EP2C35开发板官方原理图,是altera的官方资料。是fpga电路设计的很好参考典范。...

是51单片机常用头文件定义，直接调用就可以，包括：1602液晶，12864液晶，5110屏，I2C,UART,精确延时函数，PWM调速，DS1302，DS18B20,,,,,,,(51 microcontroller used header file defines direct call can include: 1602 LCD, 12864 LCD, 5110 screen, I2C, UART, precision delay function PWM speed control, DS1302, DS18B20,,,,,)

1、ps/2键盘输入，通过led显示ascii码 2、稍等1s可以在lcd上显示输入的字符 3、其中键盘上的backspce键是用来清屏的 4、当lcd上显示满字符时，在按下按键自动清屏，从第一行显示。-1, ps/2 keyboard input, through the led display ascii code 2, wait 1s in the lcd display characters input 3, which backspce keys on the keyboard was required to settle the screen 4, when the lcd display full of characters, the press the button automatically Qing-ping, from the first line of display.
