Testing the Real-Time Agent

Home

After configuring your project to use the Real-Time Agent, it's easy to verify that it's working properly.

1. Build your project, download it to your target hardware, start the debugger and click the Run button to execute your program.
2. Set a watch on a variable that is known to be changing. For this test, a good variable that changes continuously is the write index (wr_idx) for the Real-Time Agent output buffer.
   
    Click the Symbol Window button on the toolbar to open the Symbol Window then select RTA_Config — rta — out — wr_idx.
3. Click on the wr_idx icon, then drag and drop it into the Watch Window.
4. Enable Periodic Window Update from the View menu.
5. If the variable in the Watch Window is changing, then the Real-Time Agent has been successfully integrated into your application.

Note

• If you encounter any problems integrating the Real-Time Agent, working examples for the Keil MCB21XX boards can be found in C:\KEIL\ARM\RT Agent\MCB21xx.
• To use the RTA_printf() and RTA_scanf() macros, the I/O retargeting option must be enabled(see Configuring the Real-Time Agent).
