STM32F103VG FSMC/LCD

Question asked by sorio.andrea on Dec 17, 2013
Dear Sirs

I developed a system with a STM32F103VG  processor.
The processor is connected to an LCD with Intel 8080 interface.
I use FSMC to configure and manage the LCD.
The processor is configured to run at 72MHz.
The DMA operation to the LCD isn't fast as I aspected.
A write cycle is 4us long! I'm not able to reduce this time.
I changed the AHB clock prescaler to reduce the FSMCCLK to 36Mhz. In this way the write cycle is 8us long!!
I don't understand where is the mistake.

Could you be so kind as to help me?!

Thank you in advance

Best Regards

Andrea Sorio
