emWeb

SEGGER emWeb is a compact embedded web server that enables customers to provide browser-based user interfaces for embedded devices. It allows users to configure, monitor, and control a device from PCs, tablets, or smartphones without installing dedicated client software. emWeb supports static and dynamic web pages as well as technologies such as HTML, JavaScript, AJAX, Server-Sent Events (SSE), REST, forms, and CGI-based dynamic content. Optional WebSocket support enables interactive, bidirectional communication.

Key advantages include a small memory footprint, high performance, platform independence, and flexible UI design. Multiple simultaneous connections and authentication are supported, while efficient buffer handling minimizes RAM requirements. Web content can be stored using the included read-only file system or another file system. Because the interface runs in a standard browser, one web-based UI can serve different host operating systems and device types, reducing development and maintenance effort.

Integration into an existing development environment is flexible. emWeb is optimized for SEGGER emNet, but can also operate with other RFC-compliant TCP/IP stacks providing socket functionality. The web server runs as a task/thread in a multitasking environment. SEGGER supplies ready-to-use examples for embedded targets and Windows, including IPv4/IPv6 and secure SSL configurations, which can be adapted to existing projects. Web pages can also be converted into C data for direct integration into firmware. With SEGGER’s USB technologies, emWeb can additionally provide browser-based interfaces to USB-connected products.

emMQTT

SEGGER emMQTT is a lightweight MQTT client library that enables embedded devices to exchange data efficiently with IoT platforms, cloud services, and other connected systems using the publish/subscribe model. It supports MQTT versions 3.1.1 and 5.0 and can publish sensor data, device status, events, or telemetry and subscribe to commands and configuration updates. Features such as Quality of Service (QoS), retained messages, and Last Will messages support reliable communication and device monitoring.

Key advantages include a very small memory footprint, low communication overhead, scalability, and broad compatibility. emMQTT is optimized for resource-constrained microcontrollers and works with standards-compliant MQTT brokers, whether deployed locally or in the cloud. Its asynchronous publish/subscribe architecture decouples devices from backend applications, making it well suited for large IoT and M2M systems. Secure MQTT over TLS can be implemented in combination with SEGGER emSSL.

Integration into an existing development environment is straightforward. emMQTT uses a socket-based interface and is independent of the underlying TCP/IP stack, so it can operate with SEGGER emNet or any third-party IP stack providing standard sockets. The software can be delivered as source code and incorporated into existing firmware projects. SEGGER also provides a ready-to-use PC client application for testing broker connections, subscriptions, and publishing before transferring the implementation to the embedded target. This allows teams to retain their existing MCU, network stack, toolchain, and software architecture while adding standardized MQTT connectivity.nd allows emUSB-C PD to be incorporated into existing embedded firmware architectures and ANSI C development workflows.

emDropbox

SEGGER emDropbox is a compact software library that enables embedded applications to securely access and exchange files through Dropbox. Devices can upload and download files, list directory contents, rename or delete files, and use Dropbox as an intermediary between devices in the field and a central host system. Typical applications include distributing firmware updates and configuration files to remote devices or collecting log files and measurement data from them. Because files are exchanged through cloud storage, the embedded device and central host do not need to be online simultaneously.

Key advantages include simple deployment, secure communication, a small memory footprint, and hardware independence. emDropbox uses the official Dropbox API v2 and TLS-encrypted communication. Its modular architecture ensures that only required functionality is linked into the application. Written in ANSI C, it is designed to run efficiently even on resource-constrained single-chip microcontrollers.

Integration into an existing development environment is straightforward. emDropbox is available as source code and includes configuration files, documentation, and sample applications for embedded targets and Windows. Developers add the required source files and include paths to their existing project and can use SEGGER’s sample “Start” projects as integration references. emDropbox builds on SEGGER’s IoT Toolkit and emSSL and can use emNet or another TCP/IP stack that provides standard socket functionality. This allows teams to retain their existing MCU, compiler, IDE, and network architecture while adding secure Dropbox-based file exchange.
