7i76e with 7i75

Is there anything special required to add a 7i75 card to a 7i76e? I looked on Mesanet.com, but didn't find any firmware to download for this combination?

Running Linuxcnc 2.8

 

No, just plug and go.
It is a break out board with good protection for the FPGA.

Thanks for the quick reply TommyLight, I have it plugged in to P1, the led is lit on it, and I have 5v on the ground and supply pins. I ran halcmd, with the board attached and detached, and didn’t see any change in the available number of inputs. Any ideas why?

In hal you use the normal GPIO pins, 7i75 should be transparent to FPGA.
What does mesaflash readhmid return ?

I’ll have to check into mesaflash readhmid tomorrow morning, not sure if I have that installed on the computer. Thanks again for your help.

If you install a recent version of mesaflash:

github.com/LinuxCNC/mesaflash

( build/install instructions on bottom of page )

You can get the GPIO -- 7I75 pinout:

mesaflash --device 7i76e --addr [card_ip_address] --dbname2 7i75 --readhmid
 

I did have a version of mesaflash installed, but was unable to connect to the 7i75 board, the terminal didn’t like the —addr part, probably too old of a version of mesaflash, and my computer isn’t easily connected to the internet. But I was able to read the 7i76e board, which showed me the P1 and P2 pin addresses, which finally allowed me to figure out which gpio pins I was looking for, and I was able to locate them in halshow. On to the next challenge, thanks again everyone!
