TWR-K65F180M with TWR-LCD or TWR-LCD-RGB, on MQX

[acampbell]

Hey all!

I have a TWR-K65F180M running MQX, and I would like to try putting an app on it with a GUI. Obviously I need the graphics hardware; I understand the TWR-LCD module is compatible with the TWR-K65, and I would assume the TWR-LCD-RGB module is as well.

So is it reasonable for me to try to set up a GUI project on the K65 board? Is it true that the LCD modules will work?

I also see that Freescale offers the eGUI kit, which appears to come with the graphics drivers, but the only example project included is for a TWR-K70 board. However the PEG Lite software seems to be more closely linked with MQX. Any word on which of these would be better and/or easier on the developer?

Hello Aaron,

Like Yoram mentioned, unfortunately the K65 doesn't contain the graphic LCD Controller module like the K70.

For the K70, please check the below application note and let me know if this helps!!

In addition please check the below thread

TWR-K70F120M + TWR-LCD-RGB using CodeWarrior + eGUI code example

Have a great day,
Sol

Hi Aaron,

To the best of my understanding, the TWR-LCD-RGB requires LCD controller on the MCU and thus is used with the K70.

K65 does not have an LCD controller and thus can work the graphics using SPI or parallel only, hence uses the TWR-LCD.

Saying that, I'm also looking for an MQX+D4D demo I can use - did you find any?

I did not; for my app, I ended up using FreeRTOS on an ST Micro board with emWin instead.
