Application Note 268

Creating a CMSIS Middleware Application

With the availability of more capable microcontrollers, software development for these devices has become more complex over the years. The use of real-time operating systems is rapidly becoming an industry "best practice", and integration of commercial middleware as well as the reuse of custom libraries is gaining importance for cost-efficient software engineering. Successfully combining these building blocks of a modern embedded application often poses a problem for developers. To resolve this, ARM developed the Cortex Microcontroller Software Interface Standard (CMSIS).

This application note explains, step-by-step, how to setup, debug and run a CMSIS-compliant application using the RTOS, USB and graphic display capabilities of MDK-ARM Professional development kit Version 5. A set of videos explaining these steps can be found here:.

This application note requires that version 5.14 or later of the MDK-ARM Professional development kit be installed on your PC, along with version 2.4.0 or later of the KEIL.STM32F4XX_DFP software pack. Also, ARM::CMSIS 4.3.0 and Keil::ARM_Compiler 1.0.0 Packs are required.
