 |
|
I'd like to know what is the simplest method of sending data using the IrDA, just like if the PSP was a remote.
I tried sceIoWrite but it doesn't send anything. |

You've got to open the irda device first so you're writing to something.
Straight out of samples:
| Code: |
int main(void)
{
SceCtrlData pad;
u32 buttonsold = 0;
SetupCallbacks();
pspDebugScreenInit();
sceCtrlSetSamplingCycle(0);
sceCtrlSetSamplingMode(PSP_CTRL_MODE_DIGITAL);
int fd = sceIoOpen("irda0:", PSP_O_RDWR, 0);
while (1) {
// read pad and send it
sceCtrlReadBufferPositive(&pad, 1);
if (pad.Buttons != buttonsold) {
unsigned char padHighbyte = pad.Buttons >> 8;
sceIoWrite(fd, &padHighbyte, 1);
buttonsold = pad.Buttons;
}
// check for pad info from other PSP
unsigned char data;
int len = sceIoRead(fd, &data, 1);
int otherPad = data << 8;
if (len == 1) {
if (otherPad & PSP_CTRL_CIRCLE) printf ("CIRCLE pressed\n");
if (otherPad & PSP_CTRL_CROSS) printf ("CROSS pressed\n");
if (otherPad & PSP_CTRL_SQUARE) printf ("SQUARE pressed\n");
if (otherPad & PSP_CTRL_TRIANGLE) printf ("TRIANGLE pressed\n");
}
sceDisplayWaitVblankStart();
}
return 0;
}

How do you know nothing is being sent, rather than the possibility that
the rest of your program is crap?
Have you checked ir with a digital camera or webcam? |
