[摘要]：SPCE061A是一款具有語(yǔ)音處理功能的16位單片機(jī)。它具有豐富的外設(shè)資源和良好的監(jiān)控機(jī)制使該芯片功能豐富、性能穩(wěn)定，可作為通用微控制器，廣泛應(yīng)用于工業(yè)控制、家居安防、智能家電等眾多領(lǐng)域。
本文主要介紹了SPCE061A在電壓數(shù)據(jù)的采集上的應(yīng)用。首先，制作了一個(gè)正弦信號(hào)發(fā)生器，以用來(lái)產(chǎn)生頻率可變的正弦信號(hào)。其次，制作了電壓頻率轉(zhuǎn)換電路，用來(lái)將正弦信號(hào)轉(zhuǎn)換成0-5V的電壓信號(hào)。第三，用分壓電路將電壓分為0-3.3V電壓以便采集。第四，利用了一個(gè)I/O口連接數(shù)據(jù)引腳，將采集的數(shù)據(jù)進(jìn)行模數(shù)轉(zhuǎn)換。最后，利用I/O口與RS232實(shí)現(xiàn)與PC機(jī)的數(shù)據(jù)通信。

The serial data acquisition system based on 16-bit microcontroller

Abstract: SPCE061A is the16 monolithic integrated circuit.that having the rich peripheral device resources and the good monitoring mechanism causes this chip has rich functions and the stable property,it .As a general micro controller, It applied widely in the industrial control, keep the living circumstate safe ,the intelligent electrical appliances and so on numerous domains.
This article mainly introduced SPCE061A application in the voltage data gathering. First, a sinusoidal signal generator has been manufactured, using to produce frequency variable sinusoidal signal. Next,it has manufactured the voltage to frequency switching circuit to transform the sinusoidal signal to the 1-5V voltage signal. Third, using the bleeder circuit divides the 0.66-3.3V voltage to gather . Fourth,it has used a I/O interface to connect the data pins, to convert the gatherd data to the digital-data. Finally, using the I/O interface and RS232 to communicate with the PC.
