This lib has been tested and works. for any bug report, please write to me on github or send me an email.

libmove for PSL1GHT V2

This lib will be installed inside the PORTLIBS

Example

	#include <libmove/libmove.h>
	int main(s32 argc, const char* argv[]){
		movePadData data;
		init_move();
		while(1){
			getMovePadData(&data);
			if(data.BTN_ACTION)
				calibrate_move();
			}else if(data.BTN_T){
				goto end;
			}
		}
	end:
		end_move();	
	}

Shortly following, deroad has also made available a PS Vibe Move Edition stating the following:

This homebrew should be only for ladies.. well what it does? it simple enable the rumble on the PS Move. you can choose the intensity with the trigger and then press the action button to keep that.. this homebrew should work on any TV.

v1.01 Changelog:

• Fixed the blackscreen issue. now it should work.

What is libmove ? (via psxbrew.net/wiki/How_to_use_libmove)

Is a simple lib that allows to use the PlayStation Move controller on the PS3 through PSL1GHT (V2). This lib works only with the PlayStation Eye.

How to use it

Include

It's quite simple to use. First thing is including the lib into the source code.

#include <libmove/libmove.h>

You don't need any other header. that one include all the things.

Initialise libmove

then you need to initialise it:

initLibMove();

This function return LIBMOVE_ERROR if something went wrong. If everything is fine, that returns LIBMOVE_OK. This can be an example of how to use this:

if(initLibMove() == LIBMOVE_ERROR){
//Something went wrong
return -1;
}else{
//Do something..
}

End libmove

To stop the lib, you can simply call this function. it will return LIBMOVE_ERROR if something went wrong. If everything is fine, that returns LIBMOVE_OK.

initLibMove();

Get Gyroscope values

To get the gyroscope values (x,y,z axis) you can use this function:

float x ,y ,z;
getGyroPosition(PLAYSTATION_MOVE_PAD_0, &x, &y, &z);

This piece of code return the x,y,z float value from the first ps move connected. You can use this function to track a cursor into the code in this way:

//outside the loop:
float x = screen_width/2 ,y = screen_height/2 ,z = 0; //this to get the pointer to the centre of the screen
 
// inside the loop
float x1 ,y1 ,z1;
getGyroPosition(PLAYSTATION_MOVE_PAD_0, &x1, &y1, &z1);
//all the gyroscope values when the move is not moving, are lower then -+2
//this means that when you move the controller you get higher values then abs(+-2) = +2
if(abs(x1) > 2)
x += x1;
if(abs(y1) > 2)
y += y1;
if(abs(z1) > 2)
z += z1;
//in this way you update the values with the new position only if you are actually moving the controller

Get the real position of the controller

you can get the controller position also through the 3D position:

float x ,y ,z;
getGyroPosition(PLAYSTATION_MOVE_PAD_0, &x, &y, &z);

this time you get the ball position compared to the distance from the Playstation Eye.

Calibrate the controller

Calibrating the controller is quite simple. you need only need to know what controller and then call this:

calibrateMove(PLAYSTATION_MOVE_PAD_0);

Get controller buttons

To get the controller buttons, you need to know what number of the controller get. In the example is always the first controller (PLAYSTATION_MOVE_PAD_0).

movePadData movePad;
getMovePadData(PLAYSTATION_MOVE_PAD_0, &movePad);

movePadData is a struct that has the following buttons:

/* Button information */
BTN_SELECT;
BTN_T;
BTN_ACTION;
BTN_START;
BTN_TRIANGLE;
BTN_CIRCLE;
BTN_CROSS;
BTN_SQUARE;
/* Analog nub information */
ANA_T;

All the BTN_* return 1 (true) if the button is pressed, otherwise return 0 (false). An example:

//somewhere in the code
movePadData movePad;
 
//somewhere else in the code
getMovePadData(PLAYSTATION_MOVE_PAD_0, &movePad);
if(movePad.BTN_ACTION){ //if the ACTION button is pressed
//do something
}

There is also the trigger value (ANA_T). This returns a value between 0x00 and 0xff. 0x00 is when is not pressed, 0xff is the max value. You can also use BTN_T to only know if it is pressed or not (it will return 1 also if the value is at the least 0x01, but also with any value between 0x01 and 0xff).

//somewhere in the code
movePadData movePad;
 
//somewhere else in the code
getMovePadData(PLAYSTATION_MOVE_PAD_0, &movePad);
if(movePad.ANA_T > 0x30){ //if the T button is pressed with the intensity of 0x31 or higher
//do something
}

Makefile

To compile with this lib, you need to add the following flags:

LDFLAGS = -lmove -lgem -lcamera -lspurs
