11.27固件未能修复存在电压不正常的问题。具体表现为开机接入充电时电压会显示16-24V来回跳动(可能和插头有关,有的插头会出现,有的不会),然后电池显示电压降到3.58V后,显示电压会直接从3.58V跳到2.80V,再从2.80V开始继续下降(这个问题普遍存在,每一次充放电都会复现,而且验证了两块PCB都会有这个问题)。当显示电压降到2.56V,电压显示数字会维持2.56V不变。此时关机并且屏幕熄灭以后,发现4117模块仍然处于工作状态,并且pcb已经不能正常开机,需要长按开关键复位后才能开机。放电一段时间让显示电压低于2.56V以后,重新开机,电压又会变回3.2-3.3V,然后逐渐降到3.0V左右自动关机

试一下现在这版,刚刚参考国外网站的教程重写了串口初始化代码,经过简单测试暂时没出现干扰问题
