Testing the Program

Testing the Program

The program can be tested using a terminal emulator software such as HyperTerminal, which is distributed free of charge with Windows operating systems. The steps to test the program follow (these steps assume serial port COM2 is used):

• Connect the RS232 output from the microcontroller to the serial input port of a PC (e.g., COM2)

• Start HyperTerminal terminal emulation software and give a name to the session

• Select File?New connection?Connect using and select COM2

• Select the baud rate as 9600, data bits as 8, no parity bits, and 1 stop bit

• Reset the microcontroller

An example output from the HyperTerminal screen is shown in Figure 6.57.
