How to quick start to process VPIF raw data in DSP?

Hi Changsheng,

Thanks for your post.

To capture raw data in dsp thru. VPIF, you need to configure the LCD controller in LIDD mode instead of raster mode. Usually, raster mode is configured in raster controller to capture and display image over LCD but to capture raw character/text display, you need to configure the code in LIDD mode in the display controller.

In order to configure LCD in LIDD mode for interfacing character/text display, alternatively you could refer OMAPL138 starterware vpif_lcd_loopback examples, but by default the LCD controller is configured in raster mode in this code. To get you the reference to configure the LCD in LIDD controller mode, you could use the source file liddDisplay.c in the same starterware package from the below path, after installing the starterware pacakge:

~\OMAPL138_StarterWare_1_10_03_03\examples\evmOMAPL138\lidd\liddDisplay.c

and for raster display, you could refer the below source file

~\OMAPL138_StarterWare_1_10_03_03\examples\evmOMAPL138\lidd\rasterDisplay.c

Please refer SetUpLCD() function in the above source files to configure in Raster/LIDDmode.

In general, to refer  vpif_lcd_loopback example in the OMAPL138 starterware package, you could see the below path:

~\OMAPL138_StarterWare_1_10_03_03\examples\evmOMAPL138\vpif_lcd_loopback\vpif_lcd_loopback.c

To download the OMAPL138 Starterware software, you could write the code to capture raw data thru. VPIF by referring the above mentioned examples & source files to configure in LIDD mode.

Hi Sivaraj Kuppuraj:

    Thanks very much!

    Does DVSDK4.03 can do that?

    Thanks.
