STemWin writing to display buffer with interrupts disabled

Question asked by hauser.philipp on Feb 20, 2015
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!
