SSI absolute encoders and analog servos

Hi,

Ok. Could you give me simple example manual configuration?


Tero

Start by setting up something vaguely close, just to get the file structure, and work from there.

Hi,

I tried to use 5i25 with 7174 but it does not seem to work. Also was unable to find SSI configuration with Mesa cards. Not to mention that 7i83 is not in Pncconf serial daughter card list. So it is hard to make a config with Pncconf that is even close to what I am looking for.

Actually, rather than adding a layer of complexity (guessing how to get anything out of pncconf) it's probably easier to pick
configs->by interface->mesa->hm2-servo->5i20. That will copy the config into your LinuxCNC directory.

The go thorough the INI changing things (like board name) to suit your machine. (change the board to 5i25 and CONFIG to "")

Then you need to go through the HAL changing things to suit the actual pin names in your config.

You can get the list of mesa-card pins once the hardware is connected and powered by opening a terminal and

Ok. Thank you for advice. I should receive needed cards in few weeks. After that I can start configuring.

Hi,

I flashed card with mesaflash. And did the best I could with config files. Now I see following with show pins :

But these pins are there even if 7i44 or its daughtercards are unconnected. How can I see actual pins for daughtercards I connect?(2 7i71's are connected via 7i44 but no more pins are listed)
