how to build a precision time server. (optional) how to add a 4x20 LCD to display server status and GPS and PPS information. While you can use any model of Raspberry Pi to implement a Stratum-1 NTP ...

This is a port of Arduino to the RP2040 (Raspberry Pi Pico processor) and RP2350 (Raspberry Pi Pico 2 processor). It uses the bare Raspberry Pi Pico SDK and a custom GCC 14.3/Newlib 4.5 toolchain and ...

The Raspberry Pi Compute Module form factor is a tantalizing core for a potential laptop, with a CM5 module containing a fairly beefy SoC and RAM, with depending on the exact module also eMMC storage ...

Sometimes, you don't have direct access to the Raspberry Pi running your project. Perhaps it's installed outdoors with no display and keyboard attached. Or maybe it was squeezed into a compact chassis ...

A Raspberry Pi 5 has the ability to capture video via attached cameras and access the Internet using wired and wireless protocols, all while driving a pair of personal computer displays. However, if ...

More often than not, an IoT master device uses the SPI (serial peripheral interface) and I 2 C (inter-integrated circuit) protocols to exchange data with EEPROMs or sensors that are operating in slave ...

The Raspberry Pi RP2350 microcontroller adds an HSTX (High-Speed Serial Transmit) interface adding the PIOs (Programmable IOs) introduced on the Raspberry Pi RP2040 three years ago. The RP2350 MCU now ...

For years, there has been a clear distinction between the Arduino and Raspberry Pi boards. There are some things the Arduino can do that the Raspberry Pi can't, and vice versa. When you think of ...

Cavin McKinley’s BreadboardOS is an open-source firmware platform for the Raspberry Pi RP2040 MCU (for now) built around FreeRTOS and with a feature-packed CLI that reminds me of the Linux terminal.

The Raspberry Pi dominated the maker scene for a decade. Supply chain problems then brought the high flying to an end. With the Raspberry Pi 5, the Raspberry Pi Foundation is now attempting to break ...

The Raspberry Pi is a popular and economical single-board computer with a ton of exciting use cases. If you have one and want to check your Raspberry Pi version or other system information like CPU ...
