Hi,

I've defined the __sys_write() and __sys_readc() functions as following:

int __sys_write (int iFileHandle, char *pcBuffer, int iLength)
{
unsigned int i;
for (i = 0;i (less than) iLength; i++)
{
putchar(pcBuffer); // print each character
}
return iLength;
}

int __sys_readc (void)
{
char c = getchar();
return (int)c;
}

Edited this part.

Thanks!!

For some reason the post was being clipped right after the angled brackets. I had to replace it with (less than) to show the intent.

Thanks

Any ideas what am I missing?

stdio.h :quest:

Okay, I'm an idiot. :~

I added stdio.h in a different file than I was compiling.

Fixed!
Thanks!! :bigsmile:
