Struggling to get all encoders to show up on 7i77 via 7i94T was created by workshop54
I've been working on this all day and it's starting to drive me a bit crazy.

I'm using a 7i77 connected through a 7i94T and trying to get at least 3 of the encoders to show up in halcmd show pin. So far, only two encoders are visible.

Here’s what I see:
Code:
~/linuxcnc/configs/maho_mh400e$ halcmd show pin | grep 7i77 26 float OUT 0 hm2_7i94.0.7i77.0.0.analogin0 26 float OUT 0 hm2_7i94.0.7i77.0.0.analogin1 26 float OUT 0 hm2_7i94.0.7i77.0.0.analogin2 26 float OUT 0 hm2_7i94.0.7i77.0.0.analogin3 26 s32 OUT 0 hm2_7i94.0.7i77.0.0.enc0.count 26 bit I/O FALSE hm2_7i94.0.7i77.0.0.enc0.index-enable 26 float OUT 0 hm2_7i94.0.7i77.0.0.enc0.position 26 s32 OUT 0 hm2_7i94.0.7i77.0.0.enc0.rawcounts 26 bit I/O FALSE hm2_7i94.0.7i77.0.0.enc0.reset 26 s32 OUT 0 hm2_7i94.0.7i77.0.0.enc1.count 26 bit I/O FALSE hm2_7i94.0.7i77.0.0.enc1.index-enable 26 float OUT 0 hm2_7i94.0.7i77.0.0.enc1.position 26 s32 OUT 0 hm2_7i94.0.7i77.0.0.enc1.rawcounts 26 bit I/O FALSE hm2_7i94.0.7i77.0.0.enc1.reset 26 float OUT 25.02753 hm2_7i94.0.7i77.0.0.fieldvoltage 26 bit OUT FALSE hm2_7i94.0.7i77.0.0.input-00 26 bit OUT TRUE hm2_7i94.0.7i77.0.0.input-00-not // omitted other input pins for brevity 26 bit IN FALSE hm2_7i94.0.7i77.0.0.output-00 // omitted other output pins for brevity 26 bit IN FALSE hm2_7i94.0.7i77.0.1.analogena 26 float IN 0 hm2_7i94.0.7i77.0.1.analogout0 26 float IN 0 hm2_7i94.0.7i77.0.1.analogout1 26 float IN 0 hm2_7i94.0.7i77.0.1.analogout2 26 float IN 0 hm2_7i94.0.7i77.0.1.analogout3 26 float IN 0 hm2_7i94.0.7i77.0.1.analogout4 26 float IN 0 hm2_7i94.0.7i77.0.1.analogout5 26 bit IN FALSE hm2_7i94.0.7i77.0.1.spinena

I’ve double-checked the firmware:

My HAL config includes:
Code:
loadrt hm2_eth board_ip=192.168.1.121 config=”sserial_port_0=300xxx”

The SmartSerial section seems to be working fine; analog IOs and digital IOs show up correctly.

But I expected more encoders from the 7i77 to appear — at least enc2..enc4 — and I can’t figure out what I’m missing. Is there anything I need to change in the firmware, or is my HAL config wrong?

Any help would be very appreciated. I’m just trying to get basic encoder feedback working for now before wiring up the rest.

Thanks in advance!

That's an odd error, I'll see if I can duplicate it here.

Have you had any communication errors? The only time I've seen something like this
before is where there were major communication issues.

That is, can you:

EDIT change IP address

sudo chrt 99 ping -i .001 -c 60000 -q 192.168.1.121


Without any dropped packets?


Note that 10.10.10.10 is suggested as the 7I94T IP address as 192.168.1.121
often overlaps local NAT ranges.


Note, checked a 7I94 with 7I77 firmware:  7i94t_7i77d.bin  and all encoders
showed up:

Ahhh, there they are.

I was doing grep 7i77 instead of grep enc.

Now I notice that the encoders are actually directly under the 7i94T, instead of the 7i77.
This makes me feel like a total newb again. (Well, I am in LinuxCNC, but not in programming)

Running the card on 192.168.1.121 works fine for me because I changed the NetworkManager config.

I tried to get the card on 10.10.10.10 with mesaflash —device 7i94t —addr 192.168.1.121 —set ip=10.10.10.10, but that doesn’t work for some reason.

The chrt command you gave me showed no packet loss.
Code:
~/linuxcnc/configs/maho_mh400e$  sudo chrt 99 ping -i .001 -c 60000 -q 192.168.1.121 PING 192.168.1.121 (192.168.1.121) 56(84) bytes of data. —- 192.168.1.121 ping statistics —- 60000 packets transmitted, 60000 received, 0% packet loss, time 60022ms rtt min/avg/max/mdev = 0.137/0.258/0.477/0.030 ms

You change to the EEPROM IP address (default is 10.10.10.10 )
by moving the IP address setting jumper (and power cycling)

What you did was re-write the EEPROM IP address to 10.10.10.10 (it was already that)
