LCD 8-bit bus/RGB565 support

jonver — Wed, 24 Aug 2016 14:06:52 GMT

Hello,

I wonder if an LCD with an 8-bit bus and RGB565 color space is supported in any i.MX product (preferably i.MX6UL).

A pixel is represented by an 16-bit number on the 8-bit bus, so 2 clocks are needed to drive 1 pixel. An example of such LCD is ili9335.

If this is supported:

1) how do I wire this

2) how do I load the driver

I'm using Yocto as operating system and have the DART-6UL demo board.

Thanks!

Jonathan

Hi Jonathan

seems i80 ili9335 could be supported by i.MX6UL according to

Table 32-3. Pin use in MPU Mode and VSYNC Mode i.MX6UL Reference Manual
