Checking Program Output

To check the serial output from the BLINKY program, connect a Male/Female DB9 serial cable (no longer than 10ft/3m) from the serial port connector UART #1 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.

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

  1. Enter a Name for the new connection, for example: MCB2400.
