Swiftpack.co - Package - WasatchPhotonics/Wasatch.Swift

Scope Mode

Overview

A simple iPhone app controlling a Wasatch Photonics SiG-785 Raman spectrometer.

Building

Dependencies

  • XCode 10.1 (Swift 4.2.1)
  • jazzy (render docs)

CocoaPods

On MacOS, install CocoaPod package manager using HomeBrew:

$ brew install cocoapods

To install pods used by SiGDemo, use:

$ git clone git@github.com:WasatchPhotonics/Wasatch.Swift.git
$ cd Wasatch.Swift
$ pod install

The current version of SwiftCharts seems to have a single line that needed changed...something about a bevel. Xcode knew how to fix it, but I had to use "Manage Schemes" to expose the SwiftCharts scheme for editing in Xcode, then a ⌘-B to build the framework and find the problematic line.

(Note that Jazzy installation seems to prefer gem over brew...YMMV.)

Charting

XCode note: make following patch in Chart.swift:

< lineLayer.lineJoin = kCALineJoinBevel
> lineLayer.lineJoin = CAShapeLayerLineJoin.bevel

References

I'm new to Xcode and Swift, so leaving some breadcrumbs. These were all useful in learning enough Swift to stand-up the demo:

This is the BLE chip used for the initial SiG-BLE design:

Testing

These iPhone apps were also used as 3rd-party confirmation that BLE services were discoverable, and that characteristics could be read and written:

Backlog

Version 1.0

  • support in-app dark correction
  • add "desc" note field
  • add fields to specify URL for cloud upload

  • refresh BLE table on disconnect

Version 2.0

  • support compound matching / identification
  • make BLE screen more like Settings
    • two sections, "Connected" and "Available"
    • add little blue checkmark by connected device
    • change RSSI percentage to WiFi range icon

Version 3.0

  • Apple Watch (no real point until compound ID working)
