| Abstract: | A high-speed data acquisition system based on TMS320C5402 is proposed. The digital signal processor(DSP) is utilized as the core controller for data sampling,transfer and storing. By the McBSP interface of TMS320C5402 directly linked with the DSP102,the system realizes data acquisition at big capacity,and the shortcomings of the MCU system in operation capability and data disposing speed are overcome. By changing the amplification multiple through DAC signals,the measurement range of the system is improved. The hardware and software of the system are demonstrated in detail,which proves that the system can achieve real-time data processing at high speed with high precision and good reliability. |
