K70 Graphical LCD controller support

danif — Wed, 24 Apr 2013 17:10:43 GMT

It is mentioned in the specification of K70 controller that it has Graphical LCD controller for 800x600 pixel resolution LCD. I have three questions.

1 - How to run a graphical LCD with more than 800x600 resolution.

2 - Can K70 enter into low power modes while Graphical LCD keeps on displaying without any disturbance.

3 - Can a graphical LCD controller be used to run a segmented LCD..if yes how?

Thanks,

Dani

1.- You can interface the LCDC module with larger displays however the controller will only send a 800x600 image, leaving the rest of the display inactive.

2.- As you can see in the following table extracted from the Reference manual, the LCDC module retains full functionality in VLPR and VLPW

3.- I'm afraid the K70 LCDC module can only interface with graphic displays, however you can use any of the GPIO ports to achieve segment LCD communication.
