Get the value from hex

*here is the question link : http://stackoverflow.com/questions/29308337/casting-char-to-byte

and now think about, how it works.

you get this number : 1427709952 and you should parse it like that.

< byte3

byte 2

byte 1

byte 0 >

Motor

indoor

outdoor

not in use

temp=1427709952; 

it is an integer value and the hex value of it is : 0x55192000. so if we parse it 0x55 : 85 , 0x19 : 25 , 0x20: 32. 

now we are doing it programmatically.

float motor=(float)((temp&0xff000000)»24); float indoor=(float)((temp&0x00ff0000)»16); float outdoor=(float)((temp&0x0000ff00)»8);

24,26 and 8 are the numbers of bits to shift. »8 means shift one byte, »24 means shift three byte, and you know an integer value is four byte. after shifting we do AND operation and get the values.
