[Machinekit] Mesa 6i25 Smart Serial ports work with halcmd HAL-file, but not with python-HAL

[d***@gmail.com]

Hello everyone,
we have the following problem with machinekit (latest version from
repositories, debian stretch):

If we launch machinekit with an original (linuxcn-style) HAL-file:

loadrt hostmot2
loadrt hm2_pci config=" num_encoders=1 num_stepgens=4
sserial_port_0=00xxxxxx "

we can read out a 7i76-daughterboard digital in pin via halmeter.

On the other hand, if we use a python-HAL:

rt.loadrt('hostmot2')
rt.loadrt('hm2_pci', config=' num_encoders=1 num_stepgens=4
sserial_port_0=00xxxxxx')

halmeter shows the pins, but they show only false, regardless of the actual
input value.

Do you have any ideas?

Best regards
Dennis

halmeter shows the pins, but they show only false, regardless of the actual input value.

Which pins are that?

What does `halcmd show pin hm2_5i25.0` say?

Do you have any ideas?

Have you inspected /var/log/linuxcnc.log after setting `export DEBUG=5` in the terminal you run your python file?

Have you added the read, write and pet_watchdog functions to your thread?

Have you started the thread?

Thank you so much Bas,
indeed we forgot to add the write and watchdog functions to our thread!
