Subject: Re: [Emc-users] Looking for 7i92 bit file
Correct. It's not an issue. Just noted it. I looked at the source and
it does not assign a stepgen to the 16/17 pins of port 2. I might
want to change that for the next conversion where the Z axis will be
used.
Did you setup the slave axis as X2?
It does but it deliberately sets it to stepgen 8 so it can be disabled
if use for spinel control on a 5ABOB breakout
I did set it up as X2. The INI and HAL also show that but I dont
get signal at the pin. I checked with the scope.
Probably a hal issue, I would check the hal file stepgen connections
I checked the hal, it's automagically generated. Not much I can screw
up there. It looks like it is not getting command or the pins are not
assigned
If thats the case, that is most likely a hal error. I would trace
the X2 position command with halshow.
I suspect that you are right. For the sake of time running out I just
slaved the X stepgen in the bit file. I am using a simple trivkins with
no slave axis defined. The only issue now is that the DIR signal on the
slave has to be inverted somehow. Is there a way to NOT the pin in the
bit definition?
