绝对好用的I2C和USBSWITCHTO232 绝对好用的I2C和USBSWITCHTO232

由于该源程序并非为单片机而编写，因此资源占用率很大，要想在C51中使用，还必须对其进行改造-because the source is not prepared for a microcontroller, the occupancy rate has great resources, in order to use the C51, we must transform its

通过实验进一步了解和掌握单片机原理的基本概念、单片机应用系统的硬件设计及调试方法-Through experiments to further understand and grasp the basic concepts of SCM principles, microcontroller applications, the hardware design and debugging method

尽量朝“单片”方向设计硬件系统。系统器件越多，器件之间相互干扰也越强，功耗也增大，也不可避免地降低了系统的稳定性。随着单片机片内集成的功能越来越强，真正的片上系统SoC已经可以实现，如ST公司新近推出的μPSD32××系列产品在一块芯片上集成了80C32核、大容量FLASH存储器、SRAM、A/D、I/O、两个串口、看门狗、上电复位电路等等。 -North Korea as the "single-chip" design direction of the hardware system. System devices more mutual interference between devices are more strong, power consumption is increased, it will inevitably reduce system stability. With MCU with on-chip integration of more powerful, the real system-on-chip SoC can achieve, such as ST"s new PSD32 x x in a series chip integrates exertion nuclear, large-capacity flash memory, SRAM, A/D, I/O, 2 serial port, watchdog, the power-on reset circuit and so on.

能够掌握单片机的管脚功能，简单了解并应用单片机作东西。-to grasp the pin MCU functions, simple to understand and use things for the MCU.

用proteus仿真实现投币赌博机，编译软件：keil C -Simulation with proteus gambling slot machine, build the software: keil C

keilC芯片选择可以看出STC中不需要包含

单片机控制122x32液晶。液晶内部芯片包含RAM（类似于显存），当然不具备2D3D加速。不过，功耗非常低，一般几个毫瓦。-SCM 122x32 LCD. LCD chip contains an internal RAM (similar to memory), of course, does not have to speed up 2D3D. However, power consumption is very low, generally a few milliwatts.

这个程序是在单片机上实现拼音输入法，采用了KeilC编译。-This process is achieved in single-chip Pinyin input method, using a compiler KeilC.
