CNC 的开放码,EMC2 V2.2.8版

This directory contains the source code and binaries for the HostMot2
firmware, for Mesa Electronics' Anything-IO cards.  (Additional FPGA
firmware and example host-side source code is available from Mesa
Electronics.)


The "src/" directory contains the new, unified VHDL source code.
The board directories ("5i20/", "7i43/", etc) contain the pre-compiled
firmware binaries and the old deprecated VHDL source code.
