Study on the communication scheme of signal modulation and demodulation based on serial interface;

PCB of micro controller serial interface for experiment;

RS—485 Serial Port and Industrial Control Local Area Network;

Using a low-power CMOS 8-bit microcontroller ATmega8,ten-bit digital signals realizes analog-to digital conversion,and the converted signals are transmitted into the PC by RS232 serial port.

This paper introduces a design scheme of a serial port communication technology based on embedded gateway.

Integrated TTS processor SD178A and its series interface;

The characteristics of thesystem ,the series interface circuits and the useful anti-interference methods used in thesystem have been analysed.

This paper designs a series interface between ARPA (JAS-800 for example) and speech output system.

Using the SPI serial interface and the MC14489 management chip constitute the intellectualized instrument measuring appliance,the demonstration actuation electric circuit to be possible to cause the systems performance price compared to obtain the large scale enhancement.
