It is my understanding that for the Debian version of LinuxCNC libeditreadline-dev is being used as a GPL-v2 compliant alternative to libreadline and to avoid GPL-v3 conflicts. I have asked the Clear Linux team to see if that can be an option for them too.

I was able to enable i2c, but the instructions say use “sudo i2cdetect -y 1”, 1 doesn’t seem to exist for me, I can only detect 11 and 12 and neither show the 0x36 address.
I have confirmed that the pins are making good contact, so bad connection is ruled out.
Could it be the kernel configuration?

Can the startup errors be due the pullup resistors that has 7i80hd
and all pins before starting linuxcnc are at 5V ?

To turn on i2c

edit as superuser /boot/broadcom/config.txt and uncomment the lines relate to i2c.

then edit as superuser /etc/modules and either add i2c-dev or uncomment if it is commented out

reboot

That will get i2c up and enabled

Hey guys, I’ve add a Geekworm x1201 UPS to my Pi5 as I often get power outages at my place and wanted a bit of extra security.
I was able to access and change the EEPROM to get it to charge and power the pi5 from the batteries. But to change anymore detailed settings, like battery monitoring, It’s telling me I need to open Raspi-config. Which I obviously can’t using the Linuxcnc image. 

Here a link to the detailed instructions, suptronics.com/Raspberrypi/Power_mgmt/x120x-v1.0_software.html
unfortunately it’s all for the Raspberry Pi OS. 

Is there anyway I can make this work or am I wasting my time? 

 

Looks like it supports function 2 which would be a more natural
way to do bit input

Looks OK.

Probably here, as far as i can tell, everything else will inevitably lead to here, and google still seems to find the forum easily.

I have placed a simplified version of the configuration on the example of one of the most common 7i96s boards, as well as a diagram. They work just like the more complex options.
