This repository provides the source code for our research paper "PTP-Synchronized Tri-Level Sync Generation for Networked Multi-Sensor Systems" (Published Article). This Arduino compatible library has been created to provide a Tri-Level Sync signal generation based on a PTP-Synchronized clock for the Teensy 4.1 microcontroller platform.
This library was created by the Architectures and Systems Group of the Institute of Microelectronic Systems (IMS/AS) at the Leibniz University in Germany.
(based on the ptp library)
- Teensy 4.1 with Ethernet adapter
- Working Teensy Arduino environment
- PTP-branch of QNEthernet Library with our patches: https://github.com/HedgeHawk/QNEthernet/tree/ieee1588-2-fix
- Clone the library folder to your Arduino-libraries path
- Restart Arduino IDE
Additionally to the PTP Slave and PTP Master example of the base repository, an extra example is provided for the generation of the Tri-Level Sync signal generation.
The signal generation requires an extra electrical network connected to the microcontroller. The schematic can be seen here:
The lower and higher pin for the example are pin 10 and 12.
