MCB517AC Evaluation Board User’s Guide 41
Typically, the first time you load the CPU driver for the 8051 monitor, you must
set the COM port and baudrate. If dScope cannot determine the com port and the
baud rate automatically, the following dialog box appears informing you that
dScope could not find the target system.
When using the MCB517AC evaluation board, the baudrate should be set
according to the DIP switch S3 and S4 settings (typically 9,600 baud). You must
determine which COM port of your PC you are using.
Next, you should configure the CPU driver to enable serial breaks. To do this,
select the Configuration command from the Peripherals menu. dScope displays
the Configuration dialog box shown below.
Finally, you are ready to load the BLINKY program. To do so, type the
following in the command window.
load blinky /* this loads the blinky program */
g,main /* this steps over the startup code */
/* and stops on the first line of main */
Once BLINKY is loaded, the module window displays the BLINKY program as
shown in the following figure.
