Description: 自己前些天安装了一个6位数码管带4个继电器采用4个独立按钮控制数码管的单片机，其中数码管安装后，就是采用这个方法检测的。采用6位共阳数码管，位控制采用74hc38译码器，段控制采用74HC245，如果能够显示543210，那就说明单片机数码管硬件部分没问题了。(I installed a 6 bit digital tube with 4 relays the other day, and 4 independent buttons to control the digital tube microcontroller. After installing the digital tube, it was detected by this method. The 6 Yang digital tube, position control using 74hc38 decoder, a control by 74HC245, if we can show 543210, it shows that the single-chip digital control hardware no problem.)
