VPIF OMAP L138

Other Parts Discussed in Thread: OMAP-L138

Hello,

I have LCDK Omap L138 board. I have a camera sensor OV5640. I want to send data to VPIF and later to LCD. I send data from the sensor in RGB565 format, write it to a memory and send to the LCD. I can see some colors, strips etc. but no image. I use Raw data format in VPIF. Maybe I should send data from the sensor in other format? I can send my project to someone to check quickly my code.

Thanks,

    Hello,

    Thank you for answer. I have seen this example. In this example we have to set 2 addresses LUMA and CHROMA for top and bottom field. In raw mode have I do this or I should only set address LUMA TOP and BOTTOM for CH0 and CH1? I want to get 10-bit data from my sensor. I get data in RGB565 format or in YUV422. In the example we connect a camera with composite signal. We use codec and we transform YCrCb to RGB565. I do these steps in my project in raw mode but it doesn't work. Can I just it send to LCD or I should do something more? Some conversions? Please help. What I get on LCD is below. Is there on this forum someone who did raw mode? I saw many questions but few answers. I can send my project to someone who wants to help.
