Convert IR Code to Unsigned Long

hi, hope can help.

i quite new this, gentle! have searched forum can't quite find need.

i using nrf24l01 modules communicate between raspberry pi , arduino uno. that's working fine. have pi sending ir code (0xe0e0f00f - samsung mute in instance), it's broken each individual ascii code , broadcast arduino, receives each code , puts string together. can receive , print can't it!

i using rf24 send ir command. if use ir code directly (without me transmitting in) ie: irsend.sendsamsung(0xe0e0f00f, 32); works fine. but, if use string: irsend.sendsamsung(cmd ,32); get: "error: no matching function call 'irsend::sendsamsung(string&, int)'" - seems expecting 'long unsigned int'.

i have tried can find convert command in long unsigned int , many varieties thereof! please me work out or point me in direction? appreciated.

here full code - it's been cobbled examples , millions of searches!!

code: [select]


#include <spi.h>
#include "rf24.h"
#include <irremote.h>
#include <irremoteint.h>

irsend irsend;
bool radionumber = 0;
rf24 radio(7,8);

byte addresses[][6] = {"1node","2node"};
unsigned long got_code;
string cmd;
char letter;

void setup() {
   //led blink
   pinmode(9, output);
 
   //set radio
   serial.begin(57600);
   radio.begin();
   radio.setpalevel(rf24_pa_low);
 
  if(radionumber){
    radio.openwritingpipe(addresses[1]);
    radio.openreadingpipe(1,addresses[0]);
  }else{
    radio.openwritingpipe(addresses[0]);
    radio.openreadingpipe(1,addresses[1]);
  }
 
  // start radio listening data
  radio.startlistening();
}

void loop() {
 
        //get radio
        if( radio.available()){
                                                                    // variable received timestamp
        while (radio.available()) {                                   // while there data ready
        radio.read( &got_code, sizeof(unsigned long) );
        }
     
        radio.stoplistening();
        letter = got_code;

        radio.write( &got_code, sizeof(unsigned long) );              // send final 1 back.     
        radio.startlistening();
       
        //if it's got hash @ end it's end of code
        if (got_code != 35){
        cmd = cmd + letter;
        }
        else
        {
        //blink led
        digitalwrite(9, high);
        delay(100);
        digitalwrite(9, low);


        //send command
        irsend.sendsamsung(cmd,32);
        serial.println(n);\00
        cmd = "";
        }
 
      //serial.print(f("sent response "));
      //serial.println(ltr);
   }

} // loop

i have tried can find convert command in long unsigned int

the string class has toint() method stupidly named, since not return int. should @ code see return.
