Texas Instruments introduced the affordable 16-bit MSP430 MCU Value Line to meet the changing market dynamics and requirements faced by typical low-cost 8-bit MCU developers. Taking the next step in providing a low-cost solution to the shortcomings of 8-bit MCUs, TI created the MSP430 MCU Value Line LaunchPad development kit to jump start application designs and provide a low-cost tool for developers of all experience levels. This overview will provide an introduction to the features and functionality of LaunchPad as well as everything included in the $4.30 kit.As the number of competitors grow and the time for taking products to market shrinks, the microcontroller (MCU) industry is being stretched by two opposing, but equally strong vectors. The growing demand for higher performance and ultra-low power functionality is matched only by an aggressive need for lower and lower price points. This is especially clear in low-cost applications that utilize 8-bit MCUs. To increase performance without breaking the bank, developers of low-cost 8-bit MCUs must migrate to higher performance 16-bit MCUs that are available at affordable price points.In high volume and quick turnover markets such as consumer and personal electronics, the need for a highly differentiated MCU, while maintaining aggressive price points, is a constant struggle. For instance, the market for 3D glasses has exploded in the recent months, both on the big and small screen. As this market trend moves up and to the right, developers are hard at work in creating technological solutions that provide a unique and immersive experience while remaining affordable. By providing more affordable solutions, developers hope to minimize the risks and barriers associated with new and fast moving markets.For many, this barrier to success is prohibited by a limited MCU core. Many developers of 8-bit MCUs have completely exhausted the full capabilities of their MCU due to limited data throughput and inefficient interfacing with higher resolution analog and digital peripherals. To enable increased functionality and improve feature sets of existing projects, developers must migrate to higher performance 16-bit MCUs.The MSP430 MCU Value Line series provides a migration path for many of these constrained 8-bit MCU developers. At no additional cost, the affordable MSP430 MCU Value Line devices offer a 16-bit architecture, higher precision timers and improved peripheral integration and interfacing, enabling improved performance and lower power consumption. The implementation of 16-bit MCUs enable up to 10 times improved performance and 10 times lower power when compared to many low-cost 8-bit applications. Currently, the MSP430 MCU Value Line series offers 27 ultra-low power 16-bit devices that offer varying levels of analog integration, communication modules and package types. At 100K unit volumes, MSP430 MCU Value Line devices start at just $0.25 USD, ensuring that developers do not have to sacrifice price for improved performance. Additionally, the MSP430 MCU Value Line series will continue to grow to more than 100 devices through the second half of 2011.This roadmap will introduce higher memory sizes, more package options and additional integrated analog and digital peripherals.To make the transition from 8- to 16-bit MCUs more seamless, Texas Instruments (TI) listened to the requirements of developers and created the new MSP430 MCU Value Line LaunchPad development kit. Furthering the commitment to add performance and value to MCU designs with the MSP430 MCU Value Line, TI introduced LaunchPad to lower the barrier of entry for developers new to 16-bit architectures, or those new to MCU design, in general. The LaunchPad kit is TIs simple, yet thorough, introduction to 16-bit MCU development, offering all of the hardware and software a developer needs to get started for just $4.30 USD. Within minutes of opening the LaunchPad kit, users can begin interfacing with pushbuttons, LEDs and the on-chip peripherals of the MSP430 MCU Value Line devices. See Figure 1 below: Figure 1For just $4.30, the LaunchPad kit includes a development board with an integrated USB-powered flash emulation tool for programming and debugging any of the existing MSP430 MCU Value Line