Memory on dev kit vs image size

[Ricko]

Hi,

looking at this dev kit  https://www.st.com/en/evaluation-tools/32f469idiscovery.html#overview

it comes with a 800x480 pixels display and the QSPI is "only" 128Mbit.

Am I correct in saying that (without any compression) it can only store just over 10 full screen-sized images assuming 4 bytes per colour (1 layer with transparency)?

128,000,000 / (800 x 480 x 32) = 10.4

That also means no video can be stored (unless you just play a few frames)?

Is that correct or am I missing something?

Thank you :)

I tend to agree with you in case unpacked video used.

If packed video used like MJPEG, video (400x240 size or smaller) may be played back - like the case for some kind of demo from ST.

Video is likely to be a challenge, as you have no CODECs

For larger memory, perhaps Micro SD card.
