By delivering a universal standard for display type add-on boards, both development time and money are saved, and enormous design flexibility and scalability made possible.
Commenting Nebojsa Matic, CEO of MIKROE, said, “With DISCON, we are ensuring absolute compatibility between the development board and any of the supported displays, regardless of their size and type.”
The DISCON standard specifies functional and aesthetic requirements that must be respected in the development process.
These specifications include the physical layout of the display board, communication and power supply pins, the size and the shape of the display board, and the silkscreen marking conventions for both the add-on boards and sockets.
It permits all sizes and styles of TFT display to be used – currently 3.5in, 4.3in, 5in and 7in units, and capacitive, capacitive with bezel, capacitive with frame, and resistive styles are supported.
The DISCON display board socket consists of a 2x20-pin connector with a proprietary pin configuration and silkscreen markings. The connector is a female 2x20-pin device, on a standard 2.54mm pitch. It may also have a polarisation post for easier positioning of the display board. The pin-out consists of four different groups of pins – I2C, GPIO, data pins for the parallel data-port, and optional control pins - along with power supply pins.
