Still rebooted, but it displayed half of the pic this time! Yay for a little progress!
Yay! My new method works(I don't know why I didn't try it in the first place)!
Here's code:
Code:
int main() {
while(1) {
int key = PRGM_GetKey();
if(key == KEY_PRGM_MENU) { GetKey(&key); }
CopySprite(NyanCat1, 0, 0, 160, 160);
Bdisp_PutDisp_DD();
Bdisp_AllCr_VRAM();
CopySprite(NyanCat2, 0, 0, 160, 160);
Bdisp_PutDisp_DD();
Bdisp_AllCr_VRAM();
CopySprite(NyanCat3, 0, 0, 160, 160);
Bdisp_PutDisp_DD();
Bdisp_AllCr_VRAM();
CopySprite(NyanCat4, 0, 0, 160, 160);
Bdisp_PutDisp_DD();
Bdisp_AllCr_VRAM();
CopySprite(NyanCat5, 0, 0, 160, 160);
Bdisp_PutDisp_DD();
Bdisp_AllCr_VRAM();
CopySprite(NyanCat6, 0, 0, 160, 160);
Bdisp_PutDisp_DD();
Bdisp_AllCr_VRAM();
CopySprite(NyanCat7, 0, 0, 160, 160);
Bdisp_PutDisp_DD();
Bdisp_AllCr_VRAM();
CopySprite(NyanCat8, 0, 0, 160, 160);
Bdisp_PutDisp_DD();
Bdisp_AllCr_VRAM();
CopySprite(NyanCat9, 0, 0, 160, 160);
Bdisp_PutDisp_DD();
Bdisp_AllCr_VRAM();
CopySprite(NyanCat10, 0, 0, 160, 160);
Bdisp_PutDisp_DD();
Bdisp_AllCr_VRAM();
CopySprite(NyanCat11, 0, 0, 160, 160);
Bdisp_PutDisp_DD();
Bdisp_AllCr_VRAM();
CopySprite(NyanCat12, 0, 0, 160, 160);
Bdisp_PutDisp_DD();
Bdisp_AllCr_VRAM();
}
return 0;
}

I think that explains why it was exploding before- you have a bunch of independent images and were assuming they were placed in memory in the same order as the source code, which was probably not the case.
Given the binaries I could verify this (mmm, objdump), but whatever.

Hurray that it works! However, if I were you, I would put the pics in an array and make a loop. Maybe that's just a style preference, though.

Okay, so, quick question. I'm trying to make the green ball move after making the red ball stop, but the green ball doesn't move for some reason. I can't find what went wrong. Can someone figure this out?
Code:
int main() {
struct Coord cur;
cur.x = 0;
cur.y = 92;
int s = 16;
int a = 176;
int b = 0;
int c = 0;
while(1) {
int key = PRGM_GetKey();
if(key == KEY_PRGM_MENU) { GetKey(&key); }
CopySpriteMasked(Target, 142, 58, 100, 100, COLOR_RED);
CopySpriteMasked(RedBall, cur.x, cur.y, 32, 32, COLOR_RED);
CopySpriteMasked(GreenBall, a, b, 32, 32, COLOR_RED);
CopySpriteMasked(Arrow, 181, 146, 21, 70, COLOR_RED);
cur.x+=s;
b+=c;
if(cur.x >= 352 || cur.x <= 0)
s = -s;
if(b >= 184 || b <= 0)
c = -c;
if(key == KEY_PRGM_SHIFT && (s == 16 || s == -16)){
s = 0;
c = 16;}
if(key == KEY_PRGM_SHIFT && (c == 16 || c == -16))
c = 0;
Bdisp_PutDisp_DD();
Bdisp_AllCr_VRAM();
}
return 0;
}
Edit: I fixed up the code a little, but it still gives me the same problem. |

So a and b control the GreenBall, and cur (.x and .y) control the RedBall. Question: why did you not also use a Coord struct for the GreenBall...? That seems very inconsistent, and that sort of inconsistency is frowned on in programming. It looks like s is the x-velocity of the RedBall, and c is the y-velocity of the GreenBall (Pro Tip: long variable names in C don't cost you anything. Use descriptive variable names!). As makes sense, when you reach one of the edges of the screen, you reverse the direction of the RedBall, and the same with the GreenBall. When you press SHIFT and the RedBall is moving, the code should stop the RedBall and start the GreenBall moving. If you press SHIFT again, then the GreenBall stops too, and both are stopped. I see no particular problem; what happens when you press SHIFT? Does the RedBall stop, and the GreenBall fails to start? Or nothing happens?

When I press SHIFT, the red ball stops, but the green ball doesn't start.
It starts fine without this:
Code:
if(key == KEY_PRGM_SHIFT && (c == 16 || c == -16))
c = 0;
But without it, it won't stop after pressing SHIFT again. |

| Okay, it moves now, but it only moves 16 pixels down and then it stops. Any suggestions? |

It's probably a debouncing issue. See if that helps.

