This Section covers the design of power transformers used in buck-derived topologies: forward converter, bridge, half-bridge, and full-wave centertap. Flyback transformers (actually coupled inductors) are covered in a later Section. For more specialized applications, the principles discussed herein will generally apply.

本手冊介紹了 32 位基于 ARM 微控制器 STM32F101xx 與 STM32F103xx 的固件函數(shù)庫。該函數(shù)庫是一個固件函數(shù)包，它由程序、數(shù)據(jù)結(jié)構(gòu)和宏組成，包括了微控制器所有外設(shè)的性能特征。該函數(shù)庫還包括每一個外設(shè)的驅(qū)動描述和應(yīng)用實(shí)例。通過使用本固件函數(shù)庫，無需深入掌握細(xì)節(jié)，用戶也可以輕松應(yīng)用每一個外設(shè)。因此，使用本固態(tài)函數(shù)庫可以大大減少用戶的程序編寫時間，進(jìn)而降低開發(fā)成本。每個外設(shè)驅(qū)動都由一組函數(shù)組成，這組函數(shù)覆蓋了該外設(shè)所有功能。每個器件的開發(fā)都由一個通用 API(application programming interface 應(yīng)用編程界面)驅(qū)動， API 對該驅(qū)動程序的結(jié)構(gòu)，函數(shù)和參數(shù)名稱都進(jìn)行了標(biāo)準(zhǔn)化。 所有的驅(qū)動源代碼都符合“Strict ANSI-C”標(biāo)準(zhǔn)（項(xiàng)目于范例文件符合擴(kuò)充 ANSI-C 標(biāo)準(zhǔn)）。我們已經(jīng)把驅(qū)動源代碼文檔化，他們同時兼容 MISRA-C 2004 標(biāo)準(zhǔn)（根據(jù)需要，我們可以提供兼容矩陣）。由于整個固態(tài)函數(shù)庫按照“Strict ANSI-C”標(biāo)準(zhǔn)編寫，它不受不同開發(fā)環(huán)境的影響。僅對話啟動文件取決于開發(fā)環(huán)境。該固態(tài)函數(shù)庫通過校驗(yàn)所有庫函數(shù)的輸入值來實(shí)現(xiàn)實(shí)時錯誤檢測。該動態(tài)校驗(yàn)提高了軟件的魯棒性。實(shí)時檢測適合于用戶應(yīng)用程序的開發(fā)和調(diào)試。但這會增加了成本，可以在最終應(yīng)用程序代碼中移去，以優(yōu)化代碼大小和執(zhí)行速度。想要了解更多細(xì)節(jié)，請參閱 Section 2.5。 因?yàn)樵摴碳焓峭ㄓ玫?，并且包括了所有外設(shè)的功能，所以應(yīng)用程序代碼的大小和執(zhí)行速度可能不是最優(yōu)的。對大多數(shù)應(yīng)用程序來說，用戶可以直接使用之，對于那些在代碼大小和執(zhí)行速度方面有嚴(yán)格要求的應(yīng)用程序，該固件庫驅(qū)動程序可以作為如何設(shè)置外設(shè)的一份參考資料，根據(jù)實(shí)際需求對其進(jìn)行調(diào)整。

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
