Pin Usage on 7i76e Board

I think you would need the following firmware to give three separate encoders:

7i76e_7i76x1_Dpl.bit

You also need the firmware with "pl" in the name.

I'm sorry but I don't understand

/EDIT I see you have two thcad's, so I deleted my post which assumed you had one thcad.

The thcad for ohmic sensing connects to encB. But as philC said, you need the firmware for it.

Help please, I am trying to update the firmware and I get this error.

The most direct way to update the firmware would be to use mesaflash directly:

mesaflash --device 7i76e --addr 10.10.10.10 --write 7i76e_7i76x1_Dpl.bit

If the 7I76E is set for the 10.10.10.10 IP address or

mesaflash --device 7i76e --write 7i76e_7i76x1_Dpl.bit

If the 7I76E is set for the 192.168.1.121 IP address

followed by power cycling the 7I76E or running this command:

mesaflash --device 7i76e --addr 10.10.10.10 --reload

If the 7I76E is set for the 10.10.10.10 IP address or

or

mesaflash --device 7i76e --reload

If the 7I76E is set for the 192.168.1.121 IP address

Good morning, I do what you say and I get this error. I don't know what to do anymore, can you help me? Thanks

Run that in the same directory as your bit file or make sure you use the correct filename.

You need to fetch the 7i76e.zip support archive from mesa, unzip it,
and run the mesaflash command in the directory with 7i76e_7i76x1_Dpl.bit
(in the archives configs/hostmot2 subdirectory)

I have already updated the board but I still do not know what output I give to the Thcad-10 for height control and Thcad-5 for ohm sensor. Thanks

For Arc Voltage select the encoder as shown in the attachment.

There is no ohmic in PnCconf as yet, it needs to be done manually. Usually encoder 1.
