3.6.3 Operating the Example

When installation is complete, both COM ports are available. On a Windows PC, Device Manager runs (see Figure 33) (see Section 3.7 for how to open Device Manager).

device_manager_after_both_ports_slau533.pngFigure 33. Device Manager After Both Ports are Enumerated

The UART backchannel port name is "MSP Application UART1". The USB CDC interface for the simpleUsbBackchannel application is "F5529LP simpleUsbBackchannel". The CDC interface port only appears when the simpleUsbBackchannel application is running, whereas the backchannel port is present anytime the F5529 LaunchPad development kit is physically connected.

The COM port numbers associated with each are shown in the Device Manager. Open two instances of a terminal application, like Hyperterminal or Docklight, and associate one with the backchannel and the other with the CDC interface. Make sure that the terminal settings in each terminal application disable flow control and have baud rate set to 28.8 kbps.

When both ports are open, enter data into one of the terminal applications. The data should appear in the other terminal application. The same should work in reverse.
