#pyserial

[yokowan]

the python package for working with serial interfaces is called "pyserial" because the name "serial" was taken by a python class serializer that never left alpha that hasn't been maintained in over 5 years and I only install the wrong one about 50 percent of the time

How to send and receive sms using gsm modem ?

Sending and receiving SMS using a GSM modem can be done in two main ways: using AT commands or through software libraries. Here's a breakdown of both methods:

1. Using AT Commands:

This method involves sending text commands ("AT commands") directly to the GSM modem to control its functions. It's a more technical approach and requires knowledge of the specific AT command set supported by your modem.

Here's a general process:

a. Connect and Configure:

Connect the modem: Connect your GSM modem to your computer via USB, serial port, or other means.

Identify the COM port: Use your computer's settings to identify the COM port assigned to the modem.

Open a terminal emulator: Open a program like PuTTY or HyperTerminal to send AT commands.

Set the baud rate: Configure the terminal emulator's baud rate to match the modem's (usually 9600).

Send basic commands: Test the connection by sending basic AT commands like "AT" or "ATE0" and verify responses.

b. Send SMS:

Compose message: Prepare your message content and ensure it's within character limits (usually 160 characters).

Use AT commands: Use specific AT commands like "AT+CMGS" to send the message.

Specify recipient: Include the recipient's phone number as part of the command.

Send the message: Send the command to initiate the SMS transmission.

c. Receive SMS:

Enable notifications: Use AT commands like "AT+CNMI" to enable the modem to notify you of incoming messages.

Handle notifications: Your terminal emulator should display notifications when messages arrive.

Read message: Use AT commands like "AT+CMGR" to read the message content and sender information.

2. Using Software Libraries:

Many libraries and software tools exist to simplify GSM modem communication. These libraries provide user-friendly functions for sending, receiving, and managing SMS messages.

Here's the general process:

Choose a library: Popular options include Gammu, SMSlib, PySerial (Python), and similar tools.

Install and configure: Follow the library's installation and configuration instructions.

Write code: Use the library's functions to send and receive SMS messages within your code.

Run the code: Execute your code to interact with the GSM modem and send/receive messages.

Making Raspberry Pi and Arduino Speak To Each Other

As part of our project requires a micro controller to do some of the functions, we need an easy way for that data to be communicated either way. The micro controller is a ATMEGA328p, which is well known for being the core of the Arduino Uno.

Serial

One standard that has been around for a while for making devices talk to each other is Serial UART. This requires 3 wires, a reference voltage (Ground), a transmit (data out), and a receive (data in). by connecting two chips from their transmit to the receive you can send data between them. you do however, need to know a few things, what speed and what voltage are two important variables (but not the only).

Different Voltages

The problem with the Raspberry Pi and the ATMEGA chip is I want the ATMEGA to be at a 5V logic, where as, the Raspberry Pi is at a 3.3V logic. If I were to connect these it is likely I would damage the Raspberry Pi. 

Logic Level Converter

This is where a Logic Level Converter comes in. It connects to the 5V logic on one side and the 3.3V logic on the other side and keeps them completely Isolated.

Code

The next challenge was making a program in python to communicate over serial so I can use the code in my final program. for this I used the PySerial Library.

Can we use serial library for python 3.5

Any help for this error will be much appreciated. To create a new search service, you can use the Azure portal, Azure PowerShell, or the Azure CLI. You need an Azure subscription and a Azure Cognitive Search service to use this package.

