USB to UART Driver

The link to the USB to UART driver is broken on the firmware modification page (Firmware Modification - Guide | OpenEnergyMonitor). Also, are there instructions on how to specify the upload port? I get an error when attempting to upload via VSCode: “Error: Please specify upload_port for environment or use global --upload-port option.”

Please look at the “Learn” section and “Electricity Monitoring” → “Programmers”. You need to check which programmer you have - the drivers are different.

I’m afraid I no longer use any M$ software, so I can’t help with VSCode. I recommend you use the Arduino IDE, full instructions for installing and using that are also in ‘Learn’.

@Gwil: The errant link is:
