Checking Serial Output

To check the serial output from the BLINKY program, connect the COM serial cable 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: MCB950.
