Frame rate issue with 800x600 LCD

[oliviermonnom]

Hi,

I've a MIMXRT1064-EVK board and the LCD (480*272 pix) display.

I've a PAL camera and an CCIR656 encoder whose outputs go directly to the CSI interface. DATA flux is about 27MB/s.

I've modified slightly the demo prg to deal with the camera, so far so good, works fine.

Then I changed the LCD for a 800x600pix (with a // to LVDS converter) and I'm facing framerate issue (no more 25fps for the CAM).

Here is the question: is there somewhere a calculation (at least theoretical) of the max resolution possible for a (decent) framerate of 25Hz with the RT10xx and it's associated SDRAM?

Thank you,

Olivier

Hi Olivier Monnom,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) Here is the question: is there somewhere a calculation (at least theoretical) of the max resolution possible for a (decent) framerate of 25Hz with the RT10xx and it's associated SDRAM?
-- Whether you like to know which color space format is appropriate for the 25 fps, if yes, I think RGB888 is a good choice.
