Welcome to the Open-seismic wiki!

In this wiki page you will find details about the Open-seismic project goals, design guidelines and current stage of developement. The details about the librairy used in the projects can be found in the command and ad7768 pages.

What

The Open Seismic hardware initiative is to design an open source VSP tool that is modular and can be reused or adapted by other research group for their purposes. This repo is hosting the software required to operate the electronics of the VSP tools. In particular the systems in composed of :

  • Analog accelerometer from Silicon Design (SI1521L)
  • AD7768 multi-channel Delta-Sigma 24 bits ADC
  • THVD8000 Frequency modulated RS-485
  • Teensy 4.0 MC

Scheme

There are multiple Workers (capsule) but only one master uphole.

Design guidelines

software scheme

Main elements in master scripts:

  • mainSlave
  • mainMaster
  • main.py
