I have a monochrome sensor which requires a new device driver to the DM8148. We are going to use the Z3 Tech board initially.
Our camera module has a 12 bit parallel interface with 640 x 512 resolution and pixel Master rate of < 10MHz. After some image processing I need to display the processed frames on HDMI or SD display.
I'm using the Appro IPNC GA version 3.00.00 to evaluate while waiting for the actual DM8148 devices to arrive. Please help me on the following:
1. With the correct defconfig files I should be able to port all software from DM8127 environment to DM8148 environment, correct? I have these from another forum thread. Or do I go the EZSDK route.
2. What is the file name to write the low level sensor driver in. I have been looking at 'issdrv_captureApi.c'. What other files should I be focussing on? I am only interested in the RAW image data, no YUV transformations. Where do I set-up fps, width, height, pixel clock rate and 'raw image mode'
3. I'm using the Smart Analytics usecase as a reference. What is the correct method of 'routing' the frames to the HDMI output after all processing has been done. ie, after the face tracker and DSP algorithms have been implemented. Should I create a frame duplicator after IPCM3OUT (M3VPSS) to create another branch/stream?
4. Where is the best section(src filename) in the code to do DSP specific functions?
Thanks!
