I'd like to add a 2 players feature in my project, but can't succesfully receive data from the second controler.

I init my pads with this:

Code: Select all

    int port = 0; // 0 -> Connector 1, 1 -> Connector 2
    int slot = 0; // Always zero if not using multitap
    if&#40;&#40;ret = padPortOpen&#40;port, slot, padBuf&#41;&#41; == 0&#41; &#123;
        scr_printf&#40;"padOpenPort failed&#58; %d\n", ret&#41;;
        SleepThread&#40;&#41;;
    &#125;
    else&#123;scr_printf&#40;"ok-"&#41;;&#125;

    if&#40;!initializePad&#40;port, slot&#41;&#41; &#123;
        scr_printf&#40;"pad initalization failed!\n"&#41;;
        SleepThread&#40;&#41;;
    &#125;
    else&#123;scr_printf&#40;"ok-"&#41;;&#125;

    port = 1; // 0 -> Connector 1, 1 -> Connector 2
    slot = 0; // Always zero if not using multitap
    if&#40;&#40;ret = padPortOpen&#40;port, slot, padBuf&#41;&#41; == 0&#41; &#123;
        scr_printf&#40;"padOpenPort failed&#58; %d\n", ret&#41;;
        SleepThread&#40;&#41;;
    &#125;
    else&#123;scr_printf&#40;"ok-"&#41;;&#125;

    if&#40;!initializePad&#40;port, slot&#41;&#41; &#123;
        scr_printf&#40;"pad initalization failed!\n"&#41;;
        SleepThread&#40;&#41;;
    &#125;
    else&#123;scr_printf&#40;"ok-"&#41;;&#125;

and 4 "ok" are printed, fine!

but how can I receive data from the second one?

i tried

Code: Select all

struct padButtonStatus buttons&#91;2&#93;;
int port =1;
int slot=0;
int ret 
ret = padRead&#40;port, slot, &buttons&#91;port&#93;&#41;; // port, slot, buttons

    if &#40;ret != 0&#41; &#123;
        paddata&#91;port&#93; = 0xffff ^ buttons&#91;port&#93;.btns;

        new_pad&#91;port&#93; = paddata&#91;port&#93; & ~old_pad&#91;port&#93;;
        old_pad&#91;port&#93; = paddata&#91;port&#93;;

        i=new_pad&#91;port&#93;;
    &#125;

    paddata&#91;port&#93; = 0xffff ^ buttons&#91;port&#93;.btns;
    i=paddata&#91;port&#93;;

but then

Code: Select all

    if &#40;i&PAD_TRIANGLE&#41; &#123; ... &#125;

just never works...

From a quick glance at your description and code I can't spot the problem. I suggest you try the 3 different pad samples in ps2sdk (rpc/pad, rpc/padx, rpc/mtap) and go from there.

Thanks, Lukasz,
I've found my error in those examples:
You need to have 2 padBuf, so the code has to be:

Code: Select all

static char *padBuf&#91;2&#93;;
    padBuf&#91;0&#93; = memalign&#40;64, 256&#41;;
    padBuf&#91;1&#93; = memalign&#40;64, 256&#41;;


...



    int port = 0; // 0 -> Connector 1, 1 -> Connector 2
    int slot = 0; // Always zero if not using multitap
    if&#40;&#40;ret = padPortOpen&#40;port, slot, padBuf&#91;0&#93;&#41;&#41; == 0&#41; &#123;
        scr_printf&#40;"padOpenPort failed&#58; %d\n", ret&#41;;
        SleepThread&#40;&#41;;
    &#125;

    if&#40;!initializePad&#40;port, slot&#41;&#41; &#123;
        scr_printf&#40;"pad initalization failed!\n"&#41;;
        SleepThread&#40;&#41;;
    &#125;

    port = 1; // 0 -> Connector 1, 1 -> Connector 2
    slot = 0; // Always zero if not using multitap
    if&#40;&#40;ret = padPortOpen&#40;port, slot, padBuf&#91;1&#93;&#41;&#41; == 0&#41; &#123;
        scr_printf&#40;"padOpenPort failed&#58; %d\n", ret&#41;;
        SleepThread&#40;&#41;;
    &#125;

    if&#40;!initializePad&#40;port, slot&#41;&#41; &#123;
        scr_printf&#40;"pad initalization failed!\n"&#41;;
        SleepThread&#40;&#41;;
    &#125;

now it works :)

Thanks for letting us know what it was that worked. Too often you see people post that they worked out the problem, but not what the solution was, and that doesn't help anyone.
