An example run of the DPP application is shown in

Figure 1. The three user LEDs should start blink-

ing. The LEDs represent Philosophers 0-2. An LED-on represents an “eating” philosopher. Extin-

guished LED represents philosopher “thinking” or “hungry”.

For the QS (Q-SPY) software tracing output, you need to connect a TTL to RS-232 transceiver to

the TAU board, as shown in

Figure 4. The figure shows the RS232 to TTL converter board 3.3V

to 5V from NKC Electronics (

http://www.nkcelectronics.com/rs232-to-ttl-converter-board-

33v232335.html), but you can use any other equivalent board.

To see the QS software trace output, you also need to download the Spy build configuration to the

target board. Next you need to launch the QSPY host utility to observe the output in the human-

readable format. You launch the QSPY utility on a Windows PC as follows: (1) Change the directory

to the QSPY host utility

<qp>\tools\qspy\win32\mingw\rel

and execute:

qspy –c COM2 –b 115200 –O2 –F2

This will start the

QSPY

host application to listen on COM2 serial port with baud rate 115200.

(Please use the actual virtual COM port number on your PC.) The screen shot in

Figure 5 shows the

QSPY output from the DPP run:
