OK, I have another problem. I have looked at this error message and cannot find out what is wrong.

Use unsigned int instead of int for hour, minute, second, and ms. Also, itoa doesn't return anything.
Still won't work.

This code shows the numbers 1-10, and then skips to 160. Why? Isn't there a way to get it to go from 0-60 and back to zero?
Heh, that's my fault; the BCD to decimal code that I told you has a glitch. I forgot a left-shift by 4:


Code:
      second = 10*((second&0xf0)>>4)+(second&0x0f);
I wrote this little program for fun, but it won't work. I only get the loading symbol. I have a feeling this is because it is not displaying the VRAM.

That's not a function call, it's just a nop.
OK, new question.

I know I saw how to do this somewhere but I can't find it back. How do I do a function that modifies a given variable?

The usage would be like this:

Code:

function (&var);



Thanks in advance Smile

You'd have a signature something like this:


Code:
void function(int * var)


Inside the function you'd change the value like this:


Code:
*var = 5;
Ok, what does the "*" do? Isn't that multiplication?

Pointers and indirection are a key concept of C programming, and it's vital that you understand them properly.
Hi!

I'm trying to set up the Prizm SDK on my Ubuntu 12.04 machine. I read this guide. GCC and binutils are already installed on my computer, so I wouldn't like to install them again. So how should I configure them to get them into work?
There's no way around it, you need a cross-compiler for SH3. Your currently-installed GCC and binutils are (unless there's something very unusual going on) incapable of cross-compiling for SH3, as they target your system only.
Thanks, I did it!
My thread's bee hijacked!

No, Just Joking that's ok, anyone who wants to can post here Smile

but, i have another problem.

It's supposed to draw a rainbow across the screen but all it succeeds in doing is freezing my calc. why?
flyingfisch wrote:

Code:
   for (ix=1; LCD_WIDTH_PX; 1) {

This loop can't terminate because it doesn't actually modify ix.

Code:
for (ix=1; LCD_WIDTH_PX; 1) {
This is not the syntax for for loops. This will loop infinitely. You want

Code:
for (ix=1; ix < LCD_WIDTH_PX; ix++) {


And also you probably want to start ix at 0.
ah, i get it.

Thanks Smile
