12864液晶显示图像与文字的C51程序(12864 LCD image and text C51 program)

说明：  buck、boost、cuk、正激、反激等电路的matlab仿真和文字介绍，均运行正常(Matlab simulation and text introduction of buck, boost, Cuk, forward and flyback circuits are all running normally)

blcd source, it is blcd source can convert from one format to antother

利用单片机SCMAD口与热敏电阻阻简单实现测温电路及程序可直接使用。 (SCMAD mouth with the use of single-chip thermistor temperature measurementt circuit to achieve a simple and complete source code can be used directly. )

说明：  基于stm32的交通灯仿真 proteus8.9(stm32 traffic light proteus8.9)

实现计数器加法、减法、清零电路。用7448、74ls192实现，可以仿真成功，适用于初学者。(Realization counter addition, subtraction, clear circuit. By 7448,74 ls192 achieve success can be simulated, for beginners.)

EV1527发射程序，自定义发射格式及传输协议， 非常不错的程序。(EV1527 launch program, launch a custom format and transmission protocol, Very good program.)

诺基亚5110的驱动程序，主要用于单片机的开发，充当显示模块。(Nokia 5110 driver, mainly for single-chip development, act as a display module.)

A Comparison of Ladder, Series, and Shunt Type Stepped Attenuators

神经网络中的权值、阈值以及中间变量很多，但是单片机的程序区和数据区的容量都是有限的。89C52程序区为8K字节，数据区为256K字节。由于探测器受体积限制应尽量避免外扩存储器，所以在实现计算时，要将权值和阈值写成立即数形式减少资源占用。(Neural network weights, threshold and intermediate variables, but procedures for single-chip area and the volume of data are limited. 89C52 process area for 8K byte, 256K-byte data area. As the detector by the volume limit should be avoided as far as possible outside the extended memory, so in the realization of the calculation, the right to the threshold value and written in the form of an immediate reduction in the number of occupied resources.)
