4D Systems 70DT Intelligent Display Modules and Kits

4D Systems 70DT intelligent display modules are designed for applications demanding a large intelligent display module. Driving the display and peripherals is the DIABLO16 processor, a very capable and powerful chip that enables stand-alone functionality, programmed using the 4D Systems Workshop 4 IDE Software. The Workshop IDE enables graphic solutions to be constructed rapidly and with ease due to its design being solely for 4D's graphics processors. The DIABLO16 Processor offers considerable FLASH and RAM upgrades over the PICASO processor, and also provides mappable functions such as I²C, SPI, Serial, PWM, Pulse Out, and Quadrature Input, to various GPIO, and also provide up to 4 Analog Input channels.

The display module has an array of features including PWM for sound, Touch Detection, micro- SD memory storage, general-purpose I/O including Analog Inputs, multiple TTL Serial, I²C and SPI channels, and multiple millisecond resolution timers, amongst many more features. Anything that has been designed in the past to run on a PICASO Processor can theoretically run on this DIABLO16 Module with minor changes. The uLCD-70DT also features 2mm pitch male headers to connect an optional module. 4D Systems intends to bring out one or more modules that will be compatible with the uLCD-70DT, offering connectivity such as WiFi or Bluetooth.
