hi,frnds i would like to work with msp430g2553 and nfcboosterpack trf7970a in energia IDE .Does any one have energia library for TRF7970A boosterpack.

i have attached a pdf which helps to make a library for iso1443a and iso5693 (in this link ---->http://forum.43oh.com/topic/6304-trf7970abp-nfc-boosterpack-enegia-library/)

i tried this code for msp430g2553 but its not working please any one can help me

include

define enable P2_2

define CS P2_1

define interrupt P2_0

define CS_ENABLED digitalWrite(CS,LOW)

define CS_DISABLED digitalWrite(CS,HIGH)

void setup() { // put your setup code here, to run once: pinMode(CS,OUTPUT); pinMode(enable,OUTPUT); digitalWrite(enable,LOW); pinMode(interrupt,INPUT); SPI.setDataMode(SPI_MODE1); SPI.setClockDivider(SPI_CLOCK_DIV8); SPI.setBitOrder(MSBFIRST); SPI.begin(); Serial.begin(9600); }

void loop() { // put your main code here, to run repeatedly:

let(); } void let(void) { CS_ENABLED; Write(0x83); CS_DISABLED; CS_ENABLED; Write(0x09); Write(0x31); CS_DISABLED; CS_ENABLED; Read(0x49); CS_DISABLED; CS_ENABLED; Write(0x01); Write(0x88); CS_DISABLED; CS_ENABLED; Read(0x41); CS_DISABLED; CS_ENABLED; Write(0x00); Write(0x20); CS_DISABLED; CS_ENABLED; Read(0x40); CS_DISABLED; CS_ENABLED; Write(0x01); Write(0x88); CS_DISABLED; CS_ENABLED; Write(0x8F); Write(0x90); Write(0x3D); Write(0x00); Write(0x0F); Write(0x26); CS_DISABLED; delay(100); CS_ENABLED; Write(0x6C); Read(0xC0); Read(0x3E); CS_DISABLED; CS_ENABLED; Write(0x5C); Read(0x02); CS_DISABLED; CS_ENABLED; Write(0x7F); Read(0x04); Read(0x00); CS_DISABLED; CS_ENABLED; Write(0x8F); CS_DISABLED; CS_ENABLED; SPI.transfer(0x4F); Read(0x7F); CS_DISABLED; delay(20); CS_ENABLED; Write(0x8F); Write(0x90); Write(0x3D); Write(0x00); Write(0x20); Write(0x93); Write(0x20); CS_DISABLED; delay(5); CS_ENABLED; Write(0x6C); Read(0xC0); Read(0x3E); CS_DISABLED; CS_ENABLED; Write(0x5C); Read(0x05); CS_DISABLED; CS_ENABLED; Write(0x7F); Read(0xCD); Read(0x88); Read(0x77); Read(0x66); Read(0x00); delay(10); CS_DISABLED; CS_ENABLED; Write(0x6C); Read(0x00); Read(0x3E); CS_DISABLED; CS_ENABLED; Write(0x8F); CS_DISABLED; CS_ENABLED; Write(0x4F); Read(0x7F); CS_DISABLED; }

void Read(byte data ) { Serial.print(SPI.transfer(data)); }

void Write(byte data) { SPI.transfer( data); }

I don't know if anyone has done much with NFC and Energia yet. I own the TRF boosterpack and the RF430CL330H ones but haven't yet had the time to tinker. TRF's datasheet looked formidable at first glance a while back... but it is supposed to be a jack-of-all-trades chipset.
