DLPC6540: manual warp command(0x34~0x39) doesn't work on software version 4.4.0

Part Number: DLPC6540

Hi,

This day I test DLPC6540 on software version "dlpc6540_lpcw_v4.4.0", and I found that the manual warp commands (0x34~0x39) doesn't work use with Composer control 15.1.0.37.

The "DLPC6540_Software_v4.4.0_Release_Notes.pdf" note that, the command 0x37 change to use 0x36, but the Composer control 15.1.0.37 with DLPC654x display controller still send the 0x37 on "Read Manual

Warping Enabled" button "Get". It is the Composer control 15.1.0.37 need to be upadte ?

Please help me and waiting for your respond.

Thank you !

Hi User,

You need to generate the command layer form the Tools menu in control program with the appropriate cfg file corresponding to v4.4.0 for the changes mentioned to be reflected

Also Please ensure the product selected in Control Program is DLPC654x controller.

Yes, I sure the product selected in Control Program is DLPC654x controller. I generate the command layer but it did not resolve my issue.

Hi Xinmin

After inspecting the attached cfg file. it is corresponding to version v3.3.0. Please use the latest compatible cfg file corresponding to version v4.4.0

Hi Akhil

The question is where I can download the the latest compatible cfg file corresponding to version v4.4.0 ?

The cfg file I share to you is in the Composer control 15.1.0.37 installed path:

The worst is, I send the i2c commands(0x34~0x39) by mcu system, the projector display warping does not take effect。But I send these same i2c commands by mcu to DLPC6540 V4.3.1, it is work and the projector display warping take effect.
