LED INTERFACING WITH LPC2148 PDF

This is the first example on LPC where we start with blinking the LEDs. In this tutorial, we are going to discuss how to configure the LPC ports as GPIO . Blinking LED Using ARM7 LPC Microcontroller: This is a beginner tutorial to make an understanding Easy RFID MFRC Interfacing With Arduino Nano. what is led,C program of led interfacing with ARM7 (LPC), protious simulation file, Description of GPIO Register, application.

The remaining 16 bits P0.

By this, the first 16 P0. Writing 1s produces lows at the corresponding port pins. It is recommended to configure the PORT direction and pin function before using it.

The remaining 16 bits Witb. As there can be up to 4 functions associated with a GPIO pin, two bits for each pin are available to select the function.
