Hello,
The Geophone Logger code is old. I wrote it for the original SparkX version of OLA - X04, with the black circuit board. Looking at the binaries folder, it looks like I never compiled a binary for the SparkFun version - v10 with the red circuit board.
I will try to find time to compile a new binary for you.
The latest version of the OLA firmware is v2.1. Please make sure you are using the correct version for your board. If you have the red circuit board, you need OpenLog_Artemis-V10-v21.bin - not OpenLog_Artemis-X04-v21.bin.
Best wishes,
Paul
