Motenc Lite

Current release: 2.7.14

Motenc Lite

I/O levels are read or written to physical pins, we can measure signal levels

DAC write does not take effect on physical pins, we can not measure any adequate levels

is there eventually something not perfect in motenc driver in release: 2.7.14

Is the dac_write function added to a thread?

linuxcnc.org/docs/2.7/html/drivers/motenc.html

we think so, in the picture the dac value is shown

I thought you were saying that the HAL value is not being written to the hardware?

What does "halcmd show funct" show (in a terminal)

er@rosa:~$ halcmd show funct

You are not using adc-read, is that deliberate?

Can you attach the HAL file?

er@rosa:~$ halcmd show funct

Are there other HAL files? That one has no connection from the PID to Xoutput (etc)

it is almost same as the installed example of the image distribution 2.7.14


some news:

the same configuration works perfect on wheezy 2.7.14 when using together with any appropriate mainboard

but not works with eBPC-300 Alptech Elektronik GmbH (seems hardware is not compatible with Motenc Lite)

I am sorry for coming up with my request here yesterday and many thanks for all your famous work at all this stuff !

That is very strange. Very strange indeed.

It might be a faulty PCI port, or maybe just a dirty one.
