I'd love to have 8GB of RAM. The SOC I'm working with has only 2K ;-)
Bet your compiler isnt running on that hardware either ;-)
Luckily, no ;-)
2 kilobytes?
Yes. 2 kilobytes. Coincidentally, this is as big as the displays internal buffer, so I cannot even keep a shadow copy of it in my RAM for the GUI.
Thanks for clarification.
I've never seen backbuffer called shadow copy.
And I have never heard it called "backbuffer", so we are even.
I guess so.
Example: https://www.khronos.org/opengl/wiki/Default_Framebuffer#Double_buffering
EDIT: Wait. Do you have framebuffer at all? Because from sounds of it, you might not even have it at all. If you don't store entire frame in RAM, then you don't have framebuffer, not just backbuffer.
I never said anything about framebuffers. The 256x64 pixel display in 16 brightness levels probably has something comparable inside. I just tell it that i want to update a rectangle, and send it some data for that.
It should have.
Then, if you don't store contents of entire screen in memory, which simple math says you can't, I was partially wrong(depending on if you don't count buffer in display as framebuffer) when interpreted "shadow copy" as backbuffer.
Come on, man, AVR chips aren't SoCs except in the technical sense.
No AVR, it's a small LPC from NXP. Chosen for the price, of course, but I have to somehow squeeze the software in it. At this point, even 8k would make me happy...
NXP, fancy. I expected ST, AVR, nRF, WCH or some chinese cheaptroller.
Why them? Something to do with NFC?
Man, microcontrollers are namegivers of SoC.
