just to be sure, top left = 0 right? or do they do it the weird way with bottom left = 0? (Screen cords)

Relys i tried to insert your touch code into a test homebrew. Here's my program.c:

Code:

#include "program.h"
#include "draw.h"
 
//For ctrulib
#include <3ds\types.h>
#include <3ds\services\hid.h>
#include <3ds\gfx.h>
 
//For sprintF
#include <stdio.h>
 
void program()
{
touchPosition myTouchPosition;
 
//As you can see touchPosition is a struct comprised of two 16 bit unsigned integers.
//typedef struct
//{
//    u16 px, py;
//} touchPosition;
 
//Pass pointer to hidTouchRead function which updates values.
hidTouchRead(myTouchPosition);
 
//Read x cord
u16 posX = myTouchPosition.px;
//Read y cord
u16 posY = myTouchPosition.py;
}

I'm getting build errors. Here's the log:

Code:

Could you tell me what have i done wrong?

hidTouchRead(&myTouchPosition);

And to print the posx and posy? Like "TouchX = %d". Can i use %d? I think not.

Bond697 · Nov 20, 2014

if you're using that drawString thing, you'd use sprintf to write the number to a buffer.

sprintf(buffer, "TouchX= %d ", posX);?

Ok, I have set up a VM now, but when I try to Build ctrulib with make clean and make I get an error.
C:\devkitPro\libctru>make clean
make: echo: Command not found
make: *** [clean] Error 127
and
C:\devkitPro\libctru>make
make: make: Command not found
make: *** [build] Error 127
I added the enviroment variables and installed everything as said in the instructions on 3dbrew, but I cant find the error :/

I've got always same errors for compil...

'arm-none-eabi-strip' n'est pas reconnu en tant que commande interne
ou externe, un programme exécutable ou un fichier de commandes.

Check to make sure arm-none-eabi-strip is working. I think it is missing from your path. You need to strip your elf before you use makerom to build it into .3DS/.CIA.

OK arm-none-eabi-strip it's good, problem came Path. I have add PATH = c:\devkitPro\devkitARM\bin; and it's works for me...

Thanks...

Wait what

Code:

error: cannot convert 'gfx3dSide_t' to 'gfxScreen_t' for argument '8' to 'void drawString(char*, int, int, char, char, char, u8*, gfxScreen_t)'
  drawString(buffer, 5, 28, 255, 255, 255, screenTopLeft, GFX_LEFT);

Everything seems to be fine on my side:

EDIT: OOOOOPPPPPSSSS My mistake. I tought this was a reply to my thread...

Is it on the github repo?

wait a second, shouldn't "gfxSwapBuffersGpu();" be enough?

https://github.com/smealum/ctrulib/blob/master/examples/sdmc/source/main.c#L92

You may be right.

@AlbertoSONIC can you see if this is the right way to do it? It would be a lot cleaner.

tankgrrrl · Nov 20, 2014

Just a heads up to anyone having this issue, you have to log off your account then back on for changes to environment variables like PATH to take effect...

Hmmmm, for Windows you should only need to open a new console. :/

Cool, also I added you on Skype if you want to chat right now to try to get screen saving to SD card. I think the code I posted in your thread should be almost right, but I don't currently have a 3DS to test it out on. D:

Could you tell me which file/ line is this code located at?

I haven't looked into 3ds hb yet, does it take much work to build old devkitpro ds projects to work on 3ds?
