How to setup extra SPI, UART, and I2C serial ports on a SAMD-based boards.

What is an interrupt? In a nutshell, there is a method by which a processor can execute its normal program while continuously monitoring for some kind of event, or interrupt. There are two types of interrupts: hardware and software interrupts. For the purposes of this tutorial, we will focus on hardware interrupts.

Learn how to use serial I2C and SPI buses on your Raspberry Pi using the wiringPi I/O library for C/C++ and spidev/smbus for Python.

How to eschew the Arduino IDE for a combination of and Arduino command-line tool (Arduino CLI) and a professional code editor (Visual Studio Code).

An introduction to the Atmel ATSAMD21G18 microprocessor and our Mini and Pro R3 breakout boards. Level up your Arduino-skills with the powerful ARM Cortex M0+ processor.

This tutorial covers the basic functionality of the RedBoard Plus. This tutorial also covers how to get started blinking an LED and using the Qwiic system.

Skip the bootloader and load your program directly onto an AVR with the AVR Pocket Programmer.

A how-to on the Tiny AVR Programmer. How to install drivers, hook it up, and program your favorite Tiny AVRs using AVRDUDE!

This tutorial will teach you what a bootloader is and why you would need to install or reinstall it. We will also go over the process of burning a bootloader by flashing a hex file to an Arduino microcontroller.

A quick tutorial showing how to reprogram the ATtiny85 IC found on the LilyTiny or LilyTwinkle boards.

Want to take a stab at advancing your programming skills? Check out the Thing Plus - RP2040, with the first microcontroller from the Raspberry Pi Foundation. This guide will get you started working with the RP2040 and programming in MicroPython and C/C++.

How to program SAMD21 or SAMD51 boards (or other ARM processors).

This tutorial covers the basic functionality of the SAMD51 Thing Plus and highlights the features of the new ARM Cortex-M4F development board.

This guide will help you get the RED-V RedBoard or Thing Plus up and running for the exhaust port. Depending on personal preference, there are a few environments to get started with the boards. All wings report in... we're going in full-throttle.

How do I install a custom Arduino board/core? It's easy! This tutorial will go over how to install an Arduino board definition using the Arduino Board Manager. We will also go over manually installing third-party cores, such as the board definitions required for many of the SparkFun development boards.
