WaveformPlotterExample is an iOS application written in Swift. This repository only has the minimum set of UI classes and configuration settings (XCode files, Settings.bundle, etc) to launch the plotting interface. The main functionality is provided by the following Swift Packages:
- swift-waveform_plotter: A library to plot physiological time-series such as the Photoplethysmogram (PPG).
Examples of other applications making use of the above Swift Packages are:
- swift-thermal_recorder: Record video from thermal cameras such as the FLIR One.
- swift-pulse_ox_recorder: The main application (XCode, Settings.bundle, etc) to record time-series data from devices that support Bluetooth Low Energy (BLE) protocol.
- swift-sensor_recording_utils: A module containing shared utility methods and classes used by other modules and applications to record raw data from sensors.
- swift-async_bluetooth: A Swift Package that replicates some of the functionality provided by Apple's CoreBluetooth module but using Swift's latest async/await concurrency features.
- swift-async_pulse_ox: The main module that has all the functionality to connect and record data from devices that support Bluetooth Low Energy (BLE) protocol, such as heart rate monitors and pulse oximeters.
The image below shows an example of plotting a sinusoidal waveform using the synthetic waveform generator found in the swift-waveform_plotter Swift Package:
