Product description
Buttons are an easy and tactile way to interface with your project, but why would you want to deal with debouncing, polling, and wiring up pull-up resistors? The Qwiic Button with built-in red LED simplifies all of those nasty worries away into an easy to use I2C device. Utilizing Qwiic Connect System, using the button is as simple as connecting a cable and loading up some pre-written code.
Each button has a configurable I2C address, so you can daisy-chain multiple buttons over Qwiic and still address each one individually. An example provides a super-easy way to configure your Qwiic Button to whatever I2C address you desire.
In addition to handling blinking and debouncing, the Qwiic Button has configurable interrupts that can be configured to activate upon a button press or click. Sparkfun has also taken the liberty of implementing a FIFO queue onboard the Qwiic Button where it keeps an internal record of when the button was pressed. This means that code on your microcontroller need not waste valuable processing time checking the status of the button but instead can run a small function whenever the button is pressed or clicked.
