Buttons handling library for Raspberry Pi Pico / Pico 2

Overview

This project is a library for handling multiple buttons on Raspberry Pi Pico / Pico 2

This project features to detect:

• Single Push event
• Repeated Single Push event
• Multiple Push event (exclusive with Repeated Single)
• Long (Long) Push event (exclusive with Repeated Single)
• Switch On/Off events

Notes

• If Multiple detection enabled, time lag defined by 'actFinishCnt' is needed to determine action
• Repeat count information of Repeated Single detection is served for UI items to accelerate something by continuous button push
• Use NewButtonConfig() for customizing button detection parameters other than default configurations

Supported Board and Device

• Raspberry Pi Pico
• Raspberry Pi Pico 2

How to build

• See "Getting started with Raspberry Pi Pico"
• Put "pico-sdk", "pico-examples" and "pico-extras" on the same level with this project folder.
• Set environmental variables for PICO_SDK_PATH, PICO_EXTRAS_PATH and PICO_EXAMPLES_PATH
• Confirmed with Pico SDK 2.1.1

> git clone -b 2.1.1 https://github.com/raspberrypi/pico-sdk.git
> cd pico-sdk
> git submodule update -i
> cd ..
> git clone -b sdk-2.1.1 https://github.com/raspberrypi/pico-examples.git
>
> git clone -b sdk-2.1.1 https://github.com/raspberrypi/pico-extras.git
>
> git clone -b main https://github.com/elehobica/pico_buttons.git

Windows

• Build is confirmed with Developer Command Prompt for VS 2022 and Visual Studio Code on Windows environment
• Confirmed with cmake-3.27.2-windows-x86_64 and gcc-arm-none-eabi-10.3-2021.10-win32
• Lanuch "Developer Command Prompt for VS 2022"
