單片機(jī)入門知識(shí)手冊(cè) 說到單片機(jī)，首先想到的是中央處理器（CPU），學(xué)過微型計(jì)算機(jī)的人都知道，CPU是計(jì)算機(jī)最核心的部分，它可以完成算術(shù)運(yùn)算和邏輯運(yùn)算，CPU再配上外部存儲(chǔ)器，輸入輸出單元就構(gòu)成一臺(tái)微型計(jì)算機(jī)。其實(shí)單片機(jī)可以看成一臺(tái)微型計(jì)算機(jī)，它具有CPU的功能，并且自身帶有存儲(chǔ)器，帶有輸入輸出接口（如串行UART、AD轉(zhuǎn)化、PWM控制），單片機(jī)配上一些簡(jiǎn)單的外圍電路，就可以完成智能控制或數(shù)據(jù)采集等。所以，單片機(jī)的英文名叫MCU（Micro Chip Uint），翻譯成中文是微控制單元。 單片機(jī)能干什么？通俗一點(diǎn)講，單片機(jī)只有兩個(gè)功能：一個(gè)是數(shù)據(jù)采集，另一個(gè)是控制。其實(shí)都很好理解，數(shù)據(jù)采集實(shí)際上是從外間輸入，如從AD（模數(shù)轉(zhuǎn)化）口讀入一個(gè)電壓值，從串口接收一個(gè)數(shù)據(jù)等等。控制實(shí)際上是輸出，51單片機(jī)有32個(gè)IO口，每個(gè)IO口可以驅(qū)高或驅(qū)低，單片機(jī)以此來實(shí)現(xiàn)對(duì)外間的控制。一個(gè)單片機(jī)系統(tǒng)都可以用下面這個(gè)框圖來說明：

Luminary Micro provides an analog-to-digital converter (ADC) module on some members of theStellaris microcontroller family. The hardware resolution of the ADC is 10 bits; however, due to noiseand other accuracy-diminishing factors, the true accuracy is less than 10 bits. This application noteprovides a software-based oversampling technique, resulting in an improved Effective Number OfBits (ENOB) in the conversion result. This document describes methods of oversampling an inputsignal, and the impact on precision and overall system performance.

Luminary Micro Stellaris™ microcontrollers that are equipped with an analog-to-digital converter(ADC), use an innovative sequence-based sampling architecture designed to be extremely flexible,yet easy to use. This application note describes the sampling architecture of the ADC. Sinceprogrammers can configure Stellaris microcontrollers either through the powerful StellarisFamilyDriver Library or through direct writes to the device's control registers, this application note describesboth methods. The information presented in this document is intended to complement the ADCchapter of the device datasheet, and assumes the reader has a basic understanding of howADCsfunction.

The μPSD32xx family, from ST, consists of Flash programmable system devices with a 8032 MicrocontrollerCore. Of these, the μPSD3234A and μPSD3254A are notable for having a complete implementationof the USB hardware directly on the chip, complying with the Universal Serial Bus Specification, Revision1.1.This application note describes a demonstration program that has been written for the DK3200 hardwaredemonstration kit (incorporating a μPSD3234A device). It gives the user an idea of how simple it is to workwith the device, using the HID class as a ready-made device driver for the USB connection.IN-APPLICATION-PROGRAMMING (IAP) AND IN-SYSTEM-PROGRAMMING (ISP)Since the μPSD contains two independent Flash memory arrays, the Micro Controller Unit (MCU) can executecode from one memory while erasing and programming the other. Product firmware updates in thefield can be reliably performed over any communication channel (such as CAN, Ethernet, UART, J1850)using this unique architecture. For In-Application-Programming (IAP), all code is updated through theMCU. The main advantage for the user is that the firmware can be updated remotely. The target applicationruns and takes care on its own program code and data memory.IAP is not the only method to program the firmware in μPSD devices. They can also be programmed usingIn-System-Programming (ISP). A IEEE1149.1-compliant JTAG interface is included on the μPSD. Withthis, the entire device can be rapidly programmed while soldered to the circuit board (Main Flash memory,Secondary Boot Flash memory, the PLD, and all configuration areas). This requires no MCU participation.The MCU is completely bypassed. So, the μPSD can be programmed or reprogrammed any time, anywhere, even when completely uncommitted.Both methods take place with the device in its normal hardware environment, soldered to a printed circuitboard. The IAP method cannot be used without previous use of ISP, because IAP utilizes a small amountof resident code to receive the service commands, and to perform the desired operations.

This application note shows how to write an Inter Integrated Circuit bus driver (I²C) for the Philips P90CL301micro-controller.It is not only an example of writing a driver, but it also includes a set of application interface software routines toquickly implement a complete I²C multi-master system application.For specific applications the user will have to make minimal changes in the driver program. Using the drivermeans linking modules to your application software and including a header-file into the application sourceprograms. A small example program of how to use the driver is listed.The driver supports i.a. polled or interrupt driven message handling, slave message transfers and multi-mastersystem applications. Furthermore, it is made suitable for use in conjunction with real time operating systems, likepSOS+.
