| Abstract: | This paper introduced one kind scheme based on the DSP and MCU to realize multi-purpose electric quantity analysis. The system that DSP constitutes is completed to voltage together with current sampling at a high speed, then using the FFT' s algorithm to analysis voltage and current, and calculates all electric quantity; The system consisting of 89C58 is to control keyboard and 320*240 LCD; The data exchange between the DSP and MCU is by twin port RAMs. |
