Hi,

I am using emWin library for Graphic interface. Currently I have designed a screen with an image, 8 Icons and few numbers on the screen. I have a processor with 256KBytes of memory. When I compile the code, I see that my code occupies 90% of the program memory. I have checked the resource usage and the icons with screen should not be taking up so much memory. I commented the screen with just GUI_Init() and GUI_Delay() in the code and it occupies 16% of the memory.

1. Can someone explain what could be taking up so much memory space and how it can be reduced?
2. Will I need an external flash while using emWin to design more than two screens?
3. Is there a way to make use of just the code that's being used/ have I setup something wrong on emWin that could be causing this?

Appreciate all the help!

Best regards,
BMD

Sure. Please see attached.

Hi Sven,

Just trying to see if you were able to work on those files. Did you find something on those files that would help us reduce the memory consumption?

Thank you for your response.
I thought the same, that images could cause this memory issue. But when I took out the images and all the I had in the code was just GUI_Init() and GUI_Delay(), the memory consumption was 16% i.e 47 KB of ROM. Is this how much it usually takes or does this seem unusual?

Actually you don't really need an eval board. You could just reproduce it on PSoC creator software to see how much ROM is being used during compile.

Can anybody confirm this for me please?

Thank you,

Florian,

Thank you so much for confirming that for me.
