Hi all,
I'm doing a project on image processing. I use the CMOS sensor to
capture the images. In the cmos sensor main function, I only find the
Initialization PLL, EBIU, SDRAM, then the I2C Init, and some I2C read
& write registers. then the DMA&PPI init, but when the DMA transfer
starts? and where it put the data?
I'm a newbie in DSP, I just have a little sence in Visual DSP++.
Thank you in advance.

Hi,
Which processor are you using or which hardwere are you using.
Genrally images are stored in external memory.
ADI's Blackfin puts capture image in SDRAM.

Naresh.

Hello
Look the ee-258 Engineer to engineer note 258.
Interfacing Micron MT9V022 Image sensors to Blackfin Processors.
Good Luck.
