SparkFun OpenLog Artemis (DEV-16832) with Digital Low-Pass Filter and RTX

Development Boards Artemis
1

i use the SparkFun OpenLog Artemis with the WIFI module (ESP8266), transfer the data by the WIFI (by RX and TX). If i change the DLPEnableStat to true:

ICM_20948_Status_e accDLPEnableStat = myICM.enableDLPF( ICM_20948_Internal_Acc, true );

ICM_20948_Status_e gyrDLPEnableStat = myICM.enableDLPF( ICM_20948_Internal_Gyr, true );

the signal interference will become severe.

How can i fix this problem?

(left one without DLPF , right one when DLPEnableStat is true)

Thanks for reaching out to us on this.

Refer to the “Configuration” section of the hookup guide here: https://learn.sparkfun.com/tutorials/op … -guide/all

The section covering “Configure the IMU Logging” mentions how to define the DLPF bandwidths.

Hope this helps, and happy sparking!
