"Practical UML Statecharts in C/C++, Second Edition: Event Driven Programming for Embedded Systems" (PSiCC2) is now available for pre-orders from Amazon.com and other online book sellers. The second edition is a complete re-write of the first edition and now presents a detailed design study of the new QP v4.0.

Based on the total number of views received, our article came up second of the most popular Design Articles on Embedded.com during 2007.

All QP versions and components of the new version 3.4.xx have been released under the terms of the GPL open source license as well as traditional commercial licenses (dual licensing). The Generally Available (GA) releases of QP/C, QP/C++, and QP-nano v3.4 are available for download.

Previously the software tracing component (Quantum Spy) of QP/C and QP/C++, as well as the preemptive run-to-completion kernel in QP-nano were available only for commercial licensees. Now, all software offered by Quantum Leaps, LLC is available under the same dual licensing model.

This article by Miro Samek of Quantum Leaps describes how to properly use the low-power sleep modes of various popular MCUs in the most ubiquitous foreground background architecture. The following MCUs are discussed: HC(S)08, MSP430, AVR, ARM, ARM Cortex-M3, 8051, and M16C. The presented examples span a broad range of techniques and you should be able to find the right solution for virtually any MCU in the industry.

This article is applicable to the simple, non-preemptive "vanilla" scheduler that is provided in QP.

This long, in-depth, 10-part article by Miro Samek of Quantum Leaps describes in detail how to use the GNU toolchain for ARM to build real-life embedded systems based on ARM microcontrollers.

This article demonstrates Quantum Leaps' commitment to open source and our expertise in the ARM processor. The article is the recommended reading for using QP and QP-nano ports to the ARM processor with GNU.

Quantum Leaps, LLC released today its Quantum Platform (QP) family of frameworks to the SourceForge.net code repository. The baseline code for QP/C, QP/C++, and QP-nano, as well as the extensive documentation and examples are available for download from https://sourceforge.net/projects/qpc/.

The QP-emWin integration demonstrates how to use Quantum Platform™ (QP) with embedded GUI libraries, such as emWin™ from SEGGER or µC/GUI from Micriµm.

All five state machine design patterns described in Chapter 5 of PSiCC) have been implemented with the latest QP/C, QP/C++, and QP-nano.

Quantum Platform Nano™ (QP-nano) has been released under the terms of the GPL open source license as well as traditional commercial licenses (dual licensing). The Generally Available (GA) release of QP-nano™ is available for download from the Quantum Leaps web site. More...

Quantum Platform (QP) v3.2 has been released. This version brings incremental improvements mostly to QF and QK components. The detailed change report is available in the release notes.

July issue of the ESD magazine describes the inner workings of a single-stack kernel called "Super Simple Tasker" (SST). Quantum Leaps provides an industry-strength implementation of the single-stack kernel, called Quantum Kernel (QK) that works exactly like SST and only differs in the way it is integrated with the state-machine event processor (QEP) and the state machine framework (QF). All these components are available under the GPL open source license.
