I cannot currently configure my Openlog Artemis using Tera Term because I am not allowed to install the driver for the CH340 chip. I have applied for permission, but in the meantime, I would like to get started with gathering data.
Unless I am mistaken, the spec sheet for the ICM-20948 says that it should be able to gather gyroscope data at 9 kHz, accelerometer data at 4.5 kHz, and magnetometer data at 100 Hz.
Is there a way for me to change the text config file in the microSD card to have it gather data at a higher rate such as those mentioned in the spec? I don’t really need 9 kHz, but the 10 Hz I got when I just had it start with whatever the default configuration really isn’t enough. At a minimum, I need over 100 Hz.
Is there any documentation on the options in the config text file that I could read, so I can learn about what I would need to change to get the configuration that I want?
Here’s a copy of my sample OLA cfg file (found on SD card after a period of logging)

The files is freely edited if you put it in a an SD card reader. So…a bit of yes and no (most of the options are ‘big buttons’ that change many global settings, instead of per-sensor…but there are a few fo gyro/IMU)
