Hands-on MicroPython Programming Examples for Edge Computing: Part 2. In our first post in the MicroPython programming for the edge series, we talked about how to collect sensor readings and make sense of them using the Digi XBee3 Cellular LTE-M Kit, as well as Digi's free configuration software, XCTU, and some simple MicroPython code 15 Examples for MicroPython + XBee. From hello world to sending min/max heartbeat data, Rob Faludi compiled fifteen great examples for XBee powered by MicroPython. Simple programs can make a big difference! An XBee running small amounts of code can perform some pretty important tasks. Cryptic readings can be transformed into useful data.
Hello World Example: Teaches how to upload code to Digi XBee3. Sense, Transform and Send a Value: Shows how to take a temperature reading and send it as a text message. Once you have set up the Digi XBee3 hardware, hooked up the TMP36 temperature sensor, connected it to the configuration software, and opened the MicroPython terminal in XCTU. I'm currently building a wireless Network using two XBee3 ZigBee Rf Modules from Digi International. These Modules have their own MC's attached and run Micropython on them. I'm able to send data between the XBee's so all the ZigBee paramters (Adressing, Security,..) are configured correctly Does XBee3 device need to be in REPL (AP=4) mode to transmit / receive stuffs answered Aug 13, 2020 in MicroPython by annacarter478 New to the Community ( 1 point) xbee3 Introduction This details an example of interfacing Amphenol's Telaire T9602-3-D-1 Humidity/Temperature sensor to Digi's XBee3 intelligent Zigbee wireless module. The project uses the T9602 sensor connected over I2C to Digi's Xbee 3 Zigbee wireless module mounted in their Grove development board. A Micropython script running on the Xbee3 reads active I2C addresses and communicates with.
In our first post in the MicroPython programming for the edge series, we talked about how to collect sensor readings and make sense of them using the Digi XBee3 Cellular LTE-M Kit, as well as Digi's free configuration software, XCTU, and some simple MicroPython code.Welcome to Part 2 of this series. The edge intelligence provided in Digi's XBee3 line of embedded RF modules makes sending. Fortunately, XCTU offers a MicroPython Terminal in its Tools menu! To start, connect the XBee3 Thing Plus to your computer using a USB micro-B cable. If you are on Windows, open the Device Manager and find out which COM port your XBee3 Thing Plus is associated with (for example, COM5)

Communicate with XBee devices. The XBee Python Library provides the ability to communicate with remote nodes in the network, IoT devices and other interfaces of the local device. The communication between XBee devices in a network involves the transmission and reception of data . So, I would like to ask, how can I program with threads in the MicroPython environment of the XBee3? Shall I install the Xbee-Python Library (by the command: pip install digi-xbee)

Enable the main.py micropython code to auto-start when the board powers up. If you've made any changes, don't forget to write your changes to the Xbee3 by pressing the following button: Step 2: Program the Xbee3 via XCTU. Next, we will upload the micropython files to the Xbee3. Open, the File System Manager Importing your own modules using MicroPython uses very similar techniques to importing modules with CPython. This page will try to cover the quirks and give some examples. CPython looks for modules using sys.path. MicroPython also looks for modules using sys.path, however, sys.path is initialized a little differently than it is in CPython.

Post. by manos » Mon Nov 30, 2020 12:46 pm. Ok, so in that case you install xbee-python library in the host pc. Then you somehow connect xbee with the host pc and without accessing the MicroPython environment of the xbee, you manage the xbee to work as a modem (in the example you mentioned) from the MicroPython. I2C is a two-wire protocol for communicating between devices. At the physical level it consists of 2 wires: SCL and SDA, the clock and data lines respectively. I2C objects are created attached to a specific bus. They can be initialised when created, or initialised later on. Printing the I2C object gives you information about its configuration Re: MCP23017 16-bit IO Expander. While creating the driver, I came up with 3 interfaces and I was going pick the most useful and maybe retire the others, or make alternate versions, so you can pick the one that works best for your needs. 1. The list interface, where each item represents a pin and has methods for reading input/setting output
I am using PyCharm version 2019.1.3 and Xbee plugin Version 1.0.1 (June 2019).

In this guide, you'll learn how to use the 0.96 inch SSD1306 OLED display with an ESP32 or ESP8266 using MicroPython firmware. As an example, we'll show you how to display a simple 'Hello, World!' message. Later, we'll also show you how to use other useful functions to interact with the OLED display It's also possible to make custom tests outside this tests folder, which would be recommended for a custom port. For example, add the following code in a file print.py in the tests/unix/ subdirectory: def print_one(): print(1) print_one() If you run your tests, this test should appear in the test output: $ cd ports/unix $ make tests skip unix.

We can use this, for example, to dim an LED or control the speed of a motor. To learn more about PWM, see this tutorial. In this example, we are going to create a simple LED animation that occurs as long as a button is held down. Hardware Connections. Connect an LED and a button to the XBee3 Thing Plus as per the following diagram I'd like to connect a CPU to the XBee3 and have it serve up a web page to the Internet. I see that PicoWeb is a web server based on MicroPython so I think what I'm asking might be possible. I'm thinking can create the HTML web page on the CPU, or feed data to the XBee3 and have it create the web page. Haven't got that far yet
I'm using MicroPython on an Xbee3-24 and it has no math module internally. I need to calculate sin, cos and arctan values. How can I use trigonometric functions without using the math module Sleeping the radio module will save energy, battery life and therefore also save money (Sleep Modes category). MicroPython scripts allow intelligent decision making to occur onboard the XBee3 module, if you launch them automatically (MicroPython Options, PS MicroPython Autostart).
