Huanyang VFD RS485 / Modbus
OttoMeister
Now I try to update to an newer version of debian and machinekit, but i have some problems. If I compile the user space component for controlling a huanyang spindle, it compiles without trouble but wont communicate with the VFD. The newer version wont compile at all. My computer skills are not good enough to find the problem. So here are my question:
- Has anyone running an Huanyang VFD over Modbus with an actual version of machinkit?
- How about VFD over Modbus from different manufacturer?

I am using an 2.2kW Huanyang frequency converter for my spindle on an BeagleBone black. It runs pretty fine with a old image (bone-debian-7.8-machinekit-armhf-2015-04-26-4gb.img.xz).
Now I try to update to an newer version of debian and machinekit, but i have some problems. If I compile the user space component for controlling a huanyang spindle, it compiles without trouble but wont communicate with the VFD. The newer version wont compile at all.
How are you building it?
What errors do you get?
Inserting that sub dir into the MK source tree, builds the component without problems.
It is intended to be built within the source tree, not externally.
Since we don't have that component available, I will look at pulling it into the repo and then it will be available from packages too.
Testing will be down to you, I don't have one of these to try it on. ;-)

Compile and run without problem.
Then I connect Internet and make update and upgrade, also update machinekit, machinekit-xenomai, and many more....
Neue Version: machinekit_0.1.1497866711-1mk.travis.master.git8df407f6~1wheezy_armhf.deb
Start machinekit:
spindle-vfd: device='/dev/ttyUSB0', baud=9600, bits=8, parity='none', stopbits=1, address=1, verbose=1, PID=1739
Opening /dev/ttyUSB0 at 9600 bauds (none)
./hy_vfd.bin: symbol lookup error: ./hy_vfd.bin: undefined symbol: hal_malloc
Now download again standalone version from cnczone.org. Compile without errors, start new bin exact same way like old bin. Loads with no error. Axis-Gui starts with no error but can not communicate.
I will download the source of machinekit and try to integrate the source from linux-cnc. But it will take some time to do so…..

Looks like it is not linked properly.

https://github.com/machinekit/machinekit/pull/1221 is pending merge.
It builds the component, so that will be in the packages once merged and you will be able to update and test
before too long.

You don't have to

It builds and when I commented out the check for a serial connection (because I don't have the hardware), loading it created the component and all its pins.

However there is a problem with package builds at present, so the new package containing it is not yet available.
A RIP build will work fine however.
I will advise when new packages are available, don't know what the problem is at present.

Ok, thx a lot, this happening sooner than i thought.
So I made a “git clone https://github.com/machinekit/machinekit.git” but had a lot off problems with dependencies. Looks like a recent machinekit will not compiel on old Image. So I wait just a little bit and will then test it via “apt-get install machinekit”
So back to my old question:

You are looking for machinekit-<kernel>_0.1.1497941186-1mk.travis.master.gitdf9c7823~1<distro>_<arch>.deb
So back to my old question:
- Has anyone running an Huanyang VFD over Modbus with an actual version of machinkit?
- How about VFD over Modbus from different manufacturer?

So I installed a new
image ->
bone-debian-8.7-machinekit-armhf-2017-02-12-4gb.img.xz
Made
update and upgrade -> machinekit-<kernel>_0.1.1497941186 was
installed!
Problem with new setting from github config-flies so
used my old - and it works !!!!!!!!!!!
My working setup files
will come later after more testing.....

If you find the configs can be improved, or even just have a full working set for a BBB, send a link
to them and I will look at incuding them as examples.
Don't suppose too many (or any) people are using this currently.

Here are my settings, I don not think the config delivered with the hy_vfd is good for something. Anyway thank you very much. Hope that others with Huanyang can benefit from this as well.
I'll look at it properly tomorrow
