光学冷加工倒角机的设计 伺服电机+LCD显示

51交通灯设计用74LS273作为输出口，带汇编程序，电路图。-51 traffic lights designed for use 74LS273 as the output port with assembler, circuit diagrams.

此文件包括各种编码转换程序，比如：二进制到BCD 码转换、二进制到ASCII码转换-This document includes a variety of encoding conversion process, such as: binary to BCD code conversion, binary to ASCII code conversion

此源代码是MSC51项目。这是一个具有自动递增功能的定时器，如果出现电源故障，可以将最后一次计数保存到at89s8254的片上闪存eeprom中。本方案采用七段式液晶显示器代替液晶显示模块。

PIC12F629写的另一个LED变化程序(慢慢从暗到最亮,用时三秒-->维持最亮四秒-->慢慢从最亮变暗,用时三秒-->维持暗灭两秒, 周而复始.-PIC12F629 write another LED changes (slowly from the dark into the light, in the opening three seconds--

The programm introduce how to choose points to create line_circle. -The programm introduce how to choose points to create line_circle.

常用EEPROM芯片的读写操作，51单片机控制电路，实验时要用74LS373一片，AT28C16一片，AT28C17一片，电路十分简单，根据实际电路联接情况，自行确定存储地址，最后别忘了还要8个LED和470欧姆电阻.-EEPROM chip used to read and write operations, 51 MCU control circuit, experiment, use 74LS373 1, AT28C16 1, AT28C17 1, the circuit is very simple, based on the actual situation of the circuit connectivity, self-determined memory addresses, finally do not forget to also 8 LED and 470 ohm resistors.

综合运用8259A,8253,8255A三个接口芯片， 编程使六个交通灯，按交通灯变化规律，循环点亮或熄灭。

走马灯（灯光变幻）程序 内容：用DIP的8位开关控制走马灯的花样，用SW3控制走马灯的起/停 运行步骤:1.按下一次开关SW3,开始灯光变幻,再按下一次则停止 可重复进行 * 2.按下SW3后，拨动不同的数码开关DIP,就会出现不同的灯光变幻 * 3.按下"q"或者"Q",退出 -Lantern (lighting changes) program elements: eight with DIP switch control of the pattern lantern, lantern used to control the effect SW3/stop running these steps: 1. Pressing a switch SW3, the beginning of the light changes, and then press the first stop can repeated* 2. SW3 pressed, the Touch different digital switch DIP, there will be changes in different lights* 3. press " q" or " Q" , from the

计时程序,对8253进行分频,使用二个计数器,使第二个计数器的OUT作为中断源,送到8259产生中断,在LED上显示时间-time procedures for the 8,253-frequency, the use of two counters, so that a second counter OUT interrupted as a source to have interrupted 8259, the time shown on the LED
