Convert from character to hex

[JGSH]

Hi all,

How can I convert a character to a hexidecimal, then parse each.

For example, after it is converted to say... 1E, how can I put 1 into a variable and E into another?

Thank you

Not sure I completely understand what you need but is this what you mean

char c = 0x1E;

char hexBuffer[12];
sprintf(hexBuffer,"%x",(int)c);

now hexBuffer contains the string 1E. You can get each value out of there by looking at specific indices. To convert the value back you can use strtol with a base of 16

You could also extract the half-bytes (nybbles) by the following method

right_nybble = (mybyte & 0x0F);
left_nybble = (mybyte & 0xF0) >> 4;
