OK

So I don't see any documentation for PktUART and it would require a custom
bit file. So that is something maybe I could add later in a custom bit file?


Sure



In the meantime I just need something that actually works that has 3 pwm
outputs and 3 encoder inputs. So can you suggest a bit file that I can use
as is and may also be a starting point for a custom file that adds 3 UARTS?



Any of the SVST bitfiles should work

Thats probably because that was built with a batch file and theres a
source code
tweek needed for the UART module because it uses a differeent register
stride
  For this and other reasons, I would suggest not using the UART and using
the
PktUART instead. This wil likely require a custom bitfile

What is the md5 checksum of the bitfile you are using?

zephyr@Clausing:~/linuxcnc/configs/7i80/7i80/configs/hostmot2$ md5sum

7i80hd_25_2x7i65.bit
d3f91185e95027ca93ae00a1334d852d  7i80hd_25_2x7i65.bit


That matches so its probably a bad bitfile. I thin most of those bitfile were 
made automatically a long time ago and may have timing issues


I can remake it if you wish


But this may be all academic at this point. I think that even if I get the
file loaded with BSPIs the stuff
that I will need to figure out to make this all work seems difficult and
may not be worth the time.

So what I _really_ wanted is a simple SPI interface to send current command
to my drives, which
I thought would be simple to do, however, now I think I should just use a
bit file that was intended to work
with a card like the 7i33.  So I found something that I like called
7i80hd_25_svua8_4. I think this is for a 7i33 but it also
has some UARTs as well. I would like to make use of the UARTs for
non-realtime communications with some of my
devices such as SICK hiperface encoders to read the absolute position and
or maybe communications with some of
my drives.  Instead of using the SPI passing simple current_magnituce to
the drive I will just use the PWM output as the
current command like an analog servo in torque (current) mode.

If that really all does work I feel like I may be more competent hacking
the VHDL code for the FPGA to add my own SPIs that
just look like the PWM registers to LinuxCNC. When I had a real job I used
Altera (now Intel) Quartus with SOC (dual ARM with
FPGA) so using the Xilinx stuff does not seem as challenging as linuxCNC
code.

but when I load the 7i80hd_25_svua8_4 and then run my simple hal file using
halrun I get a different error
hm2/hm2_7i80.0: inconsistent Module Descriptor for UART Transmit Channel,
not loading driver.

so, do I need to load something like mesa_uart first? that does not
appear in the list of 2.8 or 2.7 man pages so I suspect
I need to do something different but a lot of the 2.8 man pages are missing

Re: [Emc-users] motherboard that plays well with 7i43

[dave engvall]

My thinking is that the 7i43 is best used for rt tasks with an EPP port, 
hence the problem. I should have been more explicit.   The plan is mb -> 
7i43 -> 7i42 for stepper-servos.

A related question I have is "Does choice of mainboard matter?"  I'd guess
if you are using the USB interface it wouldn't.

I was thinking of using the Ethernet interface Mesa board but then read it
needs a dedicated Ethernet port in the host PC.  This means buying,
installing, and configuring an Ethernet card. The PC or any PC today
already has half a dozen USB ports.  Even a Raspberry Pi has 4 USB ports
and might work well for this.

But my question is not about using a specific PC, but rather if it matters.

Peter,

Thanks for verifying this in your environment.
When you say communications issue do you mean something other than
electrical noise?

I doubt that there is a noise issue with my communications as right now I
am in a pretty
good environment. There are no drives or other noisy devices running, the
mesa hardware is mounted to a 3/8" thick grounded
aluminum sub panel with standoffs. The 5v power supply is ungrounded but
supplied through a shielded cable with the shield
single point grounded to the subpanel. The power looks clean on a scope.
The subpanel is connected to the PE (protective earth)
for the building. The ethernet CAT5E UTP cable is maybe about 3' long.

If I read the FPGA hmid using mesaflash I also read 65535. If the data was
bad from noise then wouldn't
the packet be dropped (bad crc) and other data besides the idrom value be
incorrect?
but the mesaflash --readhmid returns all of the other info that is expected
- i think.

Re: [Emc-users] can I hide the nativecam interface

[Rob C]

Yes nativecam will work for milling, plasma and lathe operations.
unfortunately its not been updated to python3 .. so if you use it on a
debian bullseye or linuxcnc master build it won't work :(

I've tried to have a go at making it nativecam + python3 functional but
failed but really like nativecam.

I use PlasmaC for my plasma setup so like to be on the bleeding edge of
development (master)  hence I can't use python 2 + 3 unless I went back
to debian buster which I may do eventually (busy doing other things
(noncnc) at present)

The two config files .ini and .hal are generated by stepconf

I'm actually using mousepad and nano as editors.

>From a quick look, in your .ini, your geometry line is xyz, 3 axises, but 
you then define xyzab, 5 axises later, and the .hal is missing the A and 
B stuffs. Its a bit short for a hal file too as many of the "net" 
statements don't have enough arguments.

A net statement should have

net name-of-net <= src => target [target] [target]
one src, and as many targets as you need
and then later in the file if needed, you can:
net same-name-as-above => target target 
for additional fanout if needed.
You can also do the second form in the postgui if needed if the target 
doesn't exist until the gui is running.

My stuff is a bit like topsey, it grew and grew from hand added stuff, 
and even my simplest lathe's hal file is 600 lines including comments, 
with some approaching 1000 LOC but have line after line of comments so I 
don't forget what I was doing 3 years later. Pleading guilty to being an 
old fart who does not well remember what he did 3 years ago. At 87 the 
wet ram does not refresh as well as it did at 47. :(

The other thing I note is that you are using gedit as the editor, and 
that may explain the short hal file. gedit likes to play 42 pickup with 
your stuff whenthe deck has 52 cards, please uninstall gedit, and 
install/use geany which doesn't have that bug. gedit looks nice, but it 
will eat your lunch /and/ dinner fixing its faulty saves, get rid of it, 
with prejudice. rm it on sight.

Cheers, Gene Heskett.

[Valerio Bellizzomi]

Attached are my .ini and .hal files.
Can you tell me what is missing there?
