AT89C52单片机编程求大佬帮忙！ 51单片机lcd显示屏型号是LM016L，有3个按键K1、K2、K3，按下K1显示屏上第一行显示的是“worktime:1h”，8个led流水灯工作时长变为1小时；再按一下K1屏幕上第一行显示屏上显示的是“worktime:2h”，8个led流水灯工作时长变为2小时。按下K2显示屏上第二行显示的是“fre:2s”，8个led流水灯闪烁频率变为2秒；再按下K2显示屏第二行上显示的是“fre:4s”，8个led流水灯闪烁频率变为4秒；按下K3显示屏上第二行显示的是“mod:dou”，8个led流水灯一次亮两个，再按下K3显示屏上第二行显示的是“mod:sin”，8个led流水灯一次亮一个.

我们给客户供一款芯片运用在开关上面的，发现有5个没声音也没通讯的，正常情况下，开关一上电就会有叮咚的提示音想起，但这5个开关要上电后没声音也没通讯，等15秒左右通讯又恢复了。开关重烧程序后也不行，换一个新的芯片后才可以，这种情况是什么问题导致，有大神解答吗

为什么会放大到20多伏，是不是相当于输出了10+10的供电电压？不应该相当于放大了2+1倍吗？最大15V

写入地址0时地址1会改变，写入地址1时0也会改变，写2的时候3会改变 使用的是16位模式，按照手册的电路地址偏移一位（个人理解偏移一位地址就相当于+2）

在rk3568板子上运行屏幕共享app时，出现系统重启，目前出现系统重启有两种情况，1、板子正常网络环境下接收流时大概运行2个小时左右出现重启，出现重启的征兆大多数是在画面出现卡顿时；2、使用平板推流，将平板移动到弱网情况下，rk收流端很容易复现系统重启问题。 通过adb logcat 拉取应用日志时，重启前没有发现有什么异常报错信息，重启的时间节点是：11:35:26.378 AdbProcessImpl::out:04-12 11:35:17.260242372 E drm-vop-356x: invalid value iFirst=-1, iLast=0 04-12 11:35:17.28514821629 W HidlServiceManagement: Waited one second for android.hardware.radio@1.1::IRadio/slot1 AdbProcessImpl::out:04-12 11:35:17.285148148 I hwservicemanager: Since android.hardware.radio@1.1::IRadio/slot1 is not registered, trying to start it as a lazy HAL. 04-12 11:35:17.28714821629 I HidlServiceManagement: getService: Trying again for android.hardware.radio@1.1::IRadio/slot1...

最近想用stm8l做一个led表，需要用到触摸功能。大家有没有用过官方的触摸库，好用吗？效果如何，灵敏度好吗？

如题所示，使用STOP低功耗模式，功耗下来了，STOP模式每次最大只能32秒左右（RTC寄存器满了），所以就循环多次（5分钟就是10次左右）。 启动时读取一次ADC数据（电池电压比如是4.10V），进入STOP，RTC唤醒后读出来的ADC没有变化（依然是4.10V）。以前没有进入STOP模式，连续读取是OK的。 请问大虾，这大概是什么问题？
