Sample Programs; Led Chaser; Io Interfacing; Buzzer - NEX ROBOTICS LPC2148 Pro Manual

4.0 SAMPLE PROGRAMS

The following sample programs are included in the CD. The sample programs are written in
keil uVision IDE version 4 by using the Real View complier
The hex file can be loaded on the microcontroller flash memory using Flash Magic utility.
Detailed instructions for loading a hex file using Flash magic utility are provided in section
2.3.2.
The default clock settings for all sample programs:

4.1 LED CHASER

Hardware Setup: Insert LED jumpers D1-D4.
Load the LED_CHASER.hex file from LPC2148>codes>LED CHASER folder using flash
magic on the microcontroller flash memory.
Description: After loading the hex file, press reset switch. This application code will blink
D1-D4 LEDs sequentially. The code explains how to use GPIO registers of LPC2148
microcontroller.

4.2 IO INTERFACING

Hardware Setup: Insert LED jumpers D1-D4.
Insert Switch jumpers SW1-SW4
Load the IO_INTERFACING.hex file from LPC2148>codes> IO INTERFACING folder
using flash magic on the microcontroller flash memory.
Description: After loading the hex file, press reset switch. This application demonstrates
simple IO interfacing on LPC2148 development board. The program basically explains how
to read a pin and control the output. To see the result, press any switch and observe the
corresponding LED glow.

4.3 BUZZER

Hardware Setup: Insert SW4 Jumper.
Insert Buzzer Jumper
Load the BUZZER.hex file from LPC2148>codes>BUZZER folder using flash magic on the
microcontroller flash memory.
