1、 1632点阵数字钟及汉字显示 作者: HEY | 浏览数 (6070) | 评论数(0) | 2007-08-09一电路原理框架设计制作作品：1632 点阵显示数字钟及汉字显示实现功能：点阵显示的实时时钟以及汉字等字符的左移显示实用特征：采用双电源供电，断电后时钟由电池供电还能继续运行，而且精确性较高实现原理：1 时钟显示是由 DS1302精确的时钟芯片产生时钟信号并将其送至单片机，经过单片机处理后再输送到点阵显示模块。2 汉字显示并左移原理是先写入与本点阵驱动相应的代码进单片机，通过单片机控制程序取表进行处理后送点阵模块显示电路主要模块及原理图：1 单片机最小系统及控制按键电路2 DS13
2、02与单片机接口电路DS1302除了系统上电时由系统供电外，如果主电源断电还有一电池给 DS1302供电，防止断电后 DS1302数据消失。4点阵行驱动模块电路行驱动采用74LS154（416线译码器）及 PNP 三极管，由于是1632点阵显示功率较大故采用8550NP 三极管。5点阵列驱动电路列驱动采用74HC595移位寄存器将控制位级连接入单片机，每个 74HC595数据输入端单独接单片机。1632点阵模块由8块小的88点阵模块通过级连而拼成，共16行，32列。二：主要元器件选择：单片机：AT89S51 采用市场上比较常用的 AT89S51三极管：点阵的行驱动电路用，这里采用 PNP 管，
3、具体型号用8550点阵块：为了电路简单，采用双色8 8点阵晶振：采用的是12MHZ 的晶振电源部分：采用5V 电压供电，采用的是 L7805稳压芯片供电电阻：大部分是限流电阻，阻值为4.7K 或10K，1K译码器：416线采用市场上较为常用的74LS154，用来作行驱动移位寄存器：采用74HC595移位寄存器作列驱动，驱动列端口分配及连接：P1.0P1.2：DS1302与单片机接口P1.3P1.4：K0,K1按键，用来调整时间，按下为0P0：P0口接点阵行驱动电路接译码器P2：P2口点阵列驱动电路接74HC595最后是做好之后的图附：点阵时间显示源程序/=/*标题:16*32点阵数字钟显示程序
