Converting an int to a 2 byte hex value in C

Question

I need to convert an int to a 2 byte hex value to store in a char array, in C. How can I do this?

Answer 1

This function works like a charm.

void WORD2WBYTE(BYTE WBYTE[2], WORD Value) { 
    BYTE tmpByte[2]; 
    // Converts a value from word to word byte ----
    memcpy(tmpByte, (BYTE*) & Value, 2); 
    WBYTE[1] = tmpByte[0]; 
    WBYTE[0] = tmpByte[1]; 
} 

asumming the following:

typedef unsigned char   BYTE; 
typedef unsigned short  WORD;

Example of use:

we want to achieve this:

integer = 92
byte array in hex:
a[0] = 0x00;
a[1] = 0x5c;

unsigned char _byteHex[2];
WORD2WBYTE(_byteHex, 92);
