单片机2408点阵时钟电子制造

这是一个单片机2408点阵时钟电子制造,用单片机直驱点阵，这儿用的是STC89C52,驱动才能不是很好,有条件的话用STC12C5A60S,驱动才能现已比较好，屏的亮度会比较高。图中是用STC89C52单片机，直驱三个8*8的共阳点阵屏，亮度还根本能够，白日看都很清楚!P0口需求接上1K的上拉电阻，P1-P3口别离接三个8*8屏的阴极,用去了单片机的悉数32个I/O口。为了能调时刻,P2口的P2.0-P2.6接屏的1-7列，P2.7口接一个按扭作于调时刻，调整办法: 长按一次是进入调时状况，短按是加1，长按二次是调分，短按是加1，长按3次回复正常状况! 感兴趣的爱好者能够着手实践一下，体会一下电子制造点阵时钟的趣味。
