PICDEM ? FS USB User’s Guide
1.4.4
RS-232 Interface
The PICDEM FS USB board fully supports RS-232 serial communications, including
hardware flow control (RTS/CTS signalling) generated by pins RA2 and RA3 of the
microcontroller. One RS-232 female connector and all supporting circuitry are included.
1.4.5
Status LEDs
There are four firmware-controllable LEDs, D1 through D4. An LED is turned on when
the corresponding port bit has the value of ‘ 1 ’, and off when the port bit is ‘ 0 ’.
The PICDEM FS USB demo board comes preprogrammed with firmware which uses
LEDs, D1 and D2, to indicate the current USB device state. Table 1-2 summarizes the
LED values in relation to different USB device states. The meaning of each of the USB
device states can be found in Chapter 9 of the USB Specification.
Note:
In bus-powered applications, flashing D1 and D2 in Suspended mode is not
recommended; the current draw is likely to exceed the limits specified in the
USB Specification. It is implemented in the original firmware for the
demonstration board for demonstration purposes only.

DEMO TOOL APPLICATION SOFTWARE
Included with the demonstration board is the USB Demo Tool software. This simple
graphic interface allows users to monitor and control simple board features, and
provides the ability to reprogram the PIC18F4550 controller via a bootloader
demonstration.
