Hello Cherry,

Thank you for reaching out to us.

Can you find the Cheetah Adapter in your Device Manager? If not, please download the drivers for the Cheetah SPI to USB adapter from https://www.totalphase.com/products/usb-drivers/

Thank you,

With regards,

Hello Aishwarya,

Yes,I can find the Cheetah Adapter in my Device Manager and it works well.Also I can find it in the control program,but also exists communication error.

Cherry,

Few suggestions:

1. Is the system powered on? Is the PROJ_ON switch turned on?
2. Does the SPI communication parameters match the configuration in your flash? Check in 'Communication Settings'

Thank you,

Aishwarya,

Yes

1.the system is powered on,and the Projector ON switch turned on.

2.OK,I will check it right now

Hello Michael,

I hope this message finds you well.

I make a checklist and step by step to check the issue is,and finally I find the problem is the DMD board is damaged which causes a disconnection between the cheetah and my PC,so I can't use my PC to control the module and change the image pattern.So there exsits a communication error as shown below.

So,the next time I will chage another one DMD board to try again,any progress I will feedback to you. thanks!

Best & Regards

Hi Cherry,

May you please try the following?

1. With EVM powered off, disconnect DMD from board
2. Connect host adapter from EVM controller board to host computer. Please try direct connection and avoid usage of any external USB hub if you are currently using one
3. Power on the EVM
4. Close all instances of DLPC230 Control Program and then open a new instance
5. Use Connection tab in the DLPC230 Control Program software to connect
   1. Does the system mode go to standby or does it go to communication error?
   2. If this goes to standby, your SPI cable works
   3. If this is a communication error, something could be wrong with your SPI communication--probably hardware related such as bad cable or something on the board is damaged or defective

I also see a lot of thermal paste on the image you shared. Is there any chance this DMD has been reseated many times or at least one other time in the past?
If so, I would make sure that none of the pins get thermal paste on them. This can cause major connection issues if inserted into the DMD socket. If the socket gets any thermal paste in it, it may become difficult to clean out and make proper connections with DMD pins in the future. Please make sure this is always checked and cleaned when reseating or installing new DMDs.

Hi Michael,

Sorry for the late reply,these days I'am working on another project so I have no time to update the progress of verification information.

Updating as follows:

1.I have followed the steps as you describle,when I used Connection tab in the DLPC230 Control Program,the system mode go to communication error,so the SPI cable doesn't work.

2.The next time I intend to change a new one DMD & a new one SPI cable to try again.

3.Yes,the DMD was inserted and unplugged at least two times,but every time when I unplug it I will change a new one piece of thermal pad ensure of enough

heat dissipation,and by checking the DMD socket there is no thermal paste in it and in the future I will keep it in my mind(make sure the DMD socket is always checked and cleaned when reseating or installing new DMDs. Thanks for reminding.

I hope the DMD board is OK,otherwise it will take a long time to make a new one.

Thank for the information you advise,I will update the verification information ASAP maybe I can finish this week,pls wait my good news!

Best & Regards

Michael,

I don't have a second SPI adapter cable at present,so the next time I will try to control it according to your advice,I hope it can success

The white connector on the right (J3) ,is that one as follows?

Michael,

Very detailed,I completely understand,thank you so much!

In fact,I have the materials in the zipped file that you gave me,which you can find in the picture below.

Don't worry about it,I got it.And I have the wire harness uses the 5013300700 on both ends,it matches the pin out from the SPI Adapter Board to the DLP5530Q1EVM correctly,I will try to control the EVM again and confirm the system mode goes to standby or goes to communication error.

Hopefully everything can solve!

"Let me know if any other help is required--I'm happy to help!" Thanks a lot and your patience!

Cherry,

That's great!! I hope to hear back soon.

That's awesome!! I'm very happy that it was just a simple issue with the cable and not something else.

Thank you for the good wishes!
