74HC595
将每2片74595做级联,然后再将级联之后的所有时钟线与数据再并联在一起最后对每一组的锁存控制线做单独控制.(Application to do a project, the more I/O, applied to the 74,595 to do the extension, but you want to mount multi-chip 74595, is bound to have a lot to use the I/O port, in order to solve this problem, I will be every 2 sheet 74595 do cascade, and then cascade after all the clock line and the data in parallel and then together (i.e., all 74595 communal clock and data lines, it only occupies two I/O port lines) Finally, for each group latch control lines do individually controlled (equivalent to Chip Select), so that a hardware circuit by a great degree of simplification, both procedures can also share a driving subroutine 74595, to control the type of lock inventory control line, serial data is sent to the port 74595 cascade module. As a result of the hardware and software have a large degree of optimization.)

平面旋转LED资料
平面旋转LED程序
单片机 STC12C5A32S2
运用无线供电方法 旋转起来非常安静
字模软件用的PC2002
实现功能:1.平面显示字体
2.平面显示数字时钟 年月日 星期 如果带了DS18B20 还能显示温度(时钟可调 时钟芯片用DS1302 带后备电池 掉电时钟继续走)
3.平面显示模拟表盘时钟 12、3、6、9显示 指针带箭头(如果上电表盘不完整,可通过遥控器的“快进键“和“快退键”对单列时间进行调整,调整后保存到DS1302RAM中)
4.图片模式 可显示11张图片 按键切换
5.简单动画效果
