How can I convert a byte array to float?
Code:
void send_data() {
CCPACKET data;
data.length=2;
float lon=26.533255;
float lat=27.533463;
data.data[0]=lon;
data.data[1]=lat;
if(cc1101.sendData(data)){
Serial.println(data.data[0]);
Serial.println(data.data[1]);
Serial.println(" sent ok ");
return true;
}else{
Serial.println("sent failed ");
return false;
}
}
The problem is when I print those two variables it just prints lon 26.00 and lat 27.00 but not lon 26.533255 lat 27.533463 as I expected.
Here is the header file for CCPACKET I use:
#ifndef _CCPACKET_H
#define _CCPACKET_H
#include "Arduino.h"
/**
* Buffer and data lengths
*/
#define CC1101_BUFFER_LEN 64
#define CC1101_DATA_LEN CC1101_BUFFER_LEN - 3
/**
* Class: CCPACKET
*
* Description:
* CC1101 data packet class
*/
class CCPACKET
{
public:
/**
* Data length
*/
byte length;
/**
* Data buffer
*/
byte data[CC1101_DATA_LEN];
/**
* CRC OK flag
*/
boolean crc_ok;
/**
* Received Strength Signal Indication
*/
byte rssi;
/**
* Link Quality Index
*/
byte lqi;
};
#endif
I was trying to fix it by this part of code, but without success:
float lon=26.533543;
*((float *)data.data[0]) = lon;
Can someone help me to convert the byte array to float?
float
uses?
