A high-speed and low power multifunction digital adjustable source of resonant excitation based on Cortex-M3(STM32F103C8) chip is introduced in this paper.The emphasis is put on the discussion of  the CPU part,signal module,filter and amplifier module,and the software of the control system.Actual measurement shows that the digital adjustable resonant source has the advantages of USB Interfaces and high resolution over the traditional analog resonant source.The resonant source can not only be used to complete experiments about resonance,but also have broad application prospects.

Key words: Cortex-M3;DDS;resonant source;USB
