我的其他四个导联的信号是通过以下公式得来的:
III = II - I;aVR = -(I + II)/2;aVF = II - I/2;aVL = I - II/2;
请问我的WCT寄存器应该如何设置?
如果设置成下面的形式对吗?
WCT1=0x0B; //Power on WCTA and connected to RA
WCT2=0xD4; //Power on WCTB and connected to LA,Power on WCTC and connected to LL

对,外部有连接,内部不用置位。 导连脱落检测有DC AC两种模式,其中DC lead off有分两种形式Pull up/down resistor, 及current source,可以灵活选择。当然所有这些方式会受到人体阻抗差分输入的影响,其中电极和人体接触松紧程度影响最大。 但都是可接受范围内,请问你的偏差很大吗?
脱落检测不稳的话可以调整COMP_TH寄存器,它是控制内部比较器的灵敏度的。
