SPI communication in the monitor system of power quality
Zhaohua Yang · Journal of Foshan University · 2010
Based on the study of the monitor system of power quality,the distributed control structure which combines ARM and DSP is proposed to be used widely for the modern measuring instruments.This paper highlights the analysis of the technical difference of SPI interface made by different manufactory.With the consideration of the need of the monitor system of power quality,a solution to the SPI communication between ARM and DSP is proposed.
