Checking Serial Output

To check the serial output from the BLINKY program, connect a 3 meter, Male/Female DB9 serial cable from the COM1 serial port on the board to an unused COM port on your development PC.  Use a terminal emulation program, such as Microsoft Windows HyperTerminal, to display the serial data on your PC monitor.

Note

  • The MCB2140 Evaluation Board is a superset of the MCB2130 Evaluation Board. All MCB2130 examples (BLINKY, SOUND, and VOICE) work with the MCB2140.

To start the Microsoft Windows HyperTerminal application, select Start — Programs — Accessories — Communication — HyperTerminal.

  1. Enter a Name for the new connection, for example: MCB2130.
