🔧 Raspberry Pi Configuration Scripts

Automated setup for GPS + PPS integration, serial configuration, and system diagnostics on Raspberry Pi.

---

🧭 Overview

This repository contains a collection of shell scripts for configuring a Raspberry Pi — focused on GPS and PPS (Pulse Per Second) signal integration, serial port setup, and PPS module verification.

These scripts automate repetitive setup tasks and ensure a consistent configuration for time synchronization, NTP servers, and GPSD services.

Setup GPS and Serial Port

The script setup_gps_and_serial.sh automates the process of setting up a Raspberry Pi for GPS and PPS integration. It performs the following tasks:

• Updates package lists and upgrades installed packages.
• Updates the Raspberry Pi firmware.
• Installs necessary packages for GPS and PPS.
• Configures /boot/config.txt for PPS signals.
• Adds 'pps-gpio' to /etc/modules.
• Configures the serial port using raspi-config.

To download the script :

wget https://github.com/FilipooSVK/rpi_ntp/raw/main/scripts/setup_gps.sh

To run the script, make it executable and execute it:

chmod +x setup_gps.sh
./setup_gps.sh

Configure Serial Port

The script configure_serial.sh configures the Raspberry Pi's serial port by using raspi-config. It disables the login shell over serial and enables the serial port hardware.

To download the script :

wget https://github.com/FilipooSVK/rpi_ntp/raw/main/scripts/configure_serial.sh

To run the script, make it executable and execute it before running the GPS configuration script:

chmod +x configure_serial.sh
./configure_serial.sh

Edit /etc/default/gpsd

The script edit_gpsd_config.sh edits the /etc/default/gpsd file to change the GPSD_OPTIONS and DEVICES values. It performs the following tasks:

Sets GPSD_OPTIONS to "-n". Sets DEVICES to "/dev/ttyS0 /dev/pps0". Restarts the gpsd service to apply the changes.

To download the script :

wget https://github.com/FilipooSVK/rpi_ntp/raw/main/scripts/edit_gpsd_config.sh

To run the script, make it executable and execute it:

chmod +x edit_gpsd_config.sh
./edit_gpsd_config.sh

Check PPS Module

The script check_pps_module.sh checks the PPS module by running lsmod | grep pps and sudo ppstest /dev/pps0. It displays the results for both commands.

To download the script :

wget https://github.com/FilipooSVK/rpi_ntp/raw/main/scripts/check_pps_module.sh

To run the script, make it executable and execute it:

chmod +x check_pps_module.sh
./check_pps_module.sh

Note: The check_pps_module.sh script will display the results of the sudo ppstest /dev/pps0 command in full.
