Abstract:

The traditional gas chromatograph peripheral interface circuits are not universal and the microcontroller core of the old gas chromatograph can not meet multidimensional data processing of large patterns requirements.A gas chromatograph control circuitry based on STM32F101VB microprocessor is proposed.The microprocessor,with high performance ARM Cortex-M3 32 bit RISC kernel and enhanced I/O port and APB bus,is applicable to new control core of the gas chromatograph.This design meets the requirements of common interface and multidimensional data processing of modern gas chromatography.

Key words: STM32F101VB;peripheral circuit;the control core of gas chromatograph
