DLPC3479: Can DLPC3479 send a trigger out signal when internal pattern completes one time projection

Hi TI's Gays

I am a system engineer from Wintech which is TI' important third party

https://www.wintechdigital.com/PRO4710

We have developed several products using TI's DLPC3479

Now we are developing new DLPC3479 device for AOI and SPI

Our 3D AOI device uses 4 DLPC3479 optical engines installed in four directions, for example represented by  A-B-C-D 

Four devices are working at internal pattern mode and free running mode

Each device will play once if geting start control command,for example W 36 9E 00 00, from IIC control interface

Four Trigger out2 signals, output from each device,  are connected together to trigger camera 

Four DLPC3749 devices project pattern image in turn, For example first from A to second B to third C to last D

So I run into a difficult problem , When should the next device be notified if the current device completes the patterns 

I add a MSP430 into the hardware system and MCU can send DLPC3479 command from IIC interface

Also, I have connected both four  DLPC3479 Trigger Out1 signals and Trigger Out2 to MCU GPIOs

What I want to know:

How can I change the function of Trigger Out1, to the status of completed patterns projection from the begining of the pattern set

Or

How can I add another Trigger Out3, which will be sent out when all the patterns are projected

 The "TIRef-DLPC3479-DLPA3005-AC_Only-CurrentLimitsRemoved-BlueOnly-v8p1p001" and "TIRef-DLPC3479-DLPA3005-TIEVM-CurrentLimitsRemoved-v8p2p0"

DLPC3479 composer projects zipped files were shared with me from   Austin Snyder  and Arthur Brown

Could you share me app347x_dual_v4.4.0.bin file all-in-one source and I can modify the source code by myself

PS: 

I have experience in modifying DLPC442x all-in-one source code, I think I have the ability to modify the API sound code of DLPC3479

Thank you very much

Best Regards
