关于走字屏的扫描方式的解释【4扫16扫】动画解释
1/4是指先扫描显示所有组的第1行,,点亮所有组第一行的所有应该亮的灯,然后关闭第1行(即第1行所有LED都不亮),接着显示2行,然后3行、最后第4行,再回到第1行,如此循环,1/8指8行一个循环,1/16指16行1循环。1/16循环所需硬件比1/4要少,每个LED显示的时间只有1/16,看起来亮度要比1/4弱。这是为什么呢,
我们把他的扫描周期假设为1,那木16扫的每行的点亮时间就是16分之一,4扫的每行点亮时间就是4分之一,1/16<<<1/4,当然就没有4扫的亮了 nnd,,,同志们不要光看不发表看法,,看会的就高抬你的贵足,,留下点什么,我才有动力去做更好的 我看懂了,以前自己做过16*16的显示一个字的。
最好能把图片下面的字分条写下来,变的比较快。 呵呵我的明白。谢谢老大的解释努力学习中 讲讲8扫吧~~~~{:1_146:} 好好学习天天向上 {:1_137:} 只要看就留下点东西呵呵 hhhhhhhhhhsssdfshhhhhhhhhhh 挺好的谢了顶顶顶 16扫的已经制作成功,8扫。4扫的研究中~~~~ 道理我明白了,我的卡也同时支持4,8.16扫是吗 一个屏幕几百行是怎么扫描的呢 支持非常支持很支持很受益好好学习天天向上 菜鸟终于明白了{:1_146:} 非常详细,不错,好好学习 顶哈啊~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 不错,学习一下,才真正的明白啦。 哦哦 我的明白 谢谢楼主的分享{:1_129:} 楼主的几十元的驱动卡,最多能显示多少个字,怎么计算的呢? 老大的动画演示的真是太精彩了!{:1_85:}
