aducm355官方历程 M355_ECSns_EIS 历程。void AD5940ImpedanceStructInit(void)函数,我修改电压出现问题

Thread Summary

The user modified the Vzero voltage from 1100mV to 500mV, resulting in a square wave-like voltage on the SE0 pin during EIS measurements. The issue arises because SE0 switches between 1.1V (HSTIA bias during measurement) and 500mV (LPTIA bias during initialization). The accompanying answer confirms that the measured waveform is VSE to ground.

这个代码里的 pImpedanceCfg->SensorCh0.Vzero = 1100;                  /* Set Vzero = 1100mV. Voltage on SE0 pin*/
我修改为500mv

用示波器测得的电压呈现,下面这种类似于方波的型状,是为何?

用默认的1100mv,就是一条直线,其他配置参数我没改,全是默认,就改了Vzero的电压
