HOC : Embedded HMI-on-Chip Solution

Embedded HMI on Chip (HOC) is a compact HMI solution for rapid creation and implementation of embedded graphical human-machine interfaces (HMIs) on Lattice FPGA’s. The HMI on Chip solution has been developed by Mikroprojekt on the LatticeECP3™ HMI Development Kit.

The solution offers the complete functionality required for display driving, graphics rendering and embedded visualization, scalable from small size QVGA to large full HD displays, as well as a wide variety of touch screen and system interfaces.

The advantage of HOC solution is the concept of HMI-on-chip: TFT display driving, graphics rendering, touch screen handling and system interfacing are handled directly in the FPGA hardware, without the requirement of an operating system and associated design complexity required by the typical graphical solutions.

The built-in graphical engine (IQ-Engine) interprets an integrated interface project file to visualize and modify a set of values shared with the host application, allowing easy integration of the user interface. Using an FPGA brings an absolute flexibility of the solution to the user, supporting the widest possible range of displays, memories or system interfaces.

The HOC solution can be evaluated on the LatticeECP3™ HMI Development Kit. The LatticeECP3™ HMI Development Kit couples the LatticeECP3 Versa Development kit with an add-on HMI display kit. The HMI display kit is based on a 4.3’’ TFT touch screen display mezzanine module for the LatticeECP3 Versa Kit. The add-on display mezzanine module also provides an SD card slot allowing for easy deployment and evaluation of graphical user interfaces.
