CCS V4 中变量观察的设置方法

Code Composer Studio V4 中变量观察的设置方法

在Code Composer Studio V4中,如果想在DSP运行的时候刷新变量值,需要设置一下DEBUG参数,默认情况下是CCS4是不允许刷新的

在DEBUG模式下,选择ToolsDEBUG

在Target中的Realtime options中选择第一项或者第二项

下面是help里的说明,与界面中的选项略有不同，但是可以参考

Realtime Options

• Halt the target before any debugger access:

• When the target is running and debugger requires access to the target (e.g.

user clicks on refresh button of a view while the target is running), the target will halt for a very brief moment to retrieve the requested data before it continues running again. During this time, time-critical interrupts will be ignored. This option is disabled by default.

• Enable silicon real-time mode (service critical interrupts when halted,

allow debugger accesses while running):

• This option is supported on only a selected number of emulators. When

enabled, debugger accesses will be allowed while the target is running. Time-critical interrupts are still serviced when the target is halted. This option is disabled by default.

• Enable polite real-time mode:

• This option will only be visible when silicon real-time mode is selected. When

enabled, CCS will prevent the target from being halted while the application is servicing a time-critical interrupt. If a debugger access requires the target to be halted when servicing a time-critical interrupt, the user will be asked whether Rude Real-Time mode should be enabled. In Rude Real-Time mode, the user regains control of the target while time-critical interrupts are ignored.

在变量观察窗口中最右角点击下拉按钮选择 Customize Continuous Refresh Interval…来设置刷新时间间隔，默认是5 秒。

在中间的图标中选择 Continuous Refresh 按钮来实现连续刷新
