Here is the call graph for this function:

void lc_close ( )

The close function.

Returns:: NOT_CONNECTED_ERROR or return state of the usb_close function.

{
    if (_lc_handle == NULL)
        return NOT_CONNECTED_ERROR;

    return usb_close(_lc_handle);

}

void lc_init ( )

The init function.

Returns:: SUCCESSFULLY_CONNECTED or DEVICE_NOT_FOUND_ERROR.

{

    usb_init();

void lc_saveFrame	(	unsigned	long,
		int
	)

void lc_setFrame ( unsigned long frame )

The setFrame function.

Parameters:

frame The 32bit frame data. Bit 0-8 equals layer one; bit 9 - 17 euqals layer two; bit 18 - 26 equals layer three. the 5 MSB is the lifetime of the current frame in ISR calls (300Hz).

Returns:: NOT_CONNECTED_ERROR or the return value of the usb_control_msg function.

{

    if (_lc_handle == NULL)
        return NOT_CONNECTED_ERROR;

    int low  =  frame & 0xffff;
    int high = (frame & 0xffff0000) >> 16;

    int ret = usb_control_msg(_lc_handle, USB_TYPE_VENDOR | USB_RECIP_DEVICE | USB_ENDPOINT_OUT, CUSTOM_RQ_SET_FRAME,  low, 0, _lc_buffer, 0, 300);
    ret += usb_control_msg(_lc_handle, USB_TYPE_VENDOR | USB_RECIP_DEVICE | USB_ENDPOINT_OUT, CUSTOM_RQ_SET_FRAME, high, 1, _lc_buffer, 0, 300);

    return ret;
}

void lc_setMode ( int mode )

The setMode function.

Parameters:

mode	The firmware mode. MODE_ANIMATION_STOP; MODE_ANIMATION_SINGLE; MODE_ANIMATION_LOOP

Returns:: NOT_CONNECTED_ERROR or the return value of the usb_control_msg function.

{
    if (_lc_handle == NULL)
        return NOT_CONNECTED_ERROR;

    return usb_control_msg(_lc_handle, USB_TYPE_VENDOR | USB_RECIP_DEVICE | USB_ENDPOINT_OUT, CUSTOM_RQ_SET_MODE, mode, 0, _lc_buffer, 0, 300);
