Best interface to drive LCD display

jeffdev — Tue, 24 Feb 2015 00:14:38 GMT

I would like to drive the following display:

It uses 6-bit RGB interface. Can someone recommend the best interface on the K22 to do this? I do not want to do bit-bang or require software handling after every pixel/line. I would like to have the entire screen data in an array and have the hardware handle the entire transfer. I assume Flexbus should be used but I'm not sure how to setup it up without using the address bus. Thanks for any info.

Hi Jeff,

What you try to do is not possible using Flexbus because you need the address bus. You may need a LCD controller module. Our Kinetis K70 devices provide LCD controller. PLease see below.

Best regards,

Carlos

Thanks for the info. I was hoping there would be some workaround to get Flexbus to work. I will look at the K70.
