Hello,

I am aware that you can do face detection and QR reading with the Unit V or ESP32 Camera Module Development Board. However is there any example of combining the 2 into a single script / application for either the Unit V or ESP32 Camera Module Development Board.

Or is it better to keep them separate running off 2 units?

Thanks for any helpful comments and suggestions.

Hi

I have found Thonny a nice editor as well, it lets you interact with the shell and transfer files.

Is there a correct way to flash the firmware using esptool i'm using esptool.py --chip esp32 --port /dev/tty.SLAB_USBtoUART --baud 115200 write_flash -z 0x1000 M5StickV_Firmware_v5.1.1_beta.kfpkg becuase even though it seems to flash I cannot connect with Maixpy i'm getting the following Connect fail, board ide mode no ack

Any tips would be appreciated.

thanks Kyle

I'm looking for the Base Firmware for Unit-V, I was experimenting and have made a mistake with the unit-v and would like to know where I can get the base firmware so I can reflash to its default.

Thanks

Is there a newer / updated version of the firmware for Unit-V
I currently have this
MicroPython v0.4.0-52-g3b8c18b84-dirty

many thanks

Kyle

I got it work using python serial on the raspberry pi. It's now reading the input from the UnitV and performing functions based on that input.

I did need to disable the serial console on the Pi as it was causing issues.

I think the UnitV requires the 5v input as its not powering enough with the 3.3v using the GROVE connection.

I have the UnitV Sending output via UART GROVE to a M5StickC. Is it possible to attach to a raspberry pi GPIO and read the signal?

I have read that PIN 8 and 10 on the Raspberry Pi are UART TX and RX.
Has any one tried and confirmed this is possible. I will attempt this and report any findings.

Thanks

I had to use a windows machine with M5Burner because as much as I tried the Mac version would no work as expected. However I got it flashed back to UIFlow 1.4.5 and got it working now

Hello,

I am trying to flash the M5Atom and keep getting the following error. Is there a way to reset or get around this issue. It has occurred on both a Mac and PC.

Any advice will be very much appreciated.
