mesa 7i76e (7i76e_7i77x2)

Hi all!

I really need a firmware for mesa 7i76e for 2x7i77 (7i76e_2x7i77).
Best Regards Vitaliy.

I apologize for hijacking this thread, but my issue is very similar to yours. I need the firmware for the 7i76e with a single 7i76. I downloaded the zip file containing the firmware from the mesanet.com website (mesanet.com/software/parallel/7i76e.zip), but there are several .bit files and I cannot determine which is right for my application.

The naming scheme is somewhat non-intuitive, these are the closest I've found:

7i76e_7i76x1D.bit
7i76e_7i76x3D.bit
7i76e_7i76x1pD.bit
7i76e_7i76x1_Dpl.bit

Additionally, how do you go about flashing the firmware to the mesa card?

Thanks,

Edited, see below
How to use mesaflash is detailed on page 33 of the 7i76E users manual that can be downloaded from the mesanet.com website, here:
store.mesanet.com/index.php?route=produc...oduct&product_id=290
The "specifications" tab.

7I76e_7i76x1_7i77x2d.bit

If you want to add one (or two) 7I76's, 7i76e_7i76x3D.bit
would be the one

Thanks for your help, it would have probably taken me quite a bit of trial and error to figure out which firmware to use.

I have now flashed the 7i76e_7i76x3D.bit and it shows “number of IO Ports: 3”, and also includes three sections labeled as follows:
“IO Connections for on-card” which has step generators 0-4
“IO Connections for P1” which has step generators 5-9
“IO Connections for P2” which has step generators 10-14

Now my question is how to get LinuxCNC to be able to use the I/O from the 7i76. I'm certain someone must have asked this before, but my search has come up empty. Is it as simple as just using a different prefix for the pin names or will I need to put something else in the .hal or .ini file?

I've already tried running Pncconf again and it does not show the additional I/O or give me an option for adding the 7i76, so I assume I've now reached the end of its usefulness.

Thanks,
