OpenLog Artemis not detecting KX134 accelerometer


Apologies for the inconvenience. I’m glad the upload is working for you.

It’s rare, but we have seen situations where powering on the microSD card causes the OLA’s power rail to brown-out, putting the OLA into deep sleep. It is microSD card dependent. Some cards cause it, most don’t.

Some solutions / suggestions for you:

Please try removing the microSD card. Then connect via USB to wake the OLA. Or manually press the reset button to wake the OLA. Does the OLA power on and stay on if you do that? Can you then see the serial menu etc?

Please try a different microSD card, if you have one. Does the OLA behave normally with that card?

Last resort, please try the “No Power Loss” version of the firmware ( OpenLog_Artemis-V10-v25-NoPowerLossProtection.bin). That version has the sleep-on-power-loss feature disabled. If the power is lost, or it browns-out, the firmware will reset and keep running instead of going into deep sleep.

Apologies again for the inconvenience. I hope this gets you up and running,
