DLP LightCrafter 9000 EVM over TCP/IP

Other Parts Discussed in Thread: DLP9000, DLPC900

Hi everyone,

we are currently attempting to communicate with the DLP via Labview. After some research in the forum, we found some code that might just do for our purposes (shifting patterns using an external trigger input). In order to do so, we need to communicate to the device using TCP/IP over USB. This is possible since, on this EVM, there is a DM365 embedded processor, to which the PC communicates via TCP using the RNDIS driver (according to the answer I received here https://e2e.ti.com/support/dlp__mems_micro-electro-mechanical_systems/f/850/t/396805 ).

Getting to the problem: I am currently not able to determine the IP of the device, nor the port it uses (both infos are needed to open the TCP/IP connection in LabVIEW, of course).

Any help on this will be highly appreciated.

Thanks,

Mirco

Hi Mirco,

I guess, there is some kind of misunderstanding going on. To my knowledge, and please correct me if I am wrong, there is no such option as controlling the EMV9000 via TCP/IP. The DLP9000 DMD in your evaluation kit is being controlled by two DLPC900 processors. These do only feature low level USB communication via e.g. the HIDAPI library as implemented in the matlab code you stumbled across already. Thus, you would need to implement such kind of communication in your VI. However, before you do so I would advise you to do some estimation on the data rate you require. This is a somewhat limiting factor if you try to transfer tons of data on a human interface device usb channel.

Can anyone of the TI experts comment on this?

Best
Klaus
