使用zcl_lighting 如何根据colour X和colour Y 求出RGBW

static ZStatus_t zclLighting_ProcessInCmd_ColorControl_MoveToColor( zclIncoming_t *pInMsg,
zclLighting_AppCallbacks_t *pCBs )
{
if ( pCBs->pfnColorControl_MoveToColor )
{
zclCCMoveToColor_t cmd;

cmd.colorX = BUILD_UINT16( pInMsg->pData[0], pInMsg->pData[1] );
cmd.colorY = BUILD_UINT16( pInMsg->pData[2], pInMsg->pData[3] );
cmd.transitionTime = BUILD_UINT16( pInMsg->pData[4], pInMsg->pData[5] );

if ( ( cmd.colorX > LIGHTING_COLOR_CURRENT_X_MAX ) || ( cmd.colorY > LIGHTING_COLOR_CURRENT_Y_MAX ) )
{
return ( ZCL_STATUS_INVALID_VALUE );
}

return ( pCBs->pfnColorControl_MoveToColor( &cmd ) );
}

return ( ZFailure );
}

获取得到colourX和colour Y ,如何根据这两个值得到RGBW 四个灯的值

xy 到xyY，然后再到RGB，再转成RGBW

 hwLight_UpdateLampColor( uint16 colorX, uint16 colorY, uint8 level)

hwLight_Convert_xyY_to_RGB

hwLight_RGB_to_RGBW

请问这几个函数在哪。没有找到

另外，SAT.HUE.LEVAL 如何转换为RGBW

你要的全在

C:\Texas Instruments\Z-Stack Lighting 1.0.2\Projects\zstack\ZLL\SampleApp\Source\Light\hw_light_ctrl.c
