NFC Controled RGB LED using LPC812

This project demonstrate the controlling of RGB led over NFC by smartphone. LPC812 MAX board is interfaced with NTAG I2C board (NT3H1101).

The pin connections are here,

P0_11 -> SCL_NTAG

P0_10 -> SDA_NTAG

P0_7 -> RED LED

P0_17 -> GREEN LED

P0_16 -> BLUE LED

The NTAG is having 476 pages with 4bytes per each page. For this project we used the page1 (4bytes)

byte1 - Led status (On/Off)

byte2 - Red value

byte3 - Green Value

byte4 - Blue

using of the android application , we can choose the color and corresponding RGB values will be write into NTAG memory page1 by tapping the smartphone in it. LPC812 is loaded with wo tasks , the 1st one to generate the PWM signal (bit banging) based on the time_buffers, the other one is to read the NTAG Page1 values and update the time_buffers.

Here with i have attached the source code , and soon the Android application is available in Google Play here.
