Dear all
I want to start using emWin graphical interface on LPC1788. I have come here to use your invaluable experiences. The main question: is internal flash memory and SRAM of LPC1768 (512 kB of flash memory and 96 kB of SRAM) enough for getting both RTX and emWin up running or do I need to add external RAM?
I will use an SD memory card to store pictures and anything of that nature.
Thanks a lot
O, my mistake. it is LPC1788. 68's SRAM is 32kB.
"I want to start using emWin graphical interface on LPC1788 ... is internal flash memory and SRAM of LPC1768 enough ..."
So which is it - LPC1788, or LPC1768 ?
You need external SDRAM as the frame buffer for the LCD controller of LPC1788.
Let's say you want to use a 200x100 4 color LCD, 200*100*4/1024=78KB
