Hello,
we have nv200 device and trying to use your script and testing it on ubuntu 18 but we are getting below error
python ex1.py
PORT: /dev/ttyS0
##/dev/ttyS0##
Segmentation fault (core dumped)
also please suggest any best solution for this
also help us for payout with nv200
thank you
Use a Queue
rather than a string to handle the actions
may be more adapted (L118)
It's clearer and you can get rid of ACTION_SIZE
and i
logic.
Here is an example on how you would handle it:
from queue import Queue
def __init__(self, *args, **kwargs):
self.actions = Queue()
def do_actions(self):
while not self.actions.empty():
action = self.actions.get()
# do something with action
def add_action(action):
self.actions.put(action) # instead of self.actions += action
This is also much easier to make thread-proof in the future, when you have ATMs with octo-cores... π
python3 main.py
PORT: /dev/ttyACM0
##/dev/ttyACM0##
Segmentation fault (core dumped)
why i am having that error message
Hi,
1 ) I want to run NV11 using IF17/IF18 Interface converters do I need any Software development kits from ITL or any other software/drivers ?
2 ) This python package is suffice enough to run NV11 ?
3 ) On which Linux flavor it is stable, because i am getting error during the installation of this package in windows machine ?
The code has multiple PEP8 violations to be fixed, including but not limited to:
two blank lines before a class declaration (L12, L17, L25, L31, L35)
use new style classes: class ClassName(object):
(L35)
2 spaces before comment: #
(L44 and more)
block comment should start with a pound and a space after it (L48, L91, L199, L204, L315)
missing spaces around operators: 3*x
-> 3 * x
, self.actions+="y"
-> self.actions += 'y'
I'm also leaving here a couple other minor issues which are not exactly PEP8:
use .format
instead of %
for string formatting.
cannot return value from init (L52, L66, L72, L95, L101)
If you need a catastrophic failure here, raise an exception, preferably a custom one for clarity.
use setup_req.UnitType in {0x06, 0x07}
instead of or
L90
Using set membership will make your condition shorter and more readable, esp. if you need to add another value
later on.
In my opinion I would remove the t1
variable or if you want to keep it, use a clearer name such as loop_thread
(L102)
variable ACTION_SIZE
should be lowercase. (L116)
This is irrelevant once #3 is fixed
return (0,0,events.event)
is present is almost every if
/elif
block (L214-L303).
This version is a bit more readable and avoid the repetition:
if events.event == Status.CUSTOM:
return something_custom
elif events.event == Status.OTHER_CUSTOM:
return other_custom
return 0, 0, events.event
I believe return (0,0,NO_EVENT)
should be placed in the except ValueError
block referenced in #4
.
I always get this when calling sync()

There is some copy/paste on those set_route_...
and other action methods (L334-L366).
Use a helper method instead:
class eSSP(object):
def _action_helper(self, amount, currency, prefix, action):
self.actions += action
self.actions_args['{}_amount'.format(prefix)] = amount * 100
self.actions_args['{}_currency'.format(prefix)] = currency.upper().encode()
def set_route_cashbox(self, amount, currency="CHF"):
"""Set the bills <amount> in the cashbox
NV11: Set the bills <= amount in the cashbox"""
self._action_helper(amount, currency, 'routec', 'c')
Hello Minege! First of all, wanna thank you tour python implementation of eSSP, saved us lots and lots of time. Great work!
Although, we've currently got a problem when we disable_validator() and then, when the machine should be activated, enable_validator() sometimes doesn't enable it, and even if it does, we continue to see "Poll Disabled" in logs each time in event looping.
Could you propose a code snippet to correctly disable and enable validator, each time returning to a valid working state? Would be awesome thank you.
Use Enum
rather than variables or magic numbers for status and actions
I.e. go from this
if self.actions[0] == "y": # Payout next note ( NV11 only )
To something like:
Definition
class Status(Enum):
OK = (1, "debug message ok")
FAIL = (2, "debug message fail")
# ...
def __init__(self, value, debug_message):
self.value = value
self.debug_message = debug_message
def __int__(self):
return self.value
def __eq__(self, other):
return self.value == other
Usage
from sys import stderr
from constants import Status, Action
try:
self.print_debug(Status(events.event).debug_message)
except ValueError:
print('Unknown status: {}'.format(events.event), out=stderr)
if events.event == Status.SOME_STATUS:
pass
# do something custom
elif events.event == Status.SOME_OTHER_STATUS:
pass
# do something different
#...
This also gets rid of the
from constants import *
which is never a good idea

Enum
class definition

Hello
I'm using NV10 and don't know what function to use to take the banknote values ββand write the total amount to a variable.
This library implements that in a loop the bill acceptor is polled and the text is output to the console, and I need to take the value of the bills.
Please share an example.

Hi. get_last_event() always return (0, 0, 0) I have a NV11, S.O. armbian and running on python 3.7.3 Thank You.
in "lib/random.c" on line 146
asm ("RDTSC" : "=A" (result));
Does not compile on ARM/ARM64 based Raspberry PI computers for obvious reasons.
A better more cross-platform compatible approach would be to support something like "rng-tools"
Hi, I connect Smart coin system and Smart Payout with two USB cables, but when I try to put coin into Smart Hopper, the door didn't open. And find that the program only find unit type 9 or 6, but the unit type of Smart Hopper is 3. They can run perfectly on Windows with offical software. Can you guide me how to do? Thanks, regard!
