Explan how you changed the camera resolution to 320x240@30fps?

@m5stack Thank you very much!

No, the Unit V's using a K210 processor not an RP2040

Change the partition scheme to "no ota"

@asmodev thank you feedback , we will check it.

I reboot with terminal and try LaneLine Tracker setting.
but I had same problem...

I try it:

Power on and start UnitV2 . Click gear icon and select "Switch to notebook mode". Open Jupyter main page. Click "New" and select "Terminal". type "reboot" and open camera stream page. Click little switch and there color change black to light blue. Select "LaneLine Tracker" on Browser GUI. Change L_max text box value 0 to 30 . Click “update” button. Line tracking process is stopped. but camera stream keep running.

Maybe, I think my unitV2 need initialize firmware.
Where is unitv2 initialize procedure?

@m5stack This is a very big issue, The M5Stack team needs to get this working, and the wifi access point!

The available memory is not a lot, so you have to control your program to apply for memory.

A new version of the firmware is comming soon ...

hi,
don't know why but if you set that line n°31 in comment, it seems to work

"# tvoc0.set_iaq_baseline(35187, 35502)
while True:

you may try to use the sample loop that you find in UIflow_Unit TVOC.

As you can see on the picture below, TOVC/eCO2 can be use in a classroom context and it works fine
I initialized it outside the window and came inside after

you input 5V level to the Device GPIO? .. the esp32 input voltage should lower than 3.6v. else it would be broken. I think your device was dead.

Thanks for your assistance

Hi,

I found a solution.
I have to limit the I2C frequency to 100,000kbps otherwise it won't work properly.
This is strange because a frequency of 400,000 kbps works for all other devices and the MFRC522 should work fine at that frequency.

If anyone has any idea on this limitation, I am very interested.

Thank you

@m5stack said in The range of values from an ANGLE between directly connected to PORT B and connected to PORT A via PbHUB is different:

ESP32 and mega328 has different ADC resolution

Thank you very much for your reply.

Yes, the ADC module on mega328 has a 10-bit resolution, whereas ESP32 has a 12-bit resolution. If this issue is just a resolution issue, the result should be 0 - 1023 instead of 15 - 745 or 0 - 715. If nobody can reproduce this issue, the PbHUB may be broken...

Thank you @flypeek,

Apologies for the delayed response as I was on leave. Thank you so much and looking forward to going through it shortly. :)

Cheers, Syd
