Changes in configuration files generated in pncconfig for 7i76 to 7i78

7C81 configuration for 7I78 on P1, INM on first 12 P2 pins

The inm module supports up to 4 MPG encoders,
it also has built in input filtering/debouncing.

The last 5 P2 pins are left as GPIO so can be inputs/outputs
as needed


 

 

Thank you very much, you are great.

Unfortunately, the situation is anything but simple… I reinstalled Bookworm, but the command:
`sudo mesaflash --spi --addr /dev/spidev0.0 --device 7c81 --readhmid`

doesn't work:

- open: No such file or directory
- No 7C81 board found

The following works:

`halcmd -kf`

`halcmd: loadrt hostmot2`

`halcmd: loadrt hm2_rpspi`

`halcmd: show all hm2`

However, I don't know how to write a new bitfile. That is, the equivalent of:

`sudo mesaflash --spi --addr /dev/spidev0.0 --device 7c81 --fallback --write bitfile-name`

I tried installing an older version of LinuxCNC – Buster. However, the libraries for installing mesaflash are missing and cannot be installed because the repositories for this version no longer exist.

What is the result of

ls /dev/spidev*

cnc@raspberrypi:~$ ls /dev/spidev*

ls: cannot access '/dev/spidev*': No such file or directory

What RPi model are you using and what image are you using.

spi hasn't been enabled in config.txt
