I have gotten the libraries to build an am trying (unsuccessfully) to
make a custom putchar.c (I removed the putchar.s file). This is what I
have so far:
#include "memory.h"
void putchar(char ch) {
*(unsigned char *)pScreen = video;
*(unsigned char *)pX = caratx;
*(unsigned char *)pY = caraty;
char x;
char y;
x = pX;
y = pY;
pScreen += y * 160;
pScreen += x * 2;
if (ch = 0x0d) {
// Adjust the cursor position, checking to see if we need to
scrool the screen
return;
}
return;
}
It gets errors on just about every line. The first error says syntax
error: token 'char' where I declare x. Then, everywhere that a variable
is mentioned, it says undefined identifier - even when I declare a variable
the .h file is.
#ifndef MEMORY_H
#define MEMORY_H
#define caratx 0x1FFE
#define caraty 0x1FFF
#define video 0x2000
#endif
I simply use "sdcc putchar.c" without quotes to compile.
I have been trying for hours to get this thing to work. What am I doing
wrong?
