Re: [Machinekit] Machinekit DE0_NANO why "Bus Error"

If you use Charles's DB25 breakout (which is the sanest and easiest way to interface), you can use the P2 header for steppers and an encoder with the same pinout as a Mesa 5i25 and the P3 for GPIO There are already threads on this forum about it This one has details including an image I made of the GPIO pinout on the P3 header, plus links from Charles to the schematics etc https://groups.google.com/forum/#!msg/machinekit/wqH_V52qdQY/GxaGaD7cBgAJ;context-place=forum/machinekit On 07/07/17 14:21, Sebastian wrote: Ok thanks a lot, yes than is the question for us how to access the existing GPIO using the pre-built image we have burned. Do you know where we can get these information?  Am Freitag, 7.

It is a matter of asking the right one. I have 2 machines using DE0-NANO + 7i76 boards providing multiple axes and full GPIO from the 7i76, and one XYZ milling machine just using the DE0-NANO to provide 3 axis hardware stepping and encoder on one header and using the GPIO bank through a breakout board on another.

We use this Image: http://deb.machinekit.io/uploads/de0-nano/debian-8.5-console-armhf-2017-02-14/. Our main problem is that every time we try access to the GPIO's over a C-program we get the same Error “Bus Error“.Our question is, is there a Demon who don't let us access to the GPIO's or what kind of mistake we made. On the fpga is a .rbf file that we have generate with Quartus where we can access to the GPIO's over PIO's. We have test that with a C-Program on the from Altera provided Console Image: http://www.terasic.com/downloads/cd-rom/de0-nano-soc/linux_BSP/ -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
