03 -  USB code upload

Uploading is done with Visual Studio Code (VS) using the PlatformIO tab

During your 1st Upload, you must connect your TTGO or ESP32 to your PC with a USB cable

Thanks to VS you will load in the microcontroller the firmware and the HTML pages of the router

There are 2 uploads to do:

one for the firmware (the system code)

one for the filesystem (configuration files and website)

Then you can directly upload the code remotely with the /update page of the router
