Out of Memory with 800 x 480 display using Glide

I have a 5" 800x480 display that I seem to get out of memory with just a simple app that creates a window.

I am running Glide with a ChipworkX module.

THis is the output from the GC prior to calling the GlideLoader.LoadWindow() function

From what I can see, there is ample free memory available. Some 58MB.

I am assuming the BITMAP would be 800x480x16 which is around 6MB.

The way I plan to code this, only 1 window would be active at any one time and in memory. The previous one is disposed of prior to the new one being created. This has worked well in a previous app with the 4.3" LCD and multiple windows.

How does the G120 work with the CP7 panel, which has the same resolution? It has far less memory than the ChipworkX.

You need ot increase the custom heap size. http://www.ghielectronics.com/docs/58/custom-heap-large-objects

What a productive night.

Thanks for the help Gus.

Now to get the capacitive touch to work! :slight_smile:
