I have had a little experience with USB communication via C#.My question today is this.
Is there a way to find the % or otherwise level of a battery connected via USB? I am designing an application to check the charge in a battery that charges via a USB connection.
The initial idea came from seeing the Logitech K750 Solar Powered Wireless USB Keyboard that comes with a Solar app, enabling the total charge of the keyboard to be monitored whilst plugged in.
The battery I wish to monitor has no specific tech other than to limit the 5v USB supply down to 4.2v and cut off charging once the battery reaches full.
