本作品采用Atmel公司的AT89C51单片机,以汇编语言为程序设计的基础,设计一个用四位数码管显示时、分的时钟。在实物图中,左边靠近电源的绿色发光二极管(长亮)是电源指示灯,表示的是5V稳定电源工作正常;单片机左下角红色发光二极管是秒灯,每闪烁一次表示时间走动一秒钟;按键正上方绿色发光二极管是设置灯,当时间正常走动时此时不亮,当第一次按下设置键(右键)时,此绿灯亮,同时秒时熄灭,且分钟的两位数码管出现闪烁,时间停止走动,进入校时状态,表示此时可以进行分钟的调整,当按一次加一键(左键)可实现分钟的加一功能,分钟以60分为极限,超出60分则返回数值0,从0再重新算起;如果再次按下设置键时,这时秒灯和设置灯仍旧保持熄灭和点亮状态,表示分钟的数码管停止闪烁,反过来表示小时的两位数码管则开始闪烁,此时可进行小时的调整,按加1键可实现小时的加1功能,小时调整以24为上限,同样超出24小时则从新回0;当第三次按下设置键时,数码管停止闪烁,设置灯熄灭,秒灯重新闪烁,时间以设定值计时。-err

ST7787 chip SPEC, BYD 2.4inchLCM the SPEC. The ST7787 is a single
ST7787 芯片的SPEC,比亚迪2.4inchLCM的SPEC。The ST7787 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 720 source line and
320 gate line driving circuits. This chip is capable of connecting directly to an external microprocessor, and accepts Serial
Peripheral Interface (SPI), 8-bits/9-bits/16-bits/18-bits parallel interface. Display data can be stored in the on-chip display
data RAM of 240x320x18 bits. It can perform display data RAM read/write operation with no external operation clock to
minimize power consumption. In addition, because of the integrated power supply circuits necessary to drive liquid crystal,
it is possible to make a display system with the fewest components.-ST7787 chip SPEC, BYD 2.4inchLCM the SPEC. The ST7787 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD.
