README

GPS timestamper project

Open-source device based on STM32 that provides precision time stamps of trigger signal connected to input. It use GPS PPS signal to provide ~1uS precision time mesurment. Also it makes self-calibration by PPS every second.

Device may be used to synchronize any signals and data streams without wired or wireless connection i.e. in geophysical researches, lightning detection networks, seismology and others

Currently project in protortype state and under development. Primary function (precision timestamping) works correctly.

Build

To build firmware you may have installed arm-gcc toolchain on your linux system. If you do not need unit tests, simply comment out corresponding line in root CMakeLists.txt (to build tests gtest should be installed on your system)

Run build.sh and thats all. To flash MCU, connect ST-Link device to PC and then run flash.sh.
