DLPDLCR2000EVM: DLPDLCR2000 lens focus adjustment through software

Part Number: DLPDLCR2000EVM
Other Parts Discussed in Thread: DLP2000

Hi,

Is there any provision to adjust the focus of the lens of DLPDLCR2000EVM through software?if not, is there any dlp projectors available which has the option to adjust focus of the lens through software?

Also, in the DLP2000 DMD datasheet, a block diagram (section 8.2) shows a stepper motor and motor driver block connected to GPIO5. Is this present in the EVM and can be used for focus adjustment? please clarify on this.

Hello Ajeel,

Welcome back to the E2E forum. Thank you for your continued business!

If your application uses focus motor control with a sensor, you may use GPIO5 as an input pin to connect to the motor position sensor. If your application does not use non-focus motor control with a sensor, configure this pin with an output at logic 0 and leave it unconnected. See the DLPC2607 controller datasheet for more information.

Best,

Maxine

Hello Ajeel,

Unfortunately we do not offer any off the shelf products with a motor controlled focus.

Kind regards,

Austin
