电容在EMC设计中应用技巧, 和一些注意的问题,可以-Capacitance in the application of EMC design techniques, and some attention to the problem, you can

此示例代码需要平均为 2048年模拟测量从输入 P1.1 使用 ADC0，然后将结果打印到终端窗口通过 UART。该系统由内部 24.5 MHz 振荡器的时钟频率。定时器 2 触发每个溢出上 ADC0 转换。在完成这种转换反过来触发中断服务例程 (ISR)。ISR 平均 2048年测量，然后打印到 printf 之前通过终端值开始另一种的平均周期。模拟多路复用器选择 P1.1 作为积极 ADC0 输入。此端口被配置为模拟输入端口初始化例程中。负 ADC0 输入通过多路复用器到地面，那为单端 ADC 的输入提供了连接。

This example program shows how to configure and use the A/D Converter of the following microcontrollers: * Philips LPC 2114/2119/2124/2129/2131/2132/2138/2194 After configuring the A/D Converter, the program reads A/D channel 0 and outputs the converted value using the serial port. To run this program... 1. Select the Device (Project - Options for Target - Device) 2. Build the project (Project - Build Target) 3. Start the uVision Debugger 4. Open the Serial Window (View - Serial Window 1) 5. Click Run (F5) 6. Click on the Toolbox buttons to change input voltages A debug script (debug.ini) creates buttons that set different analog values in A/D channels. As the program runs, you will see the A/D input and output change. Other buttons create signals that generate sine wave or sawtooth patterns as analog inputs. µ Vision3 users may enable the built-in Logic Analyzer to view, measure and compare these input signals grap

arm的非向量中断通过执行IsrIRQ判断中断源，找到相应Handle***的地址。 此程序是在arm上实现向量方式中断的初始化程序-arm of the non-vector interruption through the implementation IsrIRQ judgment interrupt source, find the corresponding Handle*** address. This procedure is the arm on the way to achieve vector interrupt the initialization procedures
