Frequency Counter block

[horcsab]

Hallo Peter!
Would it be a big job to add a dedicated frequency measurement block to the colorlight board?
I'm trying again with the 0-10V / 0-10kHz converter, but its implementation in the linuxcnc program is not ideal.
Regards,
Csaba

I think that is possible, but could you please specify your requirements.

The encoder module has already a counter, so this function could be added to this block. For this, a single wire encoder should be added (i.e. a pulse counter). The function to het the frequency is already implemented in that case.

Hallo Peter!
I'm trying to use the encoder module in counter mode. But it doesn't work.
I would use it here on the J4 connector. This is just a trial version.

Json section:
{
"module_type": "encoder",
"instances": [
{"pin_A":"j1:2", "pin_B":"j1:4", "pin_Z":"j1:5"},
{"pin_A":"j4:0"}
]
}

In the hal file, encoder.01.counter-mode TRUE keeps giving an error because it can't be found.
What syntax should I use it with?

In halrun, I only see these:
