Hi, I have running the display very successfuly using the serial interface, a MEGA Aduino and your sample code. I am now trying to get it switch to 8080 parallel mode and having difficulty.  In the application note, the signals CPU and PS are tied to GND and 3.3V respectively, but in the sample code toggles these lines in the case of 8080 parallel.

Can you tie these as shown in the app note and comment out the logic for the CPU and PS in the code?

Thanks!

  Those pins are used to select the interface you would like to use.  They can be either fixed (tied to VDD/GND accordingly) or connected to GPIO and toggled appropriately in software.
