Nanpy

Use your Arduino board with Python. http://pypi.python.org/pypi/nanpy

Overview

Nanpy is a library that use your Arduino as a slave, controlled by a master device where you run your scripts, such as a PC, a Raspberry Pi etc.

The main purpose of Nanpy is making programmers' life easier, providing them a powerful library to create prototypes faster and make Arduino programming a game for kids.

from nanpy import ArduinoApi

a = ArduinoApi()
a.pinMode(13, a.OUTPUT)
a.digitalWrite(13, a.HIGH)

I know, there are a lot of projects able to do that, but hey, Nanpy can do more!

Nanpy is easily extensible and can theoretically use every library, allowing you to create how many objects you want. We support OneWire, Lcd, Stepper, Servo, DallasTemperature and many more...

Let's try to connect our 16x2 lcd screen on pins 7, 8, 9, 10, 11, 12 and show your first "Hello world"!

from nanpy import Lcd

lcd = Lcd([7, 8, 9, 10, 11, 12], [16, 2])
lcd.printString('Hello World!')

really straightforward now, isn't it? :)

Serial communication

Nanpy autodetects the serial port for you, anyway you can manually specify another serial port:

from nanpy import SerialManager
connection = SerialManager(device='/dev/ttyACM1')

and use it with your objects

from nanpy import ArduinoApi
a = ArduinoApi(connection=connection)
a.pinMode(13, a.OUTPUT)
a.digitalWrite(13, a.HIGH)

You can specify how many SerialManager objects you want and control more than one Arduino board within the same script.

How to build and install

First of all, you need to build the firmware and upload it on your Arduino, to do that clone the nanpy-firmware repository on Github or download it from PyPi.

git clone https://github.com/nanpy/nanpy-firmware.git
cd nanpy-firmware
./configure.sh

You can now edit Nanpy/cfg.h generated file to configure your Nanpy firmware, selecting the features you want to include and the baud rate.

To build and install Nanpy firmware, copy Nanpy directory under your "sketchbook" directory, start your Arduino IDE, open Sketchbook -> Nanpy and click on "Upload".

To install Nanpy Python library on your master device just type:

pip install nanpy

To uninstall:

pip uninstall nanpy

To install the latest version from Github:

pip install https://github.com/nanpy/nanpy/archive/master.zip

How to contribute

Nanpy still needs a lot of work. You can contribute with patches (bugfixing, improvements, adding support for a new library not included in Nanpy yet, writing examples and so on), writing documentation, reporting bugs, creating packages or simply spreading Nanpy through the web if you like it :) If you have any doubt or problem, please contact me at [email protected]

Do you want to support us with a coffee? We need a lot of caffeine to code all night long! if you like this project and you want to support us, please donate using Paypal

Bug reports

• try the blink.py example
• try to test the function without Nanpy, using only Arduino code. If the problem remains then it is not a Nanpy bug.
• enable logging: import logging;logging.basicConfig(level=logging.DEBUG)
• attach the log messages
• attach your program. The program should be as small as possible which demonstrates the bug.
• check cfg.h. All needed functions are enabled?
• Run examples/firmware_check.py to check cfg.h again. All needed functions are listed?
• attach your cfg.h
• describe your hardware

Supported hardware

Uploading nanpy firmware for Arduino

I have problem with uploading firmware to Arduino. May be the way I try is wrong although I follow the instruction here https://github.com/nanpy/nanpy-firmware. Is there any other way to upload firmware to Arduino? I have tried the explanation here http://www.instructables.com/id/Arduino-Raspberry-Pi-Internet-Radio/?ALLSTEPS . It is really easy and working for me. But that version is version 0.7. Now I want to try for latest version. Can you show explain me the way to do it just simple way?

Uploading firmware to Arduino micro

Hello!
We got the firmware and example sketch running for the Arduino Uno.
It works smoothly :)
Now we tried with the Arduino Micro, which we would be needing for our prototype, but cant upload the firmware to the micro. Have you heard of any issues before?
Error Message when uploading: http://codepad.org/NiDRZDIe

Any help would be much appreciated :)

missing firmware folder.

makefile missing and can be located in the .9 release.

