AC Real-time Sampling System Based on DSP2812

    Graphical Abstract
    • Abstract
  • In this paper, an AC circuit sampling system design is presented based on the TMS320F2812 DSP, which is composed of closed-loop Hall sensor, signal preprocessing circuit, digital signal processor DSP2812 and error correcting circuit. Furthermore, the hardware circuit and software programming for the AC circuit sampling system are completed, and the gain error and the offset error caused by DSP2812 internal ADC module are corrected by software algorithm, and the acquisition accuracy of it is improved.
