Description
If you need multiple buttons for your project, fear not! Each button has a configurable I²C address, so you can daisy-chain multiple buttons over Qwiic and still address each one individually. We've got an example in our Arduino library that provides a super-easy way to configure your Qwiic Button to whatever I²C address you desire. You can download the library through the Arduino library manager by searching 'SparkFun Qwiic Button', or you can get the GitHub repo as a .zip file and install the library from there.
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. We've 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 button's status but instead can run a small function whenever the button is pressed or clicked! For more information on interrupts, check out SparkFun's guide here!
