Hi 

It is my first time I want to work with lpc1788 and lcd(driver is  NV3035C).

Does emwin support this LCD driver?

also can I use emwin for lpc1788 if I don't have external sdram? I just want to show a simple character on LCD for phase1.

Hi Ati Haj,

   1. Does emwin support this LCD driver (driver is  NV3035C).?

   I have checked the Segger emwin Display drivers, but I didn't find your driver.

  You also can check it from this website:

Display Drivers | SEGGER - The Embedded Experts 

   2. Can I use emwin for lpc1788 if I don't have external sdram? 

  Yes, you can use the emwin without the external sdram.

You can refer to the MCB1700 emwin BSP:

Wish it helps you!

Have a great day,
Kerry

Hi Kerry

Thanks so much for your help,

Actually NV3035C in the controller on LCD side, lpc1788 has it's own lcd controller. The question is, which controller emwin works with?

I have another question : lcd I am using is 24bit, with TWI interface, with this condition still emwin works for that without sdram?

  Please check the link which I give you before, you can find it from segger website.

  2.  lcd I am using is 24bit, with TWI interface, with this condition still emwin works for that without sdram?

  All the bits and controllers can be found from the above link, please check the according controller on LCD side.

But I didn't find NV3035C in the list.

Have a great day,

Thanks Kerry,

You are right , NV3035C is not supported, but what I found is I can use emwin display library for lpc1788 has on-board lcd driver.

The other question I have and couldn't find any answer is : the lcd I am using is 24bit with I2C interface. how can I modify the library to work with the LCD I have?

Hi Ati,

If you are using the I2C interface, I think your LCD already have a higher level controller, you can refer to your LCD documents, just send the according command with the I2C bus.

You can find some typical usage and code for your LCD, normally the LCD company will provide the according information. Then you can add it to the LPC project.

Have a great day,
Kerry
