PICDEM ? FS USB
USER ’S GUIDE

HIGHLIGHTS
This chapter discusses the following:
? Common issues with the PICDEM FS USB demonstration board and how to solve
them
COMMON PROBLEMS
1. The Power LED is not lit.
Normally, the PICDEM FS USB board behaves by default as a bus-powered device. If
it is connected to a functioning USB port, the board will power-up and D7 will light. If
this does not happen:
? Verify that the USB port on the host system is actually working by plugging a USB
device that is known to be good into the port
? Verify that the cable is working by substituting a known functional cable
If a power supply is connected to the board, it will switch to Self-Power mode
automatically; D7 will not be lit and D8 will light instead. If this does not happen:
? Verify that the power supply is plugged in and the wall outlet has power. If battery
connection is used, verify that the correct polarity is used.
? Check that voltage is available (9 V DC ) at the power supply’s plug. If an OEM
power supply is not being used, check for appropriate voltage (9 V DC ).
? Check that the regulated voltage (5 V DC ) is available.
2. The appropriate Power LED is lit, but the system does not recognize the
board.
Check the USB cable for proper connections to the board and the computer. If
necessary, verify the cable by swapping in another cable that is known to be good.
If the Demo Tool software is running, press and release S1 to reset the board.
In Windows Device Manager (accessed through the System applet in the Control
Panel), use the “Scan for Hardware Changes” function to attempt to force the system
to detect the board.
It is possible that the only firmware programmed into the microcontroller is the bootload
firmware. In this case, enter Bootload mode by pressing and holding S2 while pressing
and releasing S1. If the Bootload mode does not work, it is possible that the firmware
has become corrupted. In this case, it will be necessary to reprogram the
microcontroller with the original firmware through an external in-circuit programmer.
