Yes, Mesa has been kind enough to open-source all the vhdl for their cards. I learned vhdl from reading Peter's excellent logic. You can look all the documentation up on Mesa's site and in the LinuxCNC source tree. You have to install the Xilinx webpack, but you don't have to use the Xilinx gui if you don't want to, as the LinuxCNC/Mesa setup has makefiles for compiling the bitfiles. I have successfully customized Mesa's logic for the 7i43 for specific needs, and I have used what I learned from their vhdl functions to create logic for both Digilent fpga boards and our own custom hardware. The Machinekit fork of LinuxCNC has the fpga logic running on ARM/FPGA boards.
Mesa has made a tremendous contribution to the community with their hardware and firmware. -- Ralph ________________________________________ From: Chris Albertson [albertson.ch...@gmail.com] Sent: Wednesday, September 7, 2016 9:47 AM To: Enhanced Machine Controller (EMC) Subject: Re: [Emc-users] Need unlocked copy of a pdf for a breakout board I just bought two of. I have not yet bought a 5i25 card. So my question might be answered in whatever documentation comes with it. Can this card be used as a general purpose FPGA development card? Is the process well documented some place? If so then this card can be used for almost any purpose, for example I could build a function generator a logic analyzer. The other question: So we get the source code VHDL files for the firmware inside this card? This means we could use any FPGA card or even build one from a FPGA chip On Wed, Sep 7, 2016 at 6:32 AM, Ralph Stirling < ralph.stirl...@wallawalla.edu> wrote: > The 5i25 is completely flexible, ......