The python 3.5 cannot import serial which i do not know how to solve. Python 2.7, or 3.5 or later is required to use this package. If so, you do not need to install or congure anything else to use Python. I have install the pySerial-2.7 module into the python using the tutorial below:Įverything went smoothly when I used Python 2.7 as I uninstall it and migrate to python 3.5įile "/Library/Frameworks/amework/Versions/3.5/lib/python3.5/site-packages/serial/ init.py", line 21, in įile "/Library/Frameworks/amework/Versions/3.5/lib/python3.5/site-packages/serial/serialposix.py", line 58 Pythonnet supports from Python 2.6 up to Python 3.5.45 Properly Install Python on your system: 1.2Properly Installing Python There’s a good chance that you already have Python on your operating system. It will be very grateful for anyone that can solved my problem. This can be avoided by installing from the numba conda channel. Note: If you’re using a Python 3.5 environment in conda, you may run into trouble with the numba dependency. How do I copy a file How do I read (or write) binary data I cant seem to use os.read() on a pipe created with os.popen() why How do I access the serial (.

Open the Anaconda prompt and write: conda install -c conda-forge librosa. I have been trying to find a solution through the web, but none of the solutions I saw solved my problem. If you use conda/Anaconda environments, librosa can be installed from the conda-forge channel.

Then, we'll use Python to install proper libraries to read data from Arduino Uno R3. You may like to compare yours with my working program. We'll start by installing Raspbian Buster Lite in our Raspberry Pi Zero W. Arduino Uno R3 board or compatible board (you can also consider the Elegoo starter kit).micro SD card (at least 16 GB, at least class 10).Raspberry Pi Zero W (including proper power supply or a smartphone micro USB charger with at least a 3A) or newer board.Steps should also work with newer Raspberry Pi boards.

The fastest way to get access to the command line is through the Terminal app. With the second installment on affordable home automation based on Raspberry PI still to come, today I want to show how to access our Raspberry PI terminal through the serial port esto puWith the. For this purpose, we'll use Pyserial and its terminal tool. When you boot a Raspberry Pi, you start by default inside the desktop interface. In this guide, I'll show you how to connect your Raspberry Pi to a serial USB port and read its values with Python from the terminal (without a desktop environment). You can also use Raspberry Pi to dialog with some devices-like Arduino-by using a serial USB port. Raspberry Pi can be used to interface with the real world from its GPIO, for example, by controlling a stepper motor.

Python AttributeError: module object has no attribute Serial

Im adding this solution for people who make the same mistake as I did.

In most cases: rename your project file serial.py and delete serial.pyc if exists, then you can do simple import serial without attribute error.

Problem occurs when you import something when your python file name is something.py.

I accidentally installed serial (sudo python -m pip install serial) instead of pySerial (sudo python -m pip install pyserial), which lead to the same error.

If the previously mentioned solutions did not work for you, double check if you installed the correct library

Paperless Student? An Update

One of my all-time most popular posts was about being a paperless student. In this post, I'll be providing an update on my current paper use as a student now that I am back in in-person classes. It is also an update on the post I wrote last fall on the apps I use in remote college. I still try to be as paperless as possible, but unfortunately, some of my professors print stuff out for us or require us to turn in hard copies. The core products continue to be Microsoft OneNote for notes, Google Drive for files, Microsoft Lens for scanning, and PDF Expert for reading and annotating PDFs. A web application and Chrome extension that I have recently discovered is Speechify which converts text-to-speech. This post is broken into sections for each of my courses. For the full list of my current courses, click here. In a future post, I’ll update you all on my current time and task management systems as there have been some significant changes. 

CSC 220

All of our assignments are completed digitally as this is a web programming class. I have been writing code in Visual Studio Code and have been using MAMP as my local webserver. My file transfer protocol (FTP) client is Cyberduck. As for notetaking, I type up my tutorial and lecture notes in OneNote. Rather than use a textbook, we’ve been completing lots of tutorials on a website called W3Schools. 

CSC 223

Our readings and other assignments for this class have been digital so far, but we may end up sketching a few things on paper. We are learning Ruby on Rails and had to install a bunch of software to get everything up and running. The terminal I use is a Linux distribution called Ubuntu. (I also occasionally use this for CSC 220). My text editor of choice is Sublime Text. We also make use of GitHub. During class, I take handwritten notes on my iPad (in OneNote of course). My reading notes are typed up in OneNote and my reading reflections are typed up in Google Docs.

