Looking for LCD sample software

I'm using the Hitex EVA1850 with LPC1857 chip.  Looking for sample code that sets up the LCD controller and supports 18 or 24 bit TFT display.  I see emWin mentioned, but it looks like way overkill.  There's also swim, but all links here to swim go nowhere.  Any good sample available for this processor and LPCXpresso?

Thanks

Up to now we didn't implement examples for 18-bit or 24-bit TFTs. We always used 16-bit colors.

The first reason is that on the standard display modules we use for our eval platforms the displays are hardwired for 16 bits.
The second reason is that using 18 bits instead of 16 bits means that you need to handle 32-bit values (16 + 2 bits, the rest is thrown away).
This is a bigger effort on the software side, especially when you work with graphics libraries.

Also these relatively cheap TFTs will not show a big difference in quality when working with 18 bits instead of 16 bits.

There is another thread where you can get code for a 24-bit TFT:

Ahh, I thought that was for the little on-board 128x32 SPI LCD.  I'll give that a try.  Thanks.

Hi MX21,

Have you looked at our LPCOpen software platform? There is an LCD software example called "periph_lcd", among several other software examples in our three supported IDEs: Keil MDK, IAR EWARM, and of course our own LPCXpresso.
