实现光滑、密封、非常坚固的触摸控制IC,器件的电极由一个简单的线性电阻条元件(QT411)组成，可以放在塑料或者玻璃面板的后面。三个通道与感测器件相连，信号被处理成128点的绝对位置数据，通过一个SPI串行接口输出。QT411和QT511可以透过3mm厚的面板来感测，甚至在戴着手套的情况下也能感测。-Realize smooth, sealed, very strong touch control IC, the device electrodes by a simple linear resistor element article (QT411) composition, can be put on the plastic or glass panel behind. Three channels and sensors connected pieces, the signal being processed into a 128-point absolute position data, through an SPI serial interface output. QT411 and QT511 can 3mm thick panel sensor, even in the case of gloves can also sensing.

函数信号发生器根据用途不同，有产生三种或多种波形的函数发生器，其电路中使用的器件可以是分离器件，也可以是集成器件，产生方波、正弦波、三角波的方案有多种，如先产生正弦波，根据周期性的非正弦波与正弦波所呈的某种确定的函数关系，再通过整形电路将正弦波转化为方波，经过积分电路后将其变为三角波。-Function Generator according to different purposes, there have three or more of the waveform function generator, a device used in the circuit can be separate devices, can also be integrated device, resulting in square wave, sine wave, triangle wave of the program how species, such as created in the first sine wave, according to the periodic non-sine wave and sine wave which was a function of a certain set, and then by the sine-wave shaping circuit into a square wave, after integrating circuit will turn it into a triangle wave.

DataGrid控件使用技巧 　　将数据库内容绑定至DataGrid是非常简单的，我们所要做的就是通过SQL查询来生成一个DataReader对象，将DataGrid的DataSource属性设为这个DataReader对象，然后调用DataGrid对象的DataBind()方法。剩下的事情就是将DataGrid放置到HTML中， -DataGrid control skills will use the database content to bind DataGrid is very simple, we have to do is through SQL query to generate a DataReader object to the DataGrid DataSource attribute set to the DataReader object, and then call DataGrid object DataBind () method. The remaining issues will DataGrid is placed into HTML,
