Rutronik offers Pixxi-44 series for colour HMI 

Many applications developed and written for 4D Systems display modules with Smart 4D Systems’ Picaso or Diablo16 graphics processors can also be run on the Pixxi-44 series of display modules. It is available from Rutronik and is, said the distributor, the best alternative for anyone looking for display modules that run with the currently unavailable Diablo16 graphics processor.

The intelligent display modules are part of 4D Systems’ gen4 range which includes TFT-LCD colour displays with non-touch (P4), resistive touch (P4T) or capacitive touch (P4CT).

The displays feature microSD memory, optional SPI flash memory, general purpose I/O (GPIO) and communication, and integrated audio generation.

The integrated 4D Labs Pixxi-44 graphics processor has 14 customisable GPIOs suitable for digital I/O with 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.

The gen4 modules are designed to be easy to integrate and use and also designed for installation where space is limited. This minimises the potential impact of display-related circuitry, said Rutronik. 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 compatible with the Workshop4 IDE (integrated development environment) and its four different development environments, providing users with the tools and options necessary to program and manipulate the display in the desired function for the system project. 

The range of intelligent display modules is available in a choice of sizes – the 4.3, five- and seven-inch models with 480 x 272, 800 x 480 and 800 x 480 resolution, respectively.

They also have 32kbyte flash memory for user application code and data and 30kbyte SRAM. The TFT LCD modules are equipped with a five-pin 2.54mm (0.1-inch) header for programming or host interfacing  and a latch-type micro-SD memory card connector for multimedia storage and data logging.

Selectable 32Mbyte serial flash memory is provided for multimedia storage, data files, fonts or for storing additional code functions (mutually exclusive with micro-SD usage). There is also a DOS-compatible file access (FAT16 format) as well as low-level access to the card memory.

Four mounting tabs with 4.0 mm holes are provided for mechanical mounting with M4 screws (P4/P4T/P4CT models only) 

The PCB is classified as flammable according to UL 94V-0.
