You can see from the pin/parameter lists that all encoder/pwmgens/stepgens are enabled
This is what happens with a missing config="blah blah blah" token
Likely this is a quoting issue
DRIVER_PARAMS="board_ip=10.10.10.10 config=num_encoders=1 num_pwmgens=1 num_stepgens=5 "
probably should be
DRIVER_PARAMS=board_ip=10.10.10.10 config="num_encoders=1 num_pwmgens=1 num_stepgens=5 "

He mentioned somewhere earlier that he has that line in the ini file, not in the hal file where it should be.
Or was that a different thread ?

In that particular setup the driver configuration parameters are in the ini file
Actually I think this is a better way to do things as it means that the same hal file can work with
different cards/machines and as much as possible of the card/machine specific info is restricted to the ini file

Thank you so much Peter, I could not see the wood for the trees. It was the " in the wrong place as you noted.

Peter.
All the i/o pins on P1 now give me 5v apart from pin I 019 HDR pin 3 which reads zero. I might have killed it putting 5V onto it
I now have 3 mpg wheels and 3 sets of limits all working fine on P1 now. I could live without the I 019 if it is broke.
Thanks

Putting 5V on a I/O pin _might_ kill it if it was enabled as an output (and low) but this is unlikely. As inputs, the 5I25 pins will accept -0.5V to +7V so a 5V input is fine.
Note that it's easy to exceed the -0.5V limit if you accidentally short the I/O pins to a machine frame, as frame grounds often have HF noise potentials of several volts and basically unlimited current. This will quickly destroy the input protection diodes on the bus switches/FPGAs (which have a 50 mA maximum current limit)

Thanks the the explanation. This is just on the bench at the moment so not connected to a machine.
I think it was configured as an output. I have more than enough pins to do what I want so no prob.
