Hi Gene,
I was able to use your pyvcp information along with the web documents to get my
own slider working.
In the CAN message screen grab you can see id=218, dlc=4, and the first two
bytes representing 0x0032 in Little Endian format. That value in decimal is 50.

Hi Andy,
The output below shows CANopen PDO message #2 (0x300) to ID 0x18, 1 byte,
alternating between 0x01 and 0x00 being issued once per second.

For this application I think that a Pyhon userspace component using

I'm starting the next phase of a small project. I just about have the power
draw bar ready to mount.It's controlled by a small processor with two
buttons for load and release which runs the air valves which move the pneumatic
cylinder and spin butterfly impact wrench.

I am not sure I understand the answer.
Serial comms is a pretty fundamental thing. You should see a whole load of
ports in /dev
And screen
I see you used "lspci" and the port was not there.
Try booting the OS that sees the port then go to /dev/serial/by-id
and have a look.Ports there are names for their hardware locations
While booted up on that system try lspci.

The best way to test serial ports under Linux (or any other OS) is to make
a loopback device.This is a fancy name for a short length of wire that
short the Rx and Tx pins. You should then be able to read back every
byte you send. It loopback fails then you know the promlem is at your end

Greetings all;
One of the things I occasionally do is run a couple programs to talkto a
trs-80 computer running in the basement, which has 3 serial ports on it,
and the one that works with drivewire is the bitbanger, running at about
155 kilobaud. drivewire is written in java and apparently

You can certainly use the serial port status lines as extra IO for such uses:
