Communication on the AVR side
Writing programs for the USB Communications port on the AVR side is supported by two different sections of
the Pololu AVR C/C++ Library.
The SVP-specific functions section of the library provides the rts_enabled() and dtr_enabled() functions which
return the states of those control lines. Complete documentation of the SVP-specific functions can be found
in Section 13 of the Pololu AVR Library Command Reference [http://www.pololu.com/docs/0J18]. A high level
overview can be found in Section 6.j of the Pololu AVR C/C++ Library User’s Guide [http://www.pololu.com/docs/
0J20].
The Serial Port Communication section of the library provides many functions for serial communication,
all of which will work for the USB Communications port. Complete documentation of serial communication
functions can be found in Section 10 of the Pololu AVR Library Command Reference [http://www.pololu.com/docs/
0J18]. A high level overview can be found in Section 6.h of the Pololu AVR C/C++ Library User’s
Guide [http://www.pololu.com/docs/0J20].
