convert int to char dspic30f

[kenobe]

Hi
The mplab c30 compiler does not support itoa() function.
how do I change a hex number ie 0x55 to become a char '55' without using the printf().
Thanks

There is probably some easier way but this gets the job done,

	intVal=0x34;
	charout[0]=(intVal>>4)+0x30;
	charout[1]=intVal&0x0f+0x30;

Hi Pommie
Thanks for your help.
but what I need is charout[0] = 55 , not charout[0]=5, charout[1]=5

Isnt't that just

charout=(char)intVal;

or even,

charout=intVal&0xff;

I tried that too, but mplab c30 compiler does not work with casting and masking ,so it still does not solve the problem.

I found this hard to believe and so, I just tried the following,

#include <p30f2010.h>

unsigned int x;
unsigned char outchar;

int main(void){
	x = 0x45;
	outchar=(char)x;
	x = 0x45;
	outchar=x&0xff;
	x = 0x45;
	outchar=x;
	while(1);
}

It did exactly what I expected it to do.

Maybe you should post an example of what doesn't work.
