Touch input has stopped working here. I'm porting some code I had to the latest devkitpro, and now this wont work:
| Code: |
//Scan key states
scanKeys();
//Current touch position
touchPosition touch;
touchRead(&touch);
if ( keysHeld() & KEY_TOUCH ) {
//do something
|
touch.px and touch.py is always zero :(
Is there something wrong in the above code, or should I look elsewhere for a solution?

On hardware? Or which emu?

Both hardware, no$gba and NDeSmuME. The TouchTest example from devkitpro works on both and hardware and no$gba, but not in NDeSmuME).

Did nobody experience something like this? I must be forgetting to do something somewhere - I just don't know what :(
Perhaps something makefile related?

make sure you are not using irqInit() on the arm9 side - it gets called before main now. if you call it in your code it breaks the default FIFO implementation. are you using the default arm7 or are you using custom code? the touch info is sent to the arm9 using FIFO in the latest libnds so it requires the newer arm7 code.
also, what is Ndesmume? how old is it and does it support FIFO? the current version is called desmume at http://desmume.org

Thanks - that did it! irqInit() was the culprit.
Hmm, that new emulator wont work with my game - maybe I'm doing something else wrong as well?

what is the problem? if you are using libfat then you need to make sure you are using the dlditool to add the "GBA Movie Player (Compact Flash)" dldi driver. the new libfat does not have any drivers builtin any longer.

I'm using EFS when running on emulators and libfat when running on hardware. Works fine on hardware and no$gba, so I'm okay for now. Just curious why it wont work in that new emulator as well.
