Fitting an encoder on a Tormach 1100

freeby.mesanet.com/5i25_t2_7i85s.bit

Many thanks for your time Peter I will have ago and flash the board.

Ok update The 7i85s board has arrived and flashed with freeby.mesanet.com/5i25_t2_7i85s.bit.

I have stopped PP from re flashing successfully.

I have the 5i25 in a spare PC using P2 (26 pin header) to connect to the 7i85s jumper-ed for PC power ( there is one led lit on the board)

Should I now see the encoder pins on the 7i85s or not. what should they look like?

They will show up as belonging to the 5i25.

If you start LinuxCNC from the command line you should get a listing of the physical pin locations.

And you should see the associated output pins in HAL.

Ok It appear to have them:-

Could you give me some pointers of what I need to do to be able to use them ie use a custom hal file so as not to interfere with PP
Do I have to tell hal how many encoders etc. I am a bit lost now. Tnx.

That looks like either the wrong bitfile or your "num_encoders" in the "loadrt hm2_pci" needs to be changed.
