Using the RTA Control Panel Properties dialog box as shown in Figure 3-3,

you can control how frequently the host polls the target for log information. To

access the RTA Control Panel select DSP/BIOS

→RTA Control Panel. Right-

click on the RTA Control Panel and choose the Property Page to set the

refresh rate. If you set the refresh rate to 0, the host does not poll the target

for log information unless you right-click on a log window and choose Refresh

Window from the pop-up menu. You can also use the pop-up menu to pause

and resume polling for log information.

Figure 3-3. RTA Control Panel Properties Dialog Box.

Log messages shown in a message log window are numbered (in the left

column of the trace window) to indicate the order in which the events

occurred. These numbers are an increasing sequence starting at 0. If your log

never fills up, you can use a smaller log size. If a circular log is not long

enough or you do not poll the log often enough, you may miss some log

entries that are overwritten before they are polled. In this case, you see gaps

in the log message numbers. You may want to add an additional sequence

number to the log messages to make it clear whether log entries are being

missed.

The online help in the Configuration Tool describes LOG objects and their

parameters. See LOG Module in the TMS320 DSP/BIOS API Reference

Guide for your platform for information on the LOG module API calls.
