ADS1256的采样问题

Other Parts Discussed in Thread: ADS1256

我用stm32f103控制ads1256采样。采样点接到电池,采样正常。

我将采样点接到stm32的gpio上(3.0v),拉高,采样,拉低,采样。那么问题来了:

我设置采样率为30K时,数据:

1282.5682740mV
 1864.7996120mV
 1283.2906580mV
 1864.7105100mV
 1282.3547880mV
 1866.3639800mV

采样率设置为100sps时:

106.5600120mV
 3076.1658200mV
 106.5474540mV
 3076.0683460mV
 106.5217400mV
 3076.5587060mV

我感觉芯片里面是不是做了个缓冲计算平均值? 我有没有办法不要读平均值,采样多少就是多少?谢谢
