On-Board Logic Analyzer
The DEMOQE board has a built-in 2-channel logic analyzer which may be
used to display captured data in real-time on a host PC. The logic analyzer
channels (IN0/IN1) are connected to the PTC0 and PTC1 signals on the
DEMOQE board by default via the J11 jumpers. The channels may be
connected to any of the processor pins by wire jumpers (not included).
The DEMOQE Logic Analyzer Utility, included in the DEMOQE Toolkit on the
accompanying DVD-ROM, displays the logic analyzer signals on a PC.
2.3
On-Board Virtual Serial Port
The DEMOQE board has a built-in virtual serial port which may be connected
to the QE processor’s SCI RXD/TXD. This allows certain PC applications to
be able to connect in a serial fashion to the microcontroller without the actual
use of serial port hardware.
The DEMOQE Terminal Window Utility, included in the DEMOQE Toolkit on
the accompanying DVD-ROM, is a generic serial port utility which works with
the DEMOQE virtual serial port or actual serial port hardware.
