频率计，精度高，可以自动换档，一般单片机可以达到0…500k

大值的驱动电压，否则会造成液晶模块的损坏。如果在低于或大致等于典型驱动电压时，观察到了显示屏上有色调的变化，即显示域的底色略深于边缘的颜色，表明液晶模块电源连接正确，可以进人下一步工作。如-Large value of driving voltage, otherwise LCD module can cause damage. If less than or roughly equivalent to a typical drive voltage, the observed screen has color changes, which indicates that the domain a little deep background color at the edges, indicating that the LCD module power supply connections are correct, you can enter the next step. Such as
