Hi,

May I know which USB-Serial Adapter you are using? UC00A or UC00C? Which system you are running on your PC? Windows, Mac, Linux?

You got this error when you upload the sketch for first time?

Hi there,

I just bought Espresso Lite V2.0 with UC00A R3, after install all libraries using Arduino IDE v1.8.1, then connect the usb, I found the COM Port is not detected.

Can I know what is actually the problem?

Hi,

Com port not detected, normally comes from few situation.

1) UC00A R3 driver is not installed in PC
2) USB cable used to connect UC00A to PC

You can try check if the driver is ady being installed. When driver is installed successfully and connect USB cable to UC00A, you should be able to see COM port ( that time Espresso Lite not needed to attach yet)

Hi Sukuri,

Could you disconnect all, and just connect between your PC/laptop and UC00A? If still can't detect try with other PC/laptop.

Thanks for that.

I think the driver is the problem, can I know where can I get the driver to re-install?

I've tried connect with laptop only, but still COM port not detected. I don't think my usb port is the problem cause it works with arduino.

Hi, did you try with bengchet suggestion? Try to re-install the driver.

Could you printscreen your device manager?