I'm not really getting a straight answer from Google, so can you tell me what debouncing is?
Edit: Never mind. I know what it is. I still don't know how to fix it though.
Edit2: Fixed it. |

Great job, debouncing can actually be one of the harder things to get right for a beginner programmer. Glad to hear you managed to work it out on your own.

Okay, new project.
Code:
int main() {
while(1) {
int key = PRGM_GetKey();
if(key == KEY_PRGM_MENU) { GetKey(&key); }
Bdisp_EnableColor(1);
CopySprite(TTTVertical, 56, 0, 5, 56);
CopySprite(TTTVeritcal, 56, 61, 5, 56);
CopySprite(TTTVertical, 56, 122, 5, 56);
CopySprite(TTTVertical, 117, 0, 5, 56);
CopySprite(TTTVertical, 117, 61, 5, 56);
CopySprite(TTTVertical, 117, 122, 5, 56);
CopySprite(TTTHorizontal, 0, 56, 56, 5);
CopySprite(TTTHorizontal, 61, 56, 56, 5);
CopySprite(TTTHorizontal, 122, 56, 56, 5);
CopySprite(TTTHorizontal, 0, 117, 56, 5);
CopySprite(TTTHorizontal, 61, 117, 56, 5);
CopySprite(TTTHorizontal, 122, 117, 56, 5);
Bdisp_PutDisp_DD();
Bdisp_AllCr_VRAM();
}
return 0;
}
It keeps saying that TTTVertical is undeclared. I put it in the included "TTTData.h", but it still isn't working. Any suggestions? |

Do you actually have '#include "TTTData.h"' at the top of that file somewhere? Can you paste us the source of the file, but omitting all of the sprite data for brevity?

Also, put your data file under the data/ or include/ directory as specified in the Makefile; if you put it in src/ it may cause errors.

Here is the full with includes:
Code:
#include "keyboard.hpp"
#include "color.h"
#include "display.h"
#include "keyboard_syscalls.h"
#include "TTTData.h"
void CopySprite(const void* datar, int x, int y, int width, int height) {
color_t*data = (color_t*) datar;
color_t* VRAM = (color_t*)0xA8000000;
VRAM += LCD_WIDTH_PX*y + x;
for(int j=y; j<y+height; j++) {
for(int i=x; i<x+width; i++) {
*(VRAM++) = *(data++);
}
VRAM += LCD_WIDTH_PX-width;
}
}
int PRGM_GetKey(){
unsigned char buffer[12];
PRGM_GetKey_OS( buffer );
return ( buffer[1] & 0x0F ) * 10 + ( ( buffer[2] & 0xF0 ) >> 4 );
}
int main() {
while(1) {
int key = PRGM_GetKey();
if(key == KEY_PRGM_MENU) { GetKey(&key); }
Bdisp_EnableColor(1);
CopySprite(TTTVertical, 56, 0, 5, 56);
CopySprite(TTTVeritcal, 56, 61, 5, 56);
CopySprite(TTTVertical, 56, 122, 5, 56);
CopySprite(TTTVertical, 117, 0, 5, 56);
CopySprite(TTTVertical, 117, 61, 5, 56);
CopySprite(TTTVertical, 117, 122, 5, 56);
CopySprite(TTTHorizontal, 0, 56, 56, 5);
CopySprite(TTTHorizontal, 61, 56, 56, 5);
CopySprite(TTTHorizontal, 122, 56, 56, 5);
CopySprite(TTTHorizontal, 0, 117, 56, 5);
CopySprite(TTTHorizontal, 61, 117, 56, 5);
CopySprite(TTTHorizontal, 122, 117, 56, 5);
Bdisp_PutDisp_DD();
Bdisp_AllCr_VRAM();
}
return 0;
}
Edit: I think I know why now. I think it is because I'm trying to use the same sprite over and over again.
Edit2: Can anyone help me with this? |

That should not be a problem at all. Can you please post us the source of the sprites file, as I requested in my preceding post (but please omit the actual sprite contents)?

Code:
const color_t TTTX[5000] = {
};
const color_t TTTVertical[560] = {
};
const color_t TTTO[5000] = {
};
const color_t TTTHorizontal[560] = {
};
Here is TTTData.h without sprite data. |

That all looks fine to me. And it doesn't complain about TTTHorizontal being undefined? Are there any other errors, like it not being able to find TTTData.h?

Code:
main.c: In function 'main':
main.c:30:16: error: 'TTTVeritcal' undeclared (first use in this function)
main.c:30:16: note: each undeclared identifier is reported only once for each fu
nction it appears in
make: *** [main.o] Error 1
That is what it says. |
