7i76ED+7i77 for analog signal was created by Hamel2020
Hi ..
I'm trying to use 7i76ED +7i77 mesa cards for my 5 axis welding machine , All my servo are using analog signal , I used the firmware 7i76e_7i76x1_7i77x1D.bit to flash it ..
1. I think I did it correctly ( please correct me if I'm wrong ) , I got the result as per the attached photo .
my question is : We I can defined my drive and encoder , because I did not see any place shows where I can input the setup for my X,Y,Z,A,C ..the manual of 7i77 shows drive 0-5 as a driver , but where I can find it in the setup .
2. I have the red light CR-16 always on ..
Thank you

Did you run mesaflash with the --reload option or power cycle the 7I76ED after programming?

OK that's the correct firmware, but pncconf will not know how to configure it.
It will require hand editing the plain 7I76e config to add the 7I77 support
(possibly copy pasted from another 7I77 config with sserial channel numbers
changed)
The 7I77 will not be detected by linuxCNC until the additional sserial channels are enabled in the hal or ini file

1. I’m totally confused , I can not save the configuration on the EEPROM , for the 7i76e , I did flashing , and went well but when I switch the power off , it goes back to the old configuration , is it jumpers issue or I miss something ?
2. I was able to configure 7i76+7i77 (without saving the configuration with green light at CR16) .
3. I used other configuration (5i25+7i77) then start to edit it …
But I do not know the correct expression for setting :
For example for PWM I used :
setp hm2_7i76e.0.7i77.0.1.analogout0- mimlim
setp hm2_7i76e.0.7i77.0.1.analogout0- maxlim
but it shows pin not found ..
also asking for the correct expression of the encoder since I will use both of feedback and pwm from the 7i77 card ..
Thanks

If you flashed the EEPROM with
mesaflash --device 7i76e --addr [card_IP_address] --write [bitfile_name]
it will stay (and its verified after writing)
The 7I77 digital section will be channel 2 and the analog section, channel 3
so:
setp hm2_7i76e.0.7i77.0.3.analogout0- mimlim should work
(you also need to enable 4 sserial channels with sserial_port_0=0000x)
mesaflash --device 7i76e --addr [card_IP_address] --write [bitfile_name]
it will stay (and its verified after writing)

Hi Peter , I really appreciate your help …
1. I was flashing the EEPROM with command :
mesaflash --device 7i76e --fallback --write [bitfile_name]
but now when I remove the fallback … the configuration was ok
2. I connected the servo as per the attached hal and photo , but always I get F7 ( which is feedback error)
By the way I connect the driver and servo motor to the computer as serial ( with the tuning software supplied by f the manufacturer company .. it works well and I was able to move the servo motor, but when I connect it with 7i77 I got that error ) .
Any advice ?
Thanks
