Catch up on processor supply bottleneck: smart 4D systems display modules

With the Pixxi-44 series, Rutronik claim that 4D Systems offer the best possible alternative for all those who are looking for display modules that run with the currently unavailable Diablo16 graphics processor.

Thanks to the Pixxi-44 intelligent display modules, the gen4 range from 4D Systems includes various TFT-LCD colour displays with non-touch (P4), resistive touch (P4T) or capacitive touch (P4CT). These feature microSD memory, optional SPI flash memory, GPIO and communication, and integrated audio generation. Therefore, they are ideally suited for quick and easy integration of a full-colour HMI into almost any application in a variety of vertical markets, such as mobile ventilators.

Special highlight: Many applications developed and written for other 4D Systems display modules with Picaso or Diablo16 graphics processors can also be run on this intelligent gen4 display module – depending on the Picaso or Diablo16 functions used in each case.

The integrated 4D Labs Pixxi-44 graphics processor offers a wide range of functions and options for flexible design and custom applications. The processor has 14 customisable GPIOs suitable for digital inputs/outputs – four specifically for analogue inputs, two each for I2C and UART interfaces, respectively.

The SA display's 30-pin ZIF/FFC/FPC socket allows connection via 30-pin FFC cable to an application, motherboard or accessory boards for additional functional expansion.

Space-saving, simple integration

During the development of the gen4 module series, particular attention was paid to simple integration and use, considering space requirements. This minimises the potential impact of display-related circuitry. For example, the display-related electronics are located in the plastic mounting base, which allows application boards to be mounted flush on the back of the gen4. The advantage is that the surface of the application board thus remains free for user circuitry.

The gen4 family products are all fully compatible with the Workshop4 IDE and its four different development environments, providing users with the tools and options necessary to programme and manipulate the display in the desired function for the system project.
