If you are not using the default IP address you must specify the IP address in the mesaflash command line:
./mesaflash --device 7i76e --addr 192.168.2.130 --readhmid
./mesaflash --device 7i76e --addr 192.168.2.130 --readhmid

Hi,
that makes all the difference!
And in the meanwhile I was wondering how it could find the board just by it's name![:dry: :dry:](/media/kunena/emoticons/ermm.png)
Now I understand!![:lol: :lol:](/media/kunena/emoticons/grin.png)
So Now I need to flash firmware in it for LinuxCNC?
Regards,
Jack

No, it should have proper firmware installed
You might need to change the firmware if you had a daughtercard
connected to one of the 26 pin expansion connectors for additional I/O

Hi PCW, thank you very much for helping me out.
For a friend, I'm helping to modify a lathe (Emco Compact 5 CNC), where the existing electronics is broken.
For this I would like to use LinuxCNC in combination with the 7i76e board.
The advantage is to learn LinuxCNC, instead of using EdingCNC.
It isn't hard to learn HAL, because of my electronics background, but nevertheless, I have to learn a lot new things for this to get it going.
On the lathe, I basically have two axis, and a spindle motor.
The spindle motor is a 180V DC motor, the motor controller has an analog 0-5V input.
On the encoder wheel, I replaced the existing two opto-sensors for 3 sensors, like so I have an A, B, and index signal, which the 7i76e should be able to handle.
Now the board seems to work fine, I run Pncconf, but honestly, I do have difficulty with all the setup parameters.
And maybe I don't need that.
What is the best direction (webpages, reading stuff) to continue with it?
Kind regards,
Jack.

You can choose a lathe (XZ) configuration in pncconf
For general LinuxCNC info theres:

There is.![:-) :-)](/media/kunena/emoticons/smile.png)
Feel free to come back with any questions. I don't think that any one person knows everything about LinuxCNC, but collectively we know most of it.

I've flashed with the right firmware, and all is okay... Or so it seems.
I've been struggling to get the encoder channels working - I've now built a PYVCP based DRO just to test the encoders, and it's bizzare. Only the first encoder (the one on the 7i76e) is working, but it's on both encoder 4 and encode 5 channels. I've got encoders on ports 1 and 2 on the 7i85, and neither of those are working.
First: any idea what's going on here? wiring issue? under-voltage issue? firmware issue?
Second: what is the correct sequence number of the encoders?
If I use a dedicated 5V power supply, any suggestions on the type I should use? Are grounded industrial DIN rail types okay, or am I better using a double insulated non-grounded wall-socket type?
Thanks

You need to have firmware that matches the daughterboard set you have
for example, a 7I76E+7I85 would use 7i76e_7i76x1_7i85x1D.bit
firmware.
LinuxCNC would need to be configured to use the added encoders

This sounds like you have a firmware that uses muxed encoders, such as those on the 7i77. These have 2 encoders on one set of pins to the FPGA card.
So, possibly, the 7i76 and 7i85 need to be swapped to the other connector?

That sound basically OK, Did you check the 5V at the 7I85?
Is the 7I76e jumpered t supply 5V to the 7I85?
What exact firmware did you use?
The encoder numbering of 7i76e_7i76x1_7i85x1D.bit is as follows:
7I85 (on P1) encoders 0..3
7I76E encoder 4 (and aliased encoder 5 which is an artifact of combining muxed
encoders with the non-muxed encoder hardware on the 7I76E)
