1 This is the Readme file for the libs-device directory. This directory contains
2 code snippets which may be useful for USB device firmware.
5 WHAT IS INCLUDED IN THIS DIRECTORY?
6 ===================================
9 This module contains a function which calibrates the AVR's built-in RC
10 oscillator based on the USB frame clock. See osccal.h for a documentation
14 This header file contains a code snippet for usbconfig.h. With this code,
15 you can keep the AVR's internal RC oscillator in sync with the USB frame
16 clock. This is a continuous synchronization, not a single calibration at
17 USB reset as with osccal.c above. Please note that this code works only
18 if D- is wired to the interrupt, not D+.
