i am working on a project that requires me to read the filenames from a usb flash drive/pen drive. I could use a raspberry pi and be done with but the power requirements for a portable system is limiting. a friend recommend that i look into usb host and a microcontroller to go thru and read directory listing. i can't seem to find the best way of doing this.
- Power using a coin cell battery.
- 1 usb port
- 3.5in lcd display
- Read file and folder names.
What is the best way and/or are there tutorials?
Any help is greatly appreciated and pardon my grammar.
