Description: PWM控制输出电压由于该程序所需完成的功能比较简单，设计时采用了简单的前后台组织结构：后台程序（主程序）在非通讯状态时工作，完成各项数据的采集和预处理，并标准化至通讯协议所规定的格式。这一过程不停进行，随时提供最新数据；前台程序（中断服务程序）在接收到来自控制器的命令时启动。它对命令加以识别，并按要求向控制器传送相应数据或对数据进行解析执行。该程序的流程示意如图-PWM output voltage control due to the completion of the procedures required for the function of a relatively simple design, a simple organizational structure around Taiwan : background (main program) in non-state communication, complete data acquisition and pre-processing, and standardized communication protocol to the format provided. This process conducted on a continuous basis and provide the latest information; Prospects (interrupt service routine) from the receiving controller to activate the orders. It ordered to be identified, together with a request to the controller or corresponding data transmission for data analysis implementation. The indicative of processes figure

Description: 移植到MCS51的uCOS_II。
1。在文件OS_CORE.C中OSMapTbl和OSUnMapTbl数组用于查表，所以应该放在code里。
增加code关键字。UCOS_II.H和OS_CORE.C。
2。OS_CFG.H堆栈大小MaxStkSize改为900。
3。OS_CPU_C.C的InitTimer0函数增加了关于开T0中断的解释。
允许T0中断，此时EA=0(51上电缺省值)，中断还不会发生，满足在OSStart()前不产生中断的要求。
4。修改中断处理流程，以便严密监视中断嵌套情况。每个中断进入后立即进行OSIntNesting+1原语操作。
5。增加printf函数的移植，支持灵活的数据显示。支持标准或长二进制/八进制/十进制/十六进制/无符号整数，
支持字符、字符串、浮点数、百分号％。其中，浮点数在整个范围内被完全支持，统一采用科学记数法显示。

Description: 本驱动程序在linux2.6.17中测试通过。yangxing msn:lelma_yx@hotmail.com
希望对SPI操作的朋友有所帮助。
一、工作方式：
从设备：SPI为MASTER模式
S3C2410：SPI为SLAVE模式＋DMA
二、工作流程
1.S3C2410从接收：当从设备发送数据时，S3C2410利用DMA方式收数，收到指定长度的数据，则进入DMA中断，将接收的数据拷出。
2.S3C2410从发送：当S3C2410需要发送，首先由RTS请求发送，然后等待从设备应答CTS，当从设备应答CTS时，进入外部中断，启动DMA发送，发送完成，再次进入从接收状态。
三、文件位置
spi_dma_slave.c
spi_dma_slave.h
circular_buf.c
circular_buf.h
等文件存放入driver/char/目录
dma.c存放于arch/arm/mach-s3c2410/目录
dma.h存放于include/arm-asm/mach-s3c2410/目录
四、使用环境
1.arm-linux-gcc-3.4.1-the driver linux2.6.17 in which the test. Yangxing msn : lelma_yx@hotmail.com hope to operate SPI friends help. 1, mode of work : from equipment : SPI for the S3C2410 MASTER mode : SPI for SLAVE + DMA mode 2, workflow 1.S3C2410 from receiving : When sending data from the device, using DMA S3C2410 debt, the length of the designated data DMA will enter the interruption will receive unfettered access to the data. 2.S3C2410 from this : When S3C2410 need this, the first request sent by the RTS, Then wait for the response from CTS equipment, when the equipment response from CTS, access to external interrupt start DMA sent, Send completed, re-entered, from receiving state. 3. Position papers spi_dma_slave.c spi_dma_slave.h circul ar_buf.c circular_buf.h documents onto the driver / char / Contents

Description: 硬盘主引导记录程序的功能是读出自举分区的BOOT程序，并把控制转移到分区BOOT程序。整个程序流程如下：
1 将本来读入到0：7C00H处的硬盘主引导记录程序移至0：61BH处；
⑵ 顺序读入四个分区表的自举标志，以找出自举分区，若找不到，转而执行INT18H的BOOT异常执行中断程序；
⑶ 找到自举分区后，检测该分区的系统标志，若为32位FAT表或16位FAT表但支持13号中断的扩展功能，就转到执行13号中断的41号功能调用进行安装检验，检验成功，就执行42号扩展读功能调用把BOOT区程序读入到内存0：7C00H处，成功，跳到第⑸步，若读失败或系统标志为其它，就调用13号中断的读扇区功能调用把BOOT读到0：7C00H；
⑷ 用13号中断的读扇区功能时，用两种方式分别进行5次试读。第一种方式是直接从自举分区的头扇区读入BOOT程序，若读成功，但结束标志不是55AA，则改用第二种方式，又如果用第一种方式试读五次均不成功，就改用第二种方式。若两种方式试读均失败，就转到出错处理程序；
⑸ 读入BOOT区程序成功，转至0：7C00H处执行BOOT程序。 -err

Description: 本程序是一种先进的充气电缆气压自动监测系统的程序。其特点是可以对电缆线路上各点的气压值进行24小时实时监控。使管理人员可以实时掌握电缆内的气压情况，及时发现漏气隐患，从而保证通信畅通。
系统采用性能价格比较好的AK-3 型压力传感器，直接输出0～5V电压信号。电压信号的转换采用串行接口的12位A/D转换器TLC2543，精度和速度都能很好地满足系统要求。仪器的CPU采用目前低价位但技术十分成熟的AT89C51，仪器的LED数码管显示/驱动芯片采用接口简单但功能强大的HD7279。本系统提供日历时钟电路，在方便用户确定时间的同时，还可以为定时通信提供依据；在发生报警时还能向上位机提供确切的报警时间。同时系统还设计了RS-232总线的通信接口电路，每到整点就要向上位机发送各路气压值，供上位机记录分析。
本系统软件分两大部分，键盘中断和定时中断。工作流程是这样的：每50ms就要进行AD转换，尺度变换，比较是否越位，是否报警等操作，如果有按键动作，执行键盘中断程序。键盘解释在5s之内有效。
