DLPDLCR2000EVM: Turn DMDs ON and OFF with the LED light on

TALIA XU

Part Number: DLPDLCR2000EVM
Other Parts Discussed in Thread: DLP2010, DLPC3430, DLP2000, DLPC2607

Is there a function that allows turning the DMDs ON and OFF while keeping the LEDs ON? DPP2607_Write_DmdPark() seems to control both the DMD state and the LED state simultaneously (because absolutely no light comes out of the opic engine, unlike DLP2010).

Thanks!

Mayank,

Since the DLP2000 DMD is being driven by the DLPC2607 in this case (unlike the DLP2010 with the DLPC3430 controller) the command suite and respective behavior is not identical between DMDs. There is not a second command to park the DMD that behaves in the way you are describing.

For a full list of I2C commands, refer to the DLPC2607 programmer's guide:

I hope this helps.
