Milk-v RISC-V
Sir, How are yhou ?
I installed the Misty on my MILK-V DUO S, i used the PIP
When i try to execute the bc --ini ./bc.ini
I am getting this
[root@milkv-duo]~# bc --ini ./bc.ini
Traceback (most recent call last):
File "/usr/bin/bc", line 577, in
Can you help me ?
Hi,
Please compile it on your architecture and install it.
https://github.com/riptideio/misty?tab=readme-ov-file#installation-and-usage-for-developers
That would make sure that the shared library is built for your system.
Thanks.
Bye, Raghavan V
Hi!!!!!!!!!!!!
The MILK-V Duo S only works with cross-compile...
Can you compile to me ?
got progress on cross-compile...
Please, what means this error ?
I want to use MSTP on ttyS1
thanks
[root@milkv-duo]~# bc --ini ./bc.ini

I will do more tests soon
hi, I found a bacnet mtsp server, wrote in C++ https://github.com/chipkin/bacnetservermstpexamplecpp?tab=readme-ov-file i executed it...

On bacnet client...
witch parameter i put on bacnet prompt >
?
My milk-v is connected (using RS485) to the PC...
Thanks!
I see that agent was off... then i changed the Milk-Duo S to run as ARM, not RISC-V... And...
Hi, is there some python example, where i can read some analogvalue from BACSERVER, but not using the console. but directly on python source code ?
Very good progress.
I recall doing a bacnet client without the Console. I tried looking for it, but could not find it.
But here is the broad idea.
(1) Change the LocalDevice initialization to not use the ini. You can pass the parameters directly.
this_device = LocalDeviceObject(ini=args.ini, **mstp_args)
(2) Remove creating the console. You dont need it anymore.
# make a console
this_console = BacnetClientConsoleCmd()
if _debug: _log.debug(" - this_console: %r", this_console)
(3) Now after you make the above changes. You will not have a way to Trigger it, right ? So you can use the PulseTask like this and trigger it.
class PulseTask(RecurringTask):
def __init__(self, app, interval=None, offset=None):
super().__init__(interval, offset)
self.install_task()
self.app = app
def process_task(self):
self.app.fetch_values()
# Use it in the main like this
# make a simple application
app = BACnetClientApplication(address)
app.start()
PulseTask(app, interval=10 * 1000)
The way I tested it was using server from bacnet-stack (https://github.com/bacnet-stack/bacnet-stack).
The bacnet-stack also has a binary bacepics which lists all the objects and the current values.
Can` you fix this code that i tried ?

Thanks to the help
In parallel, i did a Python app that make communication with console using PIPE
Hi,
I just added a non-console polling bacnet client in the samples. It is self contained. You can pass the device path of the serial device , baudrate etc , it will do whois, find out the points and keep polling them every 10 seconds. It prints and also writes it into a CSV.
You might find it useful.
I would suggest that you start with a new virtual environment, clone and do
pip install .
and run
python samples/polling_bac_client.py
Please note that the directories have been moved around.
Please let me know how it goes
Hi, Please have a NEW virtual environment where you dont have any of the old builds.
(1) clone the misty project
(2) at the root do
pip install .
This will build the sources and the install it in the environment
(3) Try running the sample
python samples/polling_bac_client.py
You need to go to a new virtual environment first where you have nothing installed. This is typically done by running python -m venv my_venv source my_venv/bin/activate
git clone https://github.com/riptideio/misty.git cd misty
builds the C library and installs in editable mode
python -m pip install .
see what parameters you can give (e.g. interface path /dev/ttyS5 or
whatever) python samples/polling_bac_client.py --help
most likely parameters (assuming you are doing 38400 baud rate )
python samples/polling_bac_client.py --interface /dev/ttywhatever

Remember that samples/polling_bac_client.py does NOT make use of the ini file. It only takes the parameters from command line
Hi @raghavan97 :)
I had to make some changes on MILK-V to make work....because MILK-V Duo does not have make and gcc..etc
See if this feedback is ok on polling example

This looks fabulous. You now have a non-console based application that will keep polling and getting the values. I hope this is what you were chasing.
Can you run it until it says
Wrote records.
and stops scrolling on the screen, do a ctrl-C . It will stop the program.
At that point take the snapshot.csv and send it over here.
