Openview 2 is designed as a companion application to receive data from various Protocentral boards. It can be used to visualize the data in real-time and also store the data in CSV format.
OpenView 2 will replace the existing OpenView app written in Processing and will be the primary supported app for all Protocentral boards. OpenView 2 is based on the more modern Flutter framework and is available for Windows, MacOS, Linux, Android, and iOS.
The Android and iOS mobile versions use BLE to connect to the boards (when used with a microcontroller with BLE support), while the desktop version uses USB/UART to connect to the boards.
- Multiple boards, one unified interface
- Mobile platforms: Android and iOS
- Desktop platforms: Windows, MacOS, and Linux
- Code development environment: Flutter
- Data storage option to CSV files
- You can add your own board by editing the source (for now, in the future we will add a more configurable way to add new boards)
You can download the latest version for your operating system from the Releases page.
OpenView 2 is written on the Flutter and is fully open source. You can compile your own from the source code provide in this GitHub repository.
