    Attila,

    Can this LCD be used in landscape mode?
    ie rotate fonts etc.

    Regards Gavin

      Not easily. Its natural format is portrait. However you can make up custom landscape fonts with the aid of the user bitmap commands.

        How much significant difference is there between this (uLCD-320-PMD2) and the µOLED128-GMD1 besides resolution and OLED technology vs LCD technology?

        Parallax (United States) only sells the µOLED128-GMD1 but I like the higher resolution of the uLCD-320-PMD2. Are there any other significant advantages of the uLCD-320-PMD2 over the µOLED128-GMD1 before I make my decision to purchase either one? I see that Little PCB Solutions (United States) sells both of them. I will be using the Parallax Basic Stamp II or an SX-28 micro-controller with one of them.

        Let me know...

        Thanks!

          Hi,

          There is really not much differences if you take out the resolution of the screen and the technology.
          The µLCD 320 PMD2 has some more functions than the µOLED 128 GMD1 such as draw ellipse, but that's likely to be improved via firmware upgrade.
          The µLCD 320 PMD2 also supports trackball input if I remember correctly.
          And there are slight differences between the processors (Picaso / Goldelox) when playing movies;
          I'd say the Picaso is globally better but that's my opinion

            Thanks for the info!

            I posted in another forum and was told the following:

            1. Expanded User Bitmapped Character support: 8x8 (64 characters), 16x16 (16) and 32x32 (8). The uOLED modules currently support only 8x8.

            2. An Ellips drawing command

            3. A floating pointer (think floating "cursor")

            See the documentation at: http://www.4dsystems.com.au/downloads/micro-LCD/uLCD-320-PMD2/Docs/
            The uOLED displays are brighter and higher contrast, but the uLCD-320-PMD2 is one of the brightest LCD displays available.

            I saw a YouTube video that used this and a Cannon micro-trackball. Can you actually connect a mouse / trackball input to this with commands to support this (e.g. select an icon and DO SOMETHING?). That would be neat.

              The PICASO chip is a DSP based engine runing at 50 MIPS and the GOLDELOX is a RISC platform running at 12 MIPS. When 4DGL platform is released, the user application software written in 4DGL will run much faster on the PICASO.

              Although the OLED technology is very good the TFT LCD used in the uLCD-320 is extra special. It employs a special "Black Pixel Mask" which you won't find in many LCD's and this enhances the contrast ratio to an incredible 10,000:1 compared to the OLED which is 1,000:1. You really have to see the uLCD-320 in action to appreciate the viewing quality.

              Hope this helps in making up your mind.

                Wow. That's incredible. I think I already have. Can you answer how it supports trackballs as in the YouTube video I saw on this? Can you actually click on an icon graphic and it DOES SOMETHING? If that is the case then I am sold.

                Thanks for the great information.
