A simple iPhone app controlling a Wasatch Photonics SiG-785 Raman spectrometer.
- XCode 10.1 (Swift 4.2.1)
- jazzy (render docs)
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.)
XCode note: make following patch in Chart.swift:
< lineLayer.lineJoin = kCALineJoinBevel
> lineLayer.lineJoin = CAShapeLayerLineJoin.bevel
I'm new to Xcode and Swift, so leaving some breadcrumbs. These were all useful in learning enough Swift to stand-up the demo:
- Bucky Tutorials
- Stanford Course
- Stack Views
- Zero to BLE
- Core Bluetooth
- Bluetooth SIG membership
- DataControllers and State
- Progress Rings
This is the BLE chip used for the initial SiG-BLE design:
These iPhone apps were also used as 3rd-party confirmation that BLE services were discoverable, and that characteristics could be read and written:
If you have jazzy installed, just type this:
$ make docs
- support in-app dark correction
- add "desc" note field
- add fields to specify URL for cloud upload
- add SW "Raman" mode where laser is enabled prior to ACQUIRE, and disabled as soon as the first spectrum packet is received

- 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
