Hello every one.

I am new to EMC2 and i can not find any file named hal_parport.c or MAX_PORTS ( to define number of ports).
I have read that i can control 8 parallelports.
Can i configure those 8 ports in "stepconf" wizard ?
How do i get those ports upp and running ?:confused:

Hello every one.

I am almost positive that the answer to the above question is no. Stepconfig is limited to assignments for one parport. You could use it as a starting point for the first port. What kind of machine are you thinking of that will require eight parallel ports?

How do i get those ports up and running ?:confused:You will have to write (or modify) you own ".hal" file that will assign the pins and ports and it will need to contain a line like this that assigns all the port addresses and whether they are assigned non-default input or output functions:
loadrt hal_parport cfg="0x278 0x378 in 0x20A0 out"

Read the documentation on HAL and PARPORT in EMC_USER_MANUAL.pdf in particular chapters 6, 7, and 8.

Thank you for good answers Alan.:)

I will only be using 2 or 3 ports for HALUI on a lathe.

If i understand you right, i dont have to define MAX_PORTS in
hal_parport.c mentioned in the documents ?

KRUMMINo, you don't have to change the source code, unless you need more than the 8 ports allowed by default. :)

The code as it is allows you to use from 0 to 8 ports.

OK now i get it.:idea:

Of course, thats the source code.
Now the clouds are not as thick in my head.

Thank you Steve :)
