Description: ad转换的C语言程序，硬件部分由AT89C51,MAX232，ADC0809，NF555组成，555用来产生ADC0809的CLK，现在好像是300多K，输入电压直接加在ADC0809的IN0，因为我只用一路所以ADC0809的 A、B、C三个进址我直接接地。ADC0809的ALE和StartART我连在一起由单片机的P3.4控制。-ad conversion C-language program, the hardware part by AT89C51, MAX232, ADC0809, NF555 composition, 555 used to generate the ADC0809' s CLK, it seems that it more than 300 K, the input voltage directly added to the ADC0809' s IN0, because I only use all the way so ADC0809 The A, B, C three sites I went straight into the ground. ADC0809 of ALE and StartART I linked to the P3.4 controlled by the microcontroller.

Description: AT89C2051作為AT89C51的簡化版雖然去掉了P0、P2等埠，使I/O口減少了，但是卻增加了一個電壓比較器，因此其功能在某些方面反而有所增強，如能用來處理模擬量、進行簡單的模數轉換等。本文利用這一功能設計了一個數位電容表，可測量容量小於2微法的電容器的容量，採用3位元半數字顯示，最大顯示值為1999，讀數單位統一採用毫微法（nf），量程分四檔，讀數分別乘以相應的倍率。 -AT89C2051 The SG7800A/SG7800 series of positive regulators offer self contained, fixed-voltage capability with up to 1.5A of load current and input voltage up to 50V (SG7800A series only). These units feature a unique on-chip trimming system to set the output voltages to within ±1.5 of nominal on the SG7800A series, ±2.0 on the SG7800 series. The SG7800A versions also offer much improved line and load regulation characteristics. Utilizing an improved Bandgap reference design, problems have been eliminated that are normally associated with the Zener diode references, such as drift in output voltage and large changes in the line and load regulation.
