Hi,

I have tested small project with mikromedia HMI 7".
For calculation I have used TimerA 1ms.
Time to write screen is less than 1.6ms.

Note, that for the picture 800x480 external memory is necessary. I was using SD card as a storage for picture.
If you want I can share the code with you.

Kind regards,
Aleksandar

Hi Aleksander.

I have a question. You wrote that ,time to write screen is less than 1.6ms.
I have an image with size 1.37mb. Maximum speed SPI - 30Mh(between FT900 and FT812).
1.37mb = 11223040 bit
1/30Mh=33.34 nsec per bit
33.34nsec * 11223040 bit = 374msec

How do you get speed is 1.6msec?

Thank you!
