EDIT: See comment below
Thanks alot, however I meant that given 3 values like 255,255,255 for black. How would I convert those values into hexidecimal (I presume) so that printcxy could take an rgb value as input.
Also another question is that, if I has several defined functions in a file let's say helperFunc.c how would I go about importing them into the main file as I want to seperate my code out 
thanks. I have tried creating a helperFunc.h file yet all it seems to produce is errors...

The Casio Prizm uses RGB 565, meaning 5 bits of red, 6 bits of green, and 5 bits of blue.
You are probably used to dealing with RGB 888, meaning 8 bits of red, green, and blue.
So, if you want to convert from RGB 888 to RGB 565, you would do the following:
Code:
rgb = ((r & 0b11111000) << 8) | ((g & 0b11111100) << 3) | (b >> 3);where r is 8 bits of red (0 to 255), g is 8 bits of green (0 to 255) and b is 8 bits of blue (0 to 255).
Converting backwards (from RGB 565 to RGB 888) is a bit more complicated, but you should be able to find tools/algorithms on the internet.

thanks. I have tried creating a helperFunc.h file yet all it seems to produce is errors...Here is a simple example:
helper.c
Code:
/* This means that we can define stuff in the header and include it here */
#include "helper.h"
/* This header is because we will use GetKey */
#include <fxcg/keyboard.h>
/* Contents of the function goes here */
void func(int a) {
GetKey(&a);
}helper.h
Code:
/* These are used so that if the header is imported multiple times, it doesn't redefine its contents */
#ifndef HELPER_H
#define HELPER_H
/* The same function signature we used earlier */
void func(int a);
#endif /* Ends #ifndef HELPER_H */main.c
Code:
/* Now we can use our helper function */
#include "helper.h"
int main(void) {
int key = 0;
/* Because we have included the helper.h header, we can use the functions defined in it. */
func(key);
return 0;
}Let me know if any further explanation is needed.
Note: whilst I didn't run this code, it at least compiled, and should work theoretically.
Thanks it all works, however I have been recently trying to get a shape to work, I have used ShapeBase per one of the earlier posts as seen in the link
It all works however is there a parameter to make the shape, like circle to be filled.

I know this is abit late, but I would just like to thank everyone for the taking the time to respond to my questions.
