DLP-RF430BP with TIVA C

Better ask TIVA related questions here:

Hello Guys !! 

I am using an TI  tag type 4, NFC RF430CL330H.

As a starting code I am using one that I looked for by this link "forum.43oh.com/.../

when I approach my Mobile to tag does not read anything. I do not know what I should do ? Or what I'm doing wrong ...

My goal is to be able to read data (random numbers) via nfc.

Any suggestions / help will be welcome.

regards. 

hello again !!

I like the first one.  but I do not see any demo code. The examples you sent me earlier are for other types of microcontrollers. I have seen codes coming in this link " www.ti.com/.../rf430cl330h-example-code " . But there is no demo for TM4C123.

A separate question ...  the rf430cl330h has a yellow capacitor in the upper right ? Is the copies I saw on the IT page do not have it, however in the 331H yes.

Hello Mohamed,

This document describes the examples offered in the firmware package Josh linked: www.ti.com/.../tiduby2a.pdf

For reference that firmware package is: www.ti.com/.../tidccp3

This is all we have in terms of code already existing on the TM4C. If that example is too complicated, then you need to do the work to port one of our simpler examples to TM4C on your own.

You are correct that the www.ti.com/.../rf430cl330h-example-code link doesn't have example code for TM4C, and we have no plans to add this. But this would be the right firmware to use to port to TM4C. I would recommend the G2553 project as that is also on a Flash based MCU so it should be easier to port.

I'll be very honest with you Mohamed, if you aren't comfortable with IDE's or porting the examples from www.ti.com/.../rf430cl330h-example-code to a TM4C123, the RF430 probably isn't a good fit for you.

Regarding the capacitor, that is something added to our v2.0 of the BoosterPack. It is there to help support field powered applications on the BoosterPack.

Ralph Jacobi, Already works for TIVA LP with energia example. What I need to know is, could I send analog input values?

the code I use is :

#include "NDEF.h"
#include "NDEF_TXT.h"
#include <RF430CL.h>
#include <Wire.h>


#define RF430CL330H_BOOSTERPACK_RESET_PIN  8
#define RF430CL330H_BOOSTERPACK_IRQ_PIN    12

RF430 nfc(RF430CL330H_BOOSTERPACK_RESET_PIN, RF430CL330H_BOOSTERPACK_IRQ_PIN);

double randomDouble(double min, double max, int numCasas){
  long _min = min * pow(10, numCasas) + 0.1; 
  long _max = max * pow(10, numCasas) + 0.1;
  return (double) random(_min, _max) / pow(10, numCasas) ; 
}       

        double Freq = randomDouble(10.71, 10.79, 2)+1839755.00;
        double voltage_1 = randomDouble(0.82, 0.88, 2);
        double temperature = randomDouble(18.30, 20.00, 2);
        double vol = randomDouble(3.10, 3.29, 2);
        
void setup() {
  Serial.begin(115200);
  delay(1000);
  Serial.println("Initializing I2C and RF430CL330H-");
  Wire.begin();                                                              // Initialize I2C subsystem
  nfc.begin();                                                              // Format RF430CL330H, prepare for data
  attachInterrupt(RF430CL330H_BOOSTERPACK_IRQ_PIN, wake_up, FALLING);      // Register interrupt to wake MCU when RF430CL330H INTO (IRQ) line triggers

  Serial.println("Creating NFC NDEF_TXT object-");
   
  String Value = "El valor actual de F_Tiva es de "; 
  Value = Value + (Freq/1000000) + " MHz. El V_Tiva detectado es de " + voltage_1;
  Value = Value + ", la temperatura_Nodo1 es" + temperature + ", el voltaje_Nodo1 es" + vol;
  Value = Value + ", la temperatura_Nodo2 es" + temperature + ", el voltaje_Nodo2 es" + vol + ". El informe de estado del equipo ha terminado. Hasta pronto.";
  
  Serial.println("Posting to RF430CL330H-");
  size_t ndef_size;

  ndef_size = Value.sendTo(nfc);                                       // Write NDEF data to NFC device memory
  nfc.setDataLength(ndef_size);                                            // Inform NFC device memory how much data is there

  Serial.println("Activating RF430CL330H RF link-");
  nfc.enable();  // Now we're live!
}

void loop() {
  if (nfc.loop()) {
    if (nfc.wasRead()) {
      Serial.println("Something has read the NFC device!");
    }
    if (nfc.available()) {
      Serial.println("Something has re-written the NFC device!");
      nfc.flush();
    }
    nfc.enable();  // If nfc.loop() returns true, it will have disabled the RF link as a side-effect.
  }

  Serial.println("<low power sleep>");
  Serial.flush();  // wait for unsent UART data to flush out before going into low-power sleep
  suspend();  // Enter indefinite sleep (LPM4 on MSP430, DEEPSLEEP on ARM)
  Serial.println("<wake up>");
}

void wake_up()
{
  wakeup();  // Signal Energia to wake the MCU upon IRQ exit
}

and I had these problems :

nfc_1.cpp: In function 'void setup()':
nfc_1.cpp:40:21: error: 'class String' has no member named 'sendTo'
Value = Value + (Freq/1000000) + " MHz. El V_Tiva detectado es de " + voltage_1;
