This manual documents the microcontroller profile of version 7 of the ARM? Architecture, the ARMv7-M architecture profile. For short definitions of all the ARMv7 profiles see About the ARMv7 architecture, and architecture profiles on page A1-20.ARMv7 is documented as a set of architecture profiles. The profiles are defined as follows: ARMv7-A The application profile for systems supporting the ARM and Thumb instruction sets, and requiring virtual address support in the memory management model. ARMv7-R The realtime profile for systems supporting the ARM and Thumb instruction sets, and requiring physical address only support in the memory management model ARMv7-M The microcontroller profile for systems supporting only the Thumb instruction set, and where overall size and deterministic operation for an implementation are more important than absolute performance. While profiles were formally introduced with the ARMv7 development, the A-profile and R-profile have implicitly existed in earlier versions, associated with the Virtual Memory System Architecture (VMSA) and Protected Memory System Architecture (PMSA) respectively.

In this presentation, we will look at what the Serial Peripheral Interface, otherwise known as the SPI, is. and how it is used to communicate data to and from the PICmicro microcontroller.SPl is frequently used when few 1/O lines are available, but communication between two or more devices must be fast and easy to implement.In this presentation, we will discuss the following topics: We will first cover an Overview of SPI This section of the tutorial will introduce you to SPI and its concepts.Next, we will examine the use of SPI on the PICmicro MCU.The details of how SPI is implemented on a PICmicro device will be examined.Then, a Code Walkthrough will be given.The walkthough will explore code for both an SPI Master and SPI Slave. The example will have the Master generate data for sending to the slave.Finally, there will be a few resources given at the end of the presentation. These resources will allow you to explore in more detail the SPI interface

說明:原文(英語)來自Freescale Semiconductor,Inc.的應用文檔,作者,T.C.Lun,Applications Engineering,microcontroller Division,Hong Kong.文檔分為下列幾個部分:PART 1 觀EMC PART 2器件的選擇及電路的設計PART 3印刷電路板layout技術附錄A EMC術語表附錄B 抗干擾測量標準第一部分 EMI和EMC縱覽:在現代電子設計中EMI是一個主要的問題。為抗干擾,設計者嬰么除掉干擾源,要么保護受影響的電路,最終的目的都是為了達到電磁兼容的目的僅僅達到電磁兼容也許還不夠。雖然電路工作在板級,但它有可能對系統的共他部件輻射噪音、干擾,從而引起系統級的問題。此外,系統毅或者設備級的EMC不得不滿足某些輻射標準,以便不影響其他設備。許多發達國家在電子產品上有非常嚴格的EMC標準。為了達到這些要求,設計者必須考慮從板極開始的EMI抑制。一個簡單的EMI模型包含三個元素,如圖1所示:1.EMI源2.耦合路徑3.感應體

本書屬于8051進階級書籍,適合對單片機已經有一些經驗的讀者,或橫跨軟硬件的工程師閱讀。我們希望您在閱讀本書時,已經對8051的結構與程序有基本的認識,例如SFR、bit addressable、SBUF等等。本書共分成三大部分:第一部分是應用研究篇,介紹8051單片機的諸多設計理念與硬件保護手段。想要以子之矛攻子之盾,在這里有第一手的解答。我們也提到與硬件保護始終對立的逆向工程與8051之間的關系。最后還有一章專門提到8051的優勢與缺憾。8051當初被人稱道的功能至今被貶為重大瑕疵,為何如此?請看我們的深入分析。第二部分是介紹以FLAG51為主體的燒錄器,包括Atmel Flash microcontroller的燒錄、EPROM的燒錄以及EPROM的燒錄等,我們很樂意地公布這些燒錄程序,而且是100%的源代碼公布。以前我們徹底研究別人的程序為的是理解當初設計者的理念。今天我們公布程序內容,歡迎您來研究我們寫的程序,如果您是用心的讀者絕對可以從中獲得更多的啟示。第三部分是歷年來我們接觸到設計項目的心得以及我們對一些問題的看法。更多相關內容已全部上傳:8051單片機徹底研究-基礎篇:http://dl.21ic.com/download/8051-330965.html 8051單片機徹底研究-經驗篇:http://dl.21ic.com/download/8051-330966.html 8051單片機徹底研究-入門篇:http://dl.21ic.com/download/8051-330967.html 8051單片機徹底研究-實習篇:http://dl.21ic.com/download/8051-330969.html 8051單片機C語言軟件設計的藝術:http://dl.21ic.com/download/8051-330970.html
