Hello friends

How can Getting rid of GLCD Latch delay ?

Things I've done so far :
If changes are made in lines update my GLCD (Only in case of change)
However, the speed of the Program has a bad effect.

If there are better methods
Please guide me

STM32F407 144Mhz
KS0108 64*128
 

KS0108 is super slow itself. Connecting to ARM may have a sense if you will use it with DMA, than you do not have to wait while the latch will trigger the data. Or use RTOS and keep all lcd function inside dedicated routine. But anyway, this display is a poor solution from perfomance point of view.
 
thank you
Is ST7920 faster?
