Since version 16.1, Dynamic Web TWAIN (DWT) has added a remote scan feature. If there is a device running a background scanning service (Dynamsoft Service), other devices can access it via an Intranet to use scanners connected to that device, which makes it convenient to use ...

If you want to build a cross-platform GUI app with Python and Qt, you can either use PyQt or PySide. Both of them are Qt bindings for Python. The main difference is the license: PyQt5 is released under GPL or commercial, whereas PySide2 is released under LGPL. Since PySide2 i ...

I recently purchased a Raspberry Pi 4 (4GB model) and an I2C OLED display module. In this article, I will share how to implement a C/C++ barcode reader project on Raspberry Pi 4 from scratch.

LEGO Wedo 2.0 is a good start for learning robotics. I created a simple GUI app controlling the LEGO motor using Python. In this article, I will share my experience in how to select the development environment and how to build the Python app.

If you want to use Raspberry Pi as an economical way of detecting barcodes, you can take account for Dynamsoft Barcode Reader SDK. As a business software, Dynamsoft Barcode Reader SDK is designed for overcoming a variety of complicated scenarios with sophisticated algorithms ...

Dynamsoft finally released Barcode Reader SDK v5.2 for Raspberry Pi. It is time to make an update. In this post, I will show you how to install the SDK, as well as how to write a simple Raspberry Pi barcode app using C/C++ and Python.

For the past week, I was looking for a live streaming solution to broadcast video from a USB webcam that connects to Raspberry Pi. This post will help you set up a live streaming server on Raspberry Pi step by step.

Raspbian is a free operating system based on Debian. It is the recommended operating system for Raspberry Pi. If you do not have a Raspberry Pi, you can experience Raspbian by running the OS image in the emulator - QEMU. In this article, I want to share how to resize the Rasp ...

I have been playing Pi Emulator for a while. It is time to get my hands dirty on the real Pi device. In this post, I would share how to build my first C/C++ barcode reader application on Raspberry Pi.

Raspberry Pi has been widely used in industrial environments. For instance, you can make a barcode scanner with Raspberry Pi and camera. This article will be useful for developers who want to create Node.js barcode reader applications for IoT devices. I will share how to use ...

Dynamic Web TWAIN Linux Edition is a web-based document scanning SDK based on SANE. It consists of a native scanning service, which communicates with the scanner driver, and a JavaScript scanner library. With a few lines of JavaScript code, you can quickly build robust web sc ...

Dynamic Web TWAIN for Raspberry Pi is on Dynamsoft Labs now. No matter whether you are a Dynamic Web TWAIN user or not, if you want to build a document scanning and management system with low cost, you should experience this edition. Build a smart and wireless scanner with a ...

Previously, I wrote an article Raspberry Pi Barcode Scanner with Webcam and Python illustrating how to build a simple barcode scanner using Dynamsoft Barcode Reader SDK and OpenCV from scratch. The method decodeFile() was used for detecting barcodes from an image file. To use ...

For the past few months, I have been learning Raspberry Pi. In this post, I will collect all relevant resources together in order to help readers build barcode applications on Raspberry Pi with Dynamsoft Barcode SDK.

Previously, I shared two articles demonstrating how to build a Raspberry Pi barcode scanner in C/C++ with Dynamsoft Barcode Reader SDK, and how to optimize the code with thread. The hardware I used only includes Raspberry Pi 2 and Webcam. Now it is time to have fun with GPIO ...

Although we have successfully ported Dynamsoft Barcode Reader SDK to Raspberry Pi, the performance is not as good as I expected. In my previous article, I demonstrated how to integrate the SDK into a barcode scanner application, in which the detection code works with webcam f ...
