CycloneIII Dev-Board Graphical and Character LCD

Hi,

I'm using the Bitec CycloneIII Dev. Board with a character LCD and second graphical LCD.

Both are using common signals (except of CS). I can use either the character or the graphical LCD. How can I use both. The character is used via the HAL-interface and the graphical is used with a tristate bridge and the bitecs-IP for this Display.

What must I do for both displays working together?

Best regards

Mark
