MDK-Middleware

The MDK-Middleware software pack contains components for IPv4 and IPv6 networking, USB Host and Device communication, as well as file system for data storage. It is restricted for commercial free-of-charge usage with Arm-based devices.

The MDK-Middleware can be used by any user application. It is used by the Synchronous Data Streaming Framework to save data recorded from sensors. IoT Connectors can use the Network component to connect to the Internet.

MDK-Middleware uses a CMSIS-RTOS2-based real-time operating system for task scheduling, for example Keil RTX5 or CMSIS-FreeRTOS.

The Network component uses the Arm Mbed TLS stack to secure the TCP/IP communication. CMSIS-Drivers are a required for the components to work with the underlying hardware.

The CMSIS-Compiler and CMSIS-View components can display events and static information from all MDK-Middleware components.

The software components that are part of this CMSIS-Pack are:

• File System Component: create, save, read, and modify files in storage devices such as RAM, Flash, SD/SDHC/MMC memory cards, or USB memory devices.
• Network Component: services, protocol sockets, and physical communication interfaces for creating networking applications. It supports both, IPv4 and IPv6.
• USB Component: create USB Device and USB Host applications with standard USB device classes.

Note:
Each component is configurable for a wide range of applications and requires the driver interface as described by the CMSIS-Driver standard. Check with your silicon vendor about the availability of CMSIS-Drivers for your selected microcontroller device.

Availability

The MDK-Middleware is available free-of-charge to all users of Arm Cortex-M-based processors. It does not require a specific toolchain or IDE license and can be built with major toolchains, such as Arm Compiler 6, GCC, and LLVM.
