Research on the acquisition of cylinder pressure in internal combustion engine based on DSP [Copy link]

This paper introduces the research of cylinder pressure acquisition system based on DSP56F807, a single-chip computer with high-speed digital signal processing function. The hardware of internal combustion engine pressure acquisition system using USB transmission module is developed, and the data acquisition, USB communication and display programs are compiled using the analog-to-digital conversion and input capture functions of DSP. The basic functions of the acquisition system are verified by experiments.
