The µOLED-320XX-P1 series are compact & cost effective all in one display modules using the latest state of the art Active Matrix OLED (AMOLED) technology with an embedded PICASO graphics controller that delivers stand-alone functionality to any project. The easy to learn and use 4D Graphics Language (4DGL) with its vast built in library functions will allow rapid application development.

4DGL is a graphics oriented language, allowing the developer to write applications in a high level language (syntax similar to popular languages such as BASIC, C, Pascal, etc.) and run it directly on the PICASO processor embedded in the µOLED-320XX-P1 modules.

4DGL allows the user to take complete control of all available resources on that hardware platform such as the Serial Port, Graphics AMOLED Display, uSD-Card, I/O pins, etc. This eliminates the need for an external host controller/processor to drive the µOLED-320XX-P1 modules via serial commands. It provides the user complete control over the hardware module allowing them to quickly develop powerful applications.

Customer Comments

  • The most disappointing thing about this module is that the 4DGL language doesn’t support a float type. This makes anything but the most simple math functions impossible. Given how much this unit costs, I thought it would be able to do just about anything.
    Also, it advertises TTL I/O channels, I2C, UART, etc, but the “expansion” connectors on the back are difficult to find.
    The 4DGL code is also a bit strange sometimes. Some of the functions have poorly defined inputs and either bad or nonexistent sample code.
    Overall it is a nice little display, and it does have a lot of convinient functions built in (like printing text to the screen, or displaying pictures/buttons). If all you want is a simple display with some basic processing power then this is perfect, but I’m finding that interfacing it with other components is becoming a bit of a pain.
    Another note: Although it says it in the description, this only takes uSD cards 2GB or under. Anything over that is not supported and will not work.

  • We wrote a little article about these 4Dsystem’s OLEDs and how to use them in your own project a while back:

  • Has anyone gotten the audio functionality on this board to work? We are trying to drive the speaker at full volume, and are not getting anything out of it.
