PyMata ====== PyMata is a high performance, multi-threaded, non-blocking Python client for the Firmata Protocol that supports the complete StandardFirmata protocol. A new version for Python 3.5, pymata_aio, can be found [here](https://github.com/MrYsLab/pymata-aio). The API can be viewed on the [wiki](https://github.com/MrYsLab/PyMata/wiki). ## Major features * __Implements the entire Firmata 2.4.1 protocol.__ * __Python 2.7+ and Python 3.4+__ compatibility through a shared code set. (If you are running Python 3.4 on Linux, please see note below). * Easy to use and intuitive __API__. You can view the [PyMata API Documentation here](https://htmlpreview.github.io/?https://raw.githubusercontent.com/MrYsLab/PyMata/master/documentation/html/pymata.m.html) or view in the Documentation/html directory. * Custom support for __stepper motors, Sonar Ping Devices (HC-SR04), Piezo devices and Rotary Encoders__. * Requires the use of FirmataPlus for PyMata - installation instructions may be found [here](https://github.com/MrYsLab/PyMata/wiki/Installing-FirmataPlus). * __Wiring diagrams__ are provided for all examples in the examples directory. * Digial and Analog __Transient Signal Monitoring Via Data Latches:__ * They provide "one-shot" notification when either a digital or analog pin meets a user defined threshold. * Analog latches compare each data change to a user specified value. * Comparison operators are <, >, <= and >= * Digital latches compare a data change to either a high or low, specified by the user. * Latches can easily be re-armed to detect the next transient data change. * Latches can be either manually read or a callback can be associated with a latch for immediate notification. * Optional __callbacks__ provide asynchronous notification of data updates. ## Callbacks Check out the example code on the [wiki](https://github.com/MrYsLab/PyMata/wiki). * Digital input pins. * Analog input pins. * Encoder changes. * I2C read data changes. * SONAR (HC-SR04) distance changes. * Analog latch condition achieved. * Digital latch condition achieved. * Callbacks return data reports in a single list format. * Polling methods and callbacks are available simultaneously and can be used in a mixed polled/callback environment. * Callbacks return data in a single list. ### The callback data return values | Callback Type | List Element 0 | List Element 1 | List Element 2 | List Element 3 | | ------------- | -------------- | -------------- | -------------- | -------------- | | Analog| ANALOG MODE|Pin Number|Data Value|Not Applicable | Digital|DIGITAL MODE|Pin Number|Data Value|Not Applicable |I2C|I2C MODE|I2C Device Address|Data Value|Not Applicable |Sonar|Trigger Pin|Distance in Centimeters|Not Applicable|Not Applicatble | Encoder|Encoder MODE|Pin Number|Data Value|Not Applicable | Latched Analog| LATCHED ANALOG MODE|Pin Number|Data Value|Time Stamp | Latched Digital|LATCHED DIGITAL MODE|Pin Number|Data Value|Time Stamp ## Control-C Signal Handler Below is a sample Control-C signal handler that can be added to a PyMata Application. It suppresses exceptions being reported as a result of the user entering a Control-C to abort the application. ```python import sys import signal # followed by another imports your application requires # create a PyMata instance # set the COM port string specifically for your platform board = PyMata("/dev/ttyACM0") # signal handler function called when Control-C occurs def signal_handler(signal, frame): print('You pressed Ctrl+C!!!!') if board != None: board.reset() sys.exit(0) # listen for SIGINT signal.signal(signal.SIGINT, signal_handler) # Your Application Continues Below This Point ``` ## Misc - Want to extend PyMata? See [Our Instructables Article](http://www.instructables.com/id/Going-Beyond-StandardFirmata-Adding-New-Device-Sup/) explaining how stepper motor support was added. Use it as a guide to customize PyMata for your own needs. - [Check Out Mr. Y's Blog Here](http://mryslab.blogspot.com/) for all the latest news! # Special Note For Linux Users Wishing to Use Python 3.5 # [pymata_aio is now available and for Python 3.5.](https://github.com/MrYsLab/pymata-aio) # [Check out the pymata_aio wiki!](https://github.com/MrYsLab/pymata-aio/wiki) This project was developed with [Pycharm](https://www.jetbrains.com/pycharm/) ![logo](https://github.com/MrYsLab/python_banyan/blob/master/images/icon_PyCharm.png)
