Need help configuring a 5i25 with Gecko G540

Hi,

I just installed a Mesa 5i25 card, flashed it for the G540, and commenced configuring PNCConfig, I have got some way in that I can test drive the stepper motors OK, If I leave out any homing I can go to the axis program and also drive the steppers back and forth.

However I am stuck on configuring the limit/home switches, in stepconf I had them set on pin 10 minimum limit + home X, pin 11 for Y and 12 for Z, I am trying to emulate these settings without any luck on I/O 3. I think I have the search direction and velocities correct (maybe not) but when I run it I cannot turn power on because I get Joint 2 limit errors.

Also I have no idea how to get my router to be controlled via pin 14 at 0-5v and 50Hz as the G540 requires.

I'm not sure what info I should provide to assist so some hand holding and guidance would be appreciated

It sounds like your limit switches are active-low. Try inverting them in PnCCOnf (check-box in the setup tabs for each input).

thanks for the quick reply, I have already tried that with and without inverting, swapping them around in different gpio inputs, and nothing seems to make a difference, hence my posts.
I can post whatever files may help, I am just not sure which would be helpful.

(in stepconf I have them all inverted)

Your hal & ini are a good start

Of course, here they are.
also I have been fiddling with settings and in stepconf I had all limit switches inversed, if I do that on pncconf I get all joints on limit error, no error if I uncheck the inv box, however I also get no feedback detected from the G540 when a limit is activated, there are other confusing issues which will have to wait.

Thanks for the support
Eric

BTW, the hal and ini files are difficult to me to follow.

I dont think pncconf has direct g540 support so the assigned 5I25 GPIO pins for the limit switches are wrong

If you use a G540, the inputs are mapped like this:

INPUT1 GPIO13
INPUT2 GPIO14
INPUT3 GPIO15
INPUT4 GPIO16
