Hi

Recently I downloaded Emwin 5.18 .After following appnotes for customizing the an HX8347D display i made compilation to "hello world". Memory used was about 40 K.
I tried several configurations but nothing changed only very small differences were observed .Can anybody give me a clue why this is happening ?.Are there any hidden switches that are not referenced in APPNOTES ?.
Manual states a hello world about 5.2 K .Has anybody managed such memory sizes ?.
Can we take advantage of the EMWIN GUI for 64-128K LPC17xx devices ?.
Initial results in every example I tried were discouraging using 60-100 K for simple GUI's .
So any other thoughts about it ?.

Hi Leonardo,

That seems about right.

The problem is that the libraries are compiled with all supported features (window manager, memory devies, etc.) enabled. Though the compiler can strip out all unused functions when compiling your final application, some functions are called from within the library when certain features are enabled at compile-time of the library.

E.g. even if you don't use the window manager in your application, it will link a number of WM functions when calling GUI_Init.

Regards,
Wouter
