我们在生活中经常用到数字表,但是指针式的数字表精度低而且功能少,有时并不能满足我们的需要,而采用单片机设计的数字表就可以弥补这些缺点,而且具有较强的抗干扰性。本次课题设计的多路数字电压表将会在以后的生活中有广泛应用。 We often use digital watches in life, but the pointer digital table with low accuracy and functionality, and sometimes can not meet our needs, and the use of digital single-chip design table can make up for these shortcomings, but also has strong anti-interference Sex. The multi-channel digital voltmeter designed in this project will be widely used in later life.