Add build test and CI

Possible firmware issue

I'm by no means an expert in the programming field, I've just started with an Arduino getting a speech synth chip to work. When trying to load some code that imports nanpy I get the following readout

E:\python>python serial.py
Traceback (most recent call last):
File "serial.py", line 6, in
from nanpy import (arduinoapi, serial_manager)
File "E:\Python 3.5.1\lib\site-packages\nanpy-0.9.5-py3.5.egg\nanpy__init__.py", line 12, in

ImportError: cannot import name 'arduinomethod'

The error is something to do with the arduinomethod(???) and I have no idea how I can fix the problem. Any help would be much appreciated.

Obtaining multiple addresses with DallasTemperature Class 'getAddress'

I am having trouble retrieving more than one address from the getAddress method.

I have two DS18B20's connected on Pin 10, at present getAddress() always returns the results from device 0. The getTempC method is working fine and receives the individual device readings, but I need to get the device address' for a transaction log.

I've tried to go through the firmware code however I am not overly familiar with C/C++..

Any pointers would be much appreciated!

Here's my python code.

from nanpy import DallasTemperature

sensors = DallasTemperature(10)
sensors.setResolution(9)
sensors.requestTemperatures()

for x in range(0, sensors.getDeviceCount()):
    temp = sensors.getTempC(x)
    addr = sensors.getAddress(x)
    print("This devices address is %s" % addr)
    print("The temperature, in Celsius degrees is %0.2f" % temp)

How to Use oneWire

Hello, Newbie on using Nanpy, how can i use oneWire library in my project. Thanks

supporting ARM

TODO:

• Arduino 1.6 (ARM and AVR) build tests with travis
• use #ifdef AVR for AVR specific code
• rename AVR only files (example: counter_avr.cpp)
• rename AVR only features (example: #define COUNTER_AVR 1)

Wire problem PCF8574

Hi,
Iv got Nanpy to do simple stuff such as moving motors and lighting LEDs (brilliant stuff btw ! ). Im trying to expand the IO ports of my Micro using a PCF8574 and i keep running into this error when i try the basic Demo program

>PCF8574 demo
address: 0x27
Traceback (most recent call last):
  File "PCF8574_demo.py", line 50, in <module>
    main()
  File "PCF8574_demo.py", line 15, in main
    pcf = PCF8574(a.wire, I2C_ADDRESS)
  File "/home/pi/Desktop/teststuff/nanpy/memo.py", line 20, in __call__
    value = self.func(*args)
  File "/home/pi/Desktop/teststuff/nanpy/arduinotree.py", line 141, in wire
    return Wire(self.connection)
  File "/home/pi/Desktop/teststuff/nanpy/classinfo.py", line 26, in getinstance
    (cls, cls_name))
nanpy.classinfo.FirmwareMissingFeatureError: <class 'nanpy.wire.Wire'> ['Wire'] is missing from firmware!

Any idea on what may be the problem ?
Thanks so much !

Refactoring and fixes needed in Nanpy core

Reported by Bartek Celary

char* readLineFromSerial()
{
    char* buffer = (char*)malloc(30);
    int i=0;
    char ch = '0';
    do {
        ch = Serial.read();
        if(ch != '\0' && ch < 255 && ch >= 0) {
            buffer[i++] = ch;
        }
    } while(ch != '\0');
    char* buffer2 = (char*)malloc(i + 1);
    buffer[i] = '\0';
    strcpy(buffer2, buffer);
    free(buffer);
    return buffer2;
};

I maybe misreading this but it looks to me there are 2 issues here. First: we can easily go beyond 30 chars and corrupt the memory (if there's no 0 char available from Rx), second performing 2nd malloc is not good for memory fragmentation.

cfg.h improvements

• turn on some features in default config
• missing #define should be the same as if it would be zero
• console and/or GUI generator for beginners
