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.
Key words: SPCE061A; Data Acquisition ; UART
