halcmd (and hal)  are fine with true/false for bit types:

pcw@pcw-HP-Compaq-Elite-8300-USDT:~/linuxcnc-dev/src/hal/components$ halcmd setp hm2_7i96s.0.ssr.00.out-00 true
pcw@pcw-HP-Compaq-Elite-8300-USDT:~/linuxcnc-dev/src/hal/components$ halcmd getp hm2_7i96s.0.ssr.00.out-00 TRUE

pi@raspberrypi5:~/linuxcnc/nc_files $ ./M101
bash: ./M101: cannot execute: required file not found

Likely means that bash was not found.



 

 Sorry, I really didn't comment out these lines in Hal when I tested it from the command line. Here are the error messages.

pi@raspberrypi5:~/linuxcnc/nc_files $ bash M101
' invalid for bitvalue 'True
<commandline>:0: setp failed
: numeric argument required
pi@raspberrypi5:~/linuxcnc/nc_files $ 
 

Tried it two ways, still doesn't work. In the first case it gives an error.

pi@raspberrypi5:~/linuxcnc/nc_files $ ./M101
bash: ./M101: cannot execute: required file not found
pi@raspberrypi5:~/linuxcnc/nc_files $ bash M101
<commandline>:0: pin 'hm2_7i95.0.ssr.00.out-01' is connected to a signal
: numeric argument required

Hello everyone! This is my first post on the forum. I have a problem with setting up custom M codes on Raspberry + 7i95. I need additional outputs to control the equipment. Just turn on and off some outputs on the 7i95.
In principle, nothing complicated, but when executing custom M code, linuxcnc does not display error messages and the pin states on the 7i95 outputs do not change.
There are no changes in halshow either.

I use this image www.linuxcnc.org/iso/rpi-5-debian-bookwo...25-01-27-0140.img.xz

Here is one of the commands (M101)
#!/bin/bash
halcmd setp hm2_7i95.0.ssr.00.out-01 True
exit 0

Even if you intentionally make a mistake in the M command file, linuxcnc still does not give any error messages.
Has anyone encountered this problem on Rasberry Pi?
