What is an interrupt? There is a method by which a processor can execute its normal program while continuously monitoring for some kind of event, or interrupt.
The SparkFun RedBoard Qwiic is the newest edition of the Arduino-compatible development platforms it is designed to be an easy-to-use learning platform for coding, physical computing, and project prototyping.
SERCOM (Serial Communication) is a multiplexed serial configuration used on the SAMD21, SAMD51 and other boards. It allows you to select various serial functions for most of your pins.
The Qwiic RFID ID-XXLA is an I2C solution that pairs with the ID-LA modules: ID-3LA, the ID-12LA, or the ID-20LA, and utilizes 125kHz RFID chips. Using the product's interrupt pin, we'll discuss how to get, store, and compare unique RFID IDs.
SparkFun ProDriver and Mini Stepper Motor Driver utilize the latest TC78H670FTG stepper motor driver from Toshiba. With two different methods for control (serial communication or clock-in stepping) this is a great option for your next project that requires precise motor control.
The SparkFun LiPo Fuel Gauge - MAX17043 connects your LiPo battery to your project and uses a sophisticated algorithm to detect the relative state of charge and direct A/D measurement of battery voltage.
The SparkFun Analog MEMS Microphone Breakout makes it easy to work with the Vesper VM2020 analog microphone. The VM2020 is an ultra-high Acoustic Overload Point (AOP), high dynamic range, differential analog output piezoelectric MEMS microphone.
