Hello,
I am working on a project with both a 320*240 SPI touch screen and an OV7670 camera.
Using the arduino libraries, I can make things work...
BUT, the imx seems to have HW assist for both SPI and CCIR656 compatible cameras. Is there any library or anything available to use the HW assist to DMA the screen data out in a (semi) continuous way (so that I can tell the HW: send new framebuffer, and have it being sent using DMA or something like this in parallel with the rest of my processing.
Simillary, I need/want to aquire the camera data in a HW way without having to do it in FW and get an interrupt/message/flag set once a new frame is available.
Thanks,
Cyrille
