STemWin writing to display buffer with interrupts disabled

Hi there,

I'm using STemWin for writing data to the display buffer located in an external video ram. Unfortunately reading / writing to this vram works only when the interrupts are disabled.

Does emwin provide a way to adapt the routines of reading / writing to the display buffer?

Something like:

writeToDisplayBuffer(a,b)

{

   disableInterrupts

   write data a to address b

   enableInterrupts

}

Thanks for your help!
