【摘要】 介绍一种单片机直接驱动光柱显示器件的方法.该方法采用动态扫描的形式直接驱动两个101线光柱.光柱的十位数叫做段码,个位数叫做线数.与段码对应的段叫做当前段,段码减一的段及其以下的段叫做十线全显段.关显示就是关双光柱.更多还原

【Abstract】 A method is introduced to drive the bargraph display devices directly with microcontroller.The double bargraphes in which have 101 lines are driven directly with the method of dynamic scanning.The bit of decade is named code of segment,and bit of the unit is named as number of line.The segment corresponding to the segment code is named current segment,and the segments which their codes are subtracted by one and lower is called segments displayed fully.Shutting display means shutting down two bargraphes.更多还原
