Dear NXP, dear friends,

I am using LPC4078 with no graphic controller to control a LCD via 16bit parallel interface. Now I want to use emWin library but I can not find any example of emWin for LPC4078. May I ask:
1. Does emWin support LPC4078? Are there any free, prebuilt packet for LPC4078?
2. If no packet available for LPC4078, are there any way to custom emWin LCD driver to work with LPC4078 via 16 bit parallel interface

Thanks you very much for your help,

Hi phouckal,
You can use LPC1788 BSP as starting example. Please see BSP at below location.
https://www.lpcware.com/content/project/emwin-graphics-library

Also look into

and

Please see below the answers/comments.

Yes. You can use emWin M4F library from emWin page and LPC1788 BSP example can be used as a starting point.

I don't think we have 16-bit interface example without using LCD controller. If you want to use RGB interface, I will recommend to use LPC4088.

Dear mc,

Thank you very much for your information.

I am currently use LPC4078 with LCD 16 bit, no RGB support.
Is that my system can not run NXP emWin, is that right?
If I want to use NXP emWin, I must switch to LPC4088 (or other MCU has LCD controller) and change the LCD to RGB support. Is that right?

Thank you very much for your help

Hi phuockal,
You can run NXP emWin on LPC4078. How are you planning to use 16-bit interface as LPC4078 does not have LCD controller?
EMC?

Hi MC,

LPC4078 does not delicate any port pin for LCD control signal. so I just connect a GPIO port to control LCD. Please see the attached file.

My situation is: I already make hardware and the LPC4078 can control the 16bit LCD well without any problem. For now I want the LCD display more complicated thing and I recognize that using emWin is the fastest solution. Even try, I can not find how to make the emWin run on my hardware.

Best regards

Hi MC,

Does emWin support for the RDB4078: http://www.nxp.com/board/OM13038.html#showall

Thanks

Afaik, there is no example driver for the RDB4078.. but emWin will work with ANY board - you will have to write the display controller driver ( which is quite a simple job).

Hello,

yes, just custom the lcd driver. I am done and I can share my work for any member.
