Abstract:

A functional stimulator based on STM32F103VET6 is introduced,which uses double DAC regulation circuit to address the nonlinear problem caused by DAC module near the 0 level.Several typical voltage values are used on the output regulation circuit to obtain the correction parameters of the corresponding revision.The output waveform shows that the design ensures the linear characteristics of the output voltage.

Key words: STM32F103VET6;functional electrical stimulation;nonlinear