EGR 320

This class is why I can no longer claim to be a paperless student. We get hard copies of all the slide decks and worksheets and must turn in hard copies of our homework on engineering paper. We even need to print out our MATLAB code and figures. I do actually use the paper handouts, but also take some handwritten notes on my iPad while watching the pre-class videos. As for textbook notes, I type them up. Upon getting my homework turned back, I scan the pages (using Microsoft Lens) and upload them to my Google Drive. One nice thing about this class and its paper use is that the professor provided us with a nice binder and dividers to use. For now, I am using my own 1-inch binder, but I’ll probably have to transfer things to the class issue 1.5-inch binder soon as I’m running out of space. We were also given physical textbooks to use for the semester, but I prefer to read the PDF version on my iPad.

EGR 390dc

Like EGR 320, homework must be complete on engineering paper. Fortunately, I don’t need to turn in a hard copy and can simply scan my homework and then upload it to Moodle (and Google Drive for safekeeping). For lab work, we use the Arduino IDE and Spyder (installed via Anaconda) which is a Python IDE. In order to program the Arduinos with Python code, we use a library called pySerial. I do my actual lab write-ups in Google Docs. Fortunately, we were provided with a PDF textbook that I read on my iPad. Just last class we started getting paper handouts in class, but I opted to continue taking handwritten notes on my iPad. I did have to frequently add screenshots from the lecture slides as there were circuit diagrams that would have taken too long to draw neatly. Like most of my other classes, my textbook notes are typed.

ENX 100

For this class, I read and annotate the readings on my iPad in the PDF Expert app. (I first download the files from Moodle and then upload them to GoogleDrive). As for my response papers, I write them up in Google Docs. During our first lecture, I typed up a few notes in OneNote. Since we’ve only met twice, I am still figuring out my systems for this class. 

ESS 945sp

In this class, my journal and weekly papers are typed up in Google Docs. My Fitbit (and the corresponding app) have also been helpful digital tools for tracking my workouts.

ITL 205

Just like in ENX 100, I read and annotate the PDF readings in PDF Expert. Our quizzes are on paper, but we don’t get them back so it doesn’t bother me. So far, I haven’t been taking notes as I prefer to engage fully with the lecture and don’t need to remember super specific and obscure facts to be successful. I have been bringing a paper notebook just in case because the professor really doesn’t want people on electronic devices.

Stranger Arduino-Python

Se me ocurrió que estaría muy genial hacer un programa en el que si vos escribís algo hiciera como en la serie Stranger Things y se prendieran leds que correspondieran con las letras del mensaje. Al principio no pensé demasiado en como hacerlo porque sabía que no tenia tiempo para hacerlo, pero un día me acorde de cuando usamos la librería Pyserial y me di cuenta que usándola hacer lo que quería era muy fácil. Es más, también recordé que en el primer obligatorio de programación 1 ya había hecho un programa que te separaba las palabras por caracter y luego se fijaba que letra era cada uno, así que ya tenia lo que me parecía mas difícil hecho. También ya había logrado la conexión con pyserial en otro proyecto asi que eso también estaba hecho. Lo único que me llevo un poco de tiempo fue darme cuenta de como hacer que python me leyera el espacio en blanco (con un poco de búsqueda encontré una función que lo hace).

Óptimamente usaría el arduino MEGA u otro que tuviera al menos 27 pins para poder tener un led para cada letra del abecedario, pero como solo tengo un arduino UNO utilicé solo 9 leds (el UNO tiene 12 pins que podría usar pero también me faltaron cables y leds). De todas formas aunque tal vez fue más fácil de lo que esperaba me divirtió mucho este proyecto, mas que nada por el resultado y además se me ocurren muchas cosas para hacer con él. También tengo un amigo que tiene un arduino MEGA así que seguramente pueda completar el abecedario algún día de estos.

CODIGOS

Python:

#Proyecto Stranger things
