DLPC3438: Changing Pixel clock capture edge?

AnBer

Part Number: DLPC3438
Other Parts Discussed in Thread: DLPC3433, DLPC3430

Team,

In the datasheet of the DLPC3438 DLPS035C –FEBRUARY 2014–REVISED DECEMBER 2016
page 7, there is a small note that says : (3) Pixel clock capture edge is software programmable.

-Where to find reference on how to do it? There is no other references in neither the datasheet nor in the programming guide.
-How can we change the edge of PCLK ?

Thanks in advance,

Please see Command 0xB6 in the Software Programmer's Guide "Write Parallel Interface Sync Polarity" for the command referenced in this documentation.

I hope this helps.

Hello,

NOPE. This register is for HSYNC and VSYNC, not for Data !

As the datasheet says page 7 : (3) Pixel clock capture edge is software programmable

On my understanding, that means that the pixel clock used to qualify the data can be change ?

Right ?

Thank you

Hello ,

The only VSYNC and HSYNC polarity can be adjusted by software. The DLPC3433/8 datasheet is under revision and this information will corrected in future version.

The DLPC3430/5 datasheet is updated version. The features and interface of this controller is similar to DLPC3433/8. Please refer to the page 9 of DLPC3430 datasheet and the information has been updated in this datasheet.
