On-Board Logic Analyzer
The DEMOEM 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 PTA5 and PTA6 signals on the
DEMOEM board by default via the J41 jumpers. The channels may be
connected to any of the processor pins via wire jumpers (not included).
The Logic Analyzer Utility, included in the P&E Embedded Multilink Toolkit on
the accompanying DVD-ROM, displays the logic analyzer signals on a PC.
2.3
On-Board Virtual USB Port
The DEMOEM board has a built-in virtual serial port which may be connected
to the EM 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 Terminal Window Utility, included in the P&E Embedded Multilink Toolkit
on the accompanying DVD-ROM, is a generic serial port utility which works
with the DEMOEM virtual serial port or actual serial port hardware.
