LPC2378 Schematic,with hardware

scaling triangle using scaling transformation algorithm

4X4点阵键盘+1602液晶显示做的计算器（AVR单片机）(4X4 matrix keyboard 1602 LCD calculator to do (AVR microcontroller))

基于430的DC_DC变化，采用PID控制，调节PWM的输出占公比，从而反馈调节输出电压(Based on 430 DC_DC change, using PID control, adjust the PWM output accounted common ratio, thus regulating the output voltage feedback)

硬件电路比较简单，3个LED指示灯，5个按键控制上下左右及暂停，LCD显示。总共有20关。设计用到了逻辑门控制电路。(The hardware circuit is simple, 3 LED lights, 5 key control above and below and suspension, LCD display. A total of 20 customs. The design used in the logic gate control circuit. )

这是一个51单片机小程序，功能是实现跑马表，只有三位。(This is a small program the microcontroller 51, the table function is to achieve the Happy Valley, only three.)

利用ULN2003A进行驱动，产生PWM波，里边有照片，可供参考，通过本例程了解PWM 的基本原理和使用 (#include <reg52.h> unsigned char timer1 sbit PWM=P1^2 void system_Ini() { TMOD|= 0x11 //PWM TH1 = 0xfe //11.0592 TL1 = 0x33 TR1 = 1 IE =0x8A } main() { system_Ini() while(1) { if(timer1>100) timer1=0 if(timer1<30) PWM=0 else PWM=1 } )

51单片机控制12864液晶，适合初学者入门使用，简单方面，易于移植(51 12864 LCD, suitable for beginners to use, simple terms, easy to transplant)

本程序可以读取电离层IONEX数据，可以运行，程序流畅简洁，清楚易懂!!(The program can read the ionosphere IONEX data, you can run the program smoothly simple, clear and understandable!!)
