7i76e+8i20 pncconf issues
8 years 7 months ago #107787
by blazini36
7i76e+8i20 pncconf issues was created by blazini36
Working on setting up a 7i76e (which runs fine by itself) with a 8i20 to control a brushless DC motor with hall sensors. The 8i20 is connected to the 7i76e serial TB. Pncconf generated a hal file with some errors, some of which I can fix, some I'm not sure about, LinuxCNC won't start with this HAL file, likes to complain about missing pins:
Pncconf originally generated the wrong BLDC "personality" and used encoder commutation. this was likely my error running through the wizard but I commented the unused pins out and changed personallity to =h. For some reason "addf bldc.1 servo-thread" was generated which I commented out, I'm not sure why that second bldc function got added. All of the pins generated referred to "bldc.9.pinname" which linuxCNC complained about until they were changed to "bldc.0.pinname" At the moment it's complaining about:
Pins not found. I'm not sure why they came out with 2 dots after the channel, or if the pins are not found because the 8i20 was not found. Is there any way to check for communication between boards?
