Hi,

Im using DLP3000 and i facing a DMD park issue.

Is it possible to make the DMD park using hardware control instead of software command?

Thanks.

Hi XH Low,

Make PWRGOOD I/O (Pin B8) of DLPC300 to LOW, this will cause the controller to put DLP3000 in DMD park state. Similarly setting PWRGOOD = HIGH, unpark the DMD.

Hi XH,

I would like to correct signal details with reference to DLPC300 controller datasheet.

As mentioned above referring to DLPC300 controller datahseet Rev B http://www.ti.com/lit/ds/dlps023b/dlps023b.pdf section Table #3, note the B8 I/O line is now called as PARK signal. Also it is a ACTIVE LOW signal.

Please use this information.

Sanjeev
