恳请TI工程师、开发人员指点。关于ads1298做5电极心电原理图的问题。(有附图)

Other Parts Discussed in Thread: ADS1298

本人正在ads1298做心电,想用5电极,分别左右臂,左右腿,胸部5个位置。不知5电极这样连接ads1298是否正确?右腿驱动电路是否可以这样

另外有几个问题:

1:mcu可否用stm32f103,stm32速度是否跟得上,一般都用什么mcu呢?

2:mcu 与 ads1298连接是否 只连接 SPI四根线(DIN  DOUT /CS SCLK)和/DRDY   START 即可控制ad转换?

谢谢看到帖子的各位。
