usb485 to huanyang vfd

hi
i did also face problems on 2.9 from a recent 2.8 on the vfd
putting everything from the main HAL to a postgui Hal did solve almost all externel invirerment problems
the new interpreter is very triggy on externel in and out signals to the main hal system even on servotread
the postgui seams to be handled mutch more timing friendly as it has been in 2.7.x

Attached is a picture of the error messages, as well as my cusom.hal file and custom_postgui.hal

There should be a button at the bottom of the error dialog that lets you copy all the text to paste into a text editor, or directly in to a message here.

But if I had to guess I would say that the driver is not finding the VFD.

Are you sure you are configuring the serial port correctly?

Last time when I set up the VFD once I has able to run the following (which is just straight copied from the custom.hal file) in the terminal and verify the connection was good, I was able to get axis to load. But this time I can run the following in the terminal just fine. Seems like every other time I plug in my USB it switches between USB0 and USB1, so I have been updating that before I start, just using ls /dev/tty* to verify I am on the correct port. I will post the entire error message next time I try it.

- halcmd loadusr -Wn spindle-vfd hy_vfd -S 24000 -F 400 -n spindle-vfd -t 1 -d /dev/ttyUSB1 -p none -r 19200 -s 1 -g
- halcmd setp spindle-vfd.enable 1
- halcmd show pin

There are ways to make the port name consistent:

(first google hit)

Thanks, I will setup that up. I just haven't super cared until I can get axis to work.