devices. Any MSP430G2xx MCU in a DIP package can be dropped into the DIP target socket of LaunchPad, which allows easy evaluation of any MSP430 MCU Value Line device. The flexible target socket allows developers to remove their freshly programmed and debugged MSP430G2xx MCU to be plugged into a custom breadboard or PCB so that customers are not constrained to the form factor of the LaunchPad board. Alternatively, developers can use LaunchPad as a standalone system, by leaving the MSP430G2xx device plugged into the board to leverage on-board and programmable push buttons and LEDs. Additionally, every pin of the MSP430G2xx device is fully accessible, allowing easy interfacing of external components or custom daughter cards.Also provided in the kit are free, downloadable software compilers and debuggers including TIs own eclipse-based Code Composer Studio version 4 and IAR Embedded Workbench Kickstart. These independent development environments (IDEs) are full featured and are completely compatible with LaunchPad and the MSP430 MCU Value Line devices available today. This complements the hardware features of the LaunchPad board by providing a complete software component as well. Using either IDE, users can then leverage MSP430 MCU code examples, open source projects and other free online resources, which can be accessed on LaunchPads Wiki page, /launchpadwiki.The unlimited access to the LaunchPad Wiki promotes collaboration and simple sharing of solutions and ideas, making LaunchPad a complete development environment. This active and growing online community supplements the hardware and software components of the LaunchPad package and provides instant support, projects and helpful hints that will be shared through the Wiki pages and E2E forums.To fully benefit from 16-bit architecture and ultra-low power performance, the MSP430 MCU Value Line series and LaunchPad development kit offers a complete and simple introduction to quicken developers time to market. By providing 16-bit performance at 8-bit price points, and complete development tools for just $4.30, TI would like to welcome both new and experienced users to the world of high performance and affordable MCU development.Figure 2. $4.30 LaunchPad kit offers the hardware and software needed to start developing applications, and is backed by an active online community to quicken time to market.MSP430价值链LaunchPad开发工具包引言随着应用程序的持续发展,8位微控制器难以满足日益增产的需求更高的性能和低功耗的支持不断变化的产品设计。德克萨斯仪器公司推出的可负担得起的16位MSP430微程序控制器价值链，用以满足不断变化的市场动态和典型的低成本8位微程序控制器开发人员的需求。随后，采取了提供一个低成本的解决方案用以弥补 8位微程序控制器的不足，德克萨斯仪器公司创建了MSP430微程序控制器价值链LaunchPad开发工具包来跳跃式启动应用程序的设计并且为所有经验水平的开发人员提供了一个低成本的工具。本文将提供一个对LaunchPad及其包含所有的售价4.30美元的工具包的特性和功能的介绍。随着竞争对手的数量的增长以及把产品投入市场的时间的收缩，微程序控制器（MCU）行业被两种对立的但却同等强大的Vector总线设计以及检测工具所延伸。正在日益增长着的更高的性能和超低的功率需求的功能仅仅能被一个越来越低的价格点的积极需要所匹配。这低成本的应用显然需要利用8位微程序控制器来实现。然而，为了能够在提高性能的同时却又不至于耗尽所有的资源，开发人员的低成本8位微程序控制器必须在开发人员担负得起的价格点上迁移到更高性能的16位微程序控制器才行。在诸如消费者和个人电子这些类别的高容量并且快速周转的市场，如果要维持一个有侵略性的价格点，对于要满足一个高度差异化的微程序控制器的需求是一个持续的挣扎的过程。例如，在最近几个月里，不论是针对大屏幕抑或小屏幕，3D立体眼镜的市场都在不断地激增。当这个市场的趋势向上并且向右移动的时候，开发人员就很难创造出既能提供一个独特并且沉浸式的体验，同时又能保持使开发人员担负得起的价位的技术解决的方案来。通过提供更多的使开发人员担负得起的解决方案，开发人员希望能够减少有关新的以及快速变化的市场的风险以及障碍。对于许多人来说，这个成功的故障是由一个有限的单片机为核心的禁止。许多8位微程序控制器的开发人员们由于受到有限的数据吞吐量和低效率的接口技术同时又伴随较高的分辨率的模拟以及数字外围设备，已经完全地耗尽了他们的微程序控制器相关的全部的功能。为了能够在增加功能的同时提高现有项目的特征集，开发人员必须迁移到更高的性能的16位微程序控制器上来。MSP430微程序控制器价值链系列为很多这些受束缚的8位微程序控制器的开发人员提供了一个可以迁移的路径。在不增加成本的情况下，能够令开发人员担负得起的MSP430微程序控制器价值链装置提供了一个16位的架构，拥有更高精度的定时器以及改良的外围集成以及接口技术，能够改进其性能并且达到更低的能耗。16位微程序控制器的实现与许多低成本的8位应用程序相比，能够提升10倍的改良性能以及10倍的低功耗。目前，MSP430微程序控制器价值链系列提供了27超低功耗16位的装置，提供了不同级别的模拟集成、通信模块以及程序包的类型。在100K的储存单元条件下，MSP430微程序控制器价值链装置初始售价仅仅标为0.25美元，确保了开发人员不需要以牺牲价格为代价来提高性能。此外，MSP430微程序控制器价值链系列将继续地增长，在2011年的下半年将会拥有超过100台的设备。这个路线图将引入更高的内存大小、更多程序包的选项以及额外的集成模拟与数字外围设备。为了能够更加无缝的将8位的微程序控制器过渡成为16位的微程序控制器，德克萨斯仪器公司（TI）听取了开发商的需求并且创建了新的MSP430微程序控制器价值链LaunchPad开发工具包。进一步承诺了添加性能并且承诺了重视微程序控制器设计以及MSP430微程序控制器价值链，总而言之，德科萨斯仪器公司为新使用16位架构的开发人员以及那些新使用微程序控制器来设计的开发人员采用了LaunchPad用以降低入门的阻碍。LaunchPad开发工具包是德州仪器公司一个简单却又周密的16位微程序控制器的发展介绍，提供了所有的一个开发人员开始时所需要的硬件以及软件并且仅仅需要花费4.30美元而已。仅仅需要几分钟的时间即能够打开LaunchPad开发工具包，用户即可以通过MSP430微程序控制器价值链装置的按钮、发光二极管以及芯片上的外部设备开始界面连接。见下面的图1：图1仅售价为4.30美元，LaunchPad开发工具包包括了有一个集成的USB供电闪存的仿真工具的一个开发板，用于编程以及调试任何现有的MSP430微程序控制器价值链装置。任何MSP430G2xx微程序控制器在双列直插式组装下都可以降低至LaunchPad的双列直插式目标插座，允许简单的评估任何
