accurate 🤣. I think they make little revisions over time and don’t always communicate or document what was done.

@rop

Very nice enhancement! With multi-touch, someone could also implement pinch, spread, and swipe gestures for zooming, scrolling, etc., just like smart phones. Great work Rop.

@felmue

I'm using uiFlow firmware Beta2-core2 as listed in the M5-Burner app.
How can I read the registers to obtain the values?

@rop said in Capacitive buttons only work when holding Core2 or when sitting on metal surface:

Hmm, I see none of the effects described here. My touch screen seems to work fine, with cable plugged and unplugged.

You're lucky! The backlit area of touch screen is fine. It's the capacitive buttons (part of the touch screen glass, but below the actual IPS LCD screen) that have the issue for me. Please confirm if the capacitive buttons work for you in the scenarios described above (non-conductive surfaces).
