Lattice_November2014_pg8aLogo_Lattice
Embedded HMI on Chip (HOC) is a compact Human Machine Interface (HMI) solution for rapid creation and implementation of embedded graphical HMIs on Lattice FPGAs.

The HMI on Chip solution has been developed by Mikroprojekt on the LatticeECP3TM 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.
