msp430单片机的仿真电路图 可以用 又简单(MSP430 MCU circuit simulation can be used and easy)

鼠标滑动截图，截图后 点击winform其它位置 则将图片黏贴到相应位置

DS 回调函数使用实例，可以参考学习11(自动检测中英文中译英英译中百度翻译 翻译结果（中 > 英）复制结果 Examples of the use of DS callback function, can refer to learning11 )

Matlab7.0，英文版的，讲的都是基础，适合初学者入门，很不错的资料。(Matlab7.0, the English version of, say are the basis of entry for beginners, very good information.)

二维情况下用ＦＤＴＤ方法模拟电磁波的传播情况，没加吸收边界条件，用Ｃ和MATLAB混合编程，信号源是高斯脉冲(Two-dimensional case with the FDTD simulation of electromagnetic wave propagation, no additional absorbing boundary condition, mixed with the C and MATLAB programming, the signal source is a Gaussian pulse)

基于STM32的OBD-CAN转换接口 只有源程序，原理图很简单自己看懂源代码就会了。(OBD-CAN conversion interface based on STM32 Only the source program, the schematic is very simple, you will understand the source code)

Delphi语言参考手册，用户非常需要，尤其对初学者非常重要。-Delphi language reference manual, users need, especially for beginners is very important.

触发器，eda.在实际的数字系统中往往包含大量的存储单元，而且经常要求他们在同一时刻同步动作，为达到这个目的，在每个存储单元电路上引入一个时钟脉冲（CLK）作为控制信号，只有当CLK到来时电路才被“触发”而动作，并根据输入信号改变输出状态。把这种在时钟信号触发时才能动作的存储单元电路称为触发器(Triggers, eda. The actual digital systems often contain a large number of memory cells, and at the same time they often require synchronized action, to achieve this purpose, the introduction of a clock pulse (CLK) in each memory cell circuit as a control signal , the arrival of the circuit only when CLK was only trigger the operation and change the output state of the input signal. The memory cell circuit that can trigger actions when the clock signal is called a flip-flop)
