DLPLCR9000EVM: External trigger

Prodigy 60 points

Part Number: DLPLCR9000EVM

Hello.

I tried to put external trigger into my DMD, but failed. 

I am using 51021-0600 for connector and 50079-8100 for crimp. 

I put a rectangular wave which is 1kHz, and 3.3V, but it didn't work. 

So I checked whether trigger out was working well or not. 

Checked by the oscilloscope, it also didn't work. 

It can be a connector problem? If not, what should I do then?

Thanks. 

 

  • Hi Ryu,

    Could you please tell me in which mode are you running the controller?

    Also, do you have your own software or are you setting up using the provided GUI?

    Thanks

    Thanks for the reply. 

    I am using the provided GUI and the mode is pattern on-the fly. 

    I also checked the trigger input and output. Of course, after checking, update the LUT. 

    Thanks.

    Hi Jihee,

    Please make sure you are clicking the select all the patterns before uploading as shown in the below snap after checking the trigger input and outputs.

    If this is ok, then please make sure the position of J22 jumper is connected between (1 and 2) and not on (2 and 3)

    Also, could you please provide information about the point you probed in the EVM to check the trigger input? I am able to read the Trigger pulses at the connector and TP15

    Thanks

    Hello. This is Jihee. 

    I solved. External trigger worked perfectly. 

    I put the jumper in the wrong position. 

    Thanks for your help. 

    Jihee.

    Thats great Jihee!

    Please make sure the same connection for J24 as well if you need to use the second trigger input pin

    Thanks

    Sachin
