hi,expert
i have experience in developing dm365/dm368 with cmos sensor .i want to config ccd sensor for my dm365 board now.i know i can use some ti chip such as tvp5146 for captureing image for ccd camera.but that is not my want.
i would like use some sony ccd module which embeds CXD3191R on it for dm365 video interface.now i know the cxd3191r can output bt601 16bit data for video interface.i can connect Y0-Y7 C0-C7 HSYNC VSYNC CLK pins to dm365 video interface directly in signal.but i dont know how to write driver for cxd3191r.
it is hard to get cxd3191r datasheet and it is difficult to find ccd dsp driver in linux .it is hard to understand why there is no driver for sony ccd chip in linux dvsdk.as we know ,sony is the largest company for camera chip design.and her ccd dsp chip has both analogy output and digital output generally.why we often use tvp5146/tvpxxx to capture analogy signal ,and not use ccd digital output signal?Is it unnecessary for driver in dvsdk?maybe i am wrong.it is my question.
if i could use standard protocol or method to complete this task,for example v4l2 and ...,it is great.could anyone tell me how to write ccd dsp driver in linux.on this forum,there are many posts for cmos sensor driver,but no ccd driver.could any expert give me some light or example?thanks
