+= The Go Smart Watch

+v0.1.0, 2025-12-01

+Authors: {authors}
+
+This document can also be accessed in PDF form via an AWS bucket. Normal GitHub
+uses Asciidoctor, the standard Asciidoc renderer to render AsciiDoc. If this
+feature is not supported, Asciidoc is very readable as plain text. This is also
+why it was chosen over Markdown.
+
+== Abstract
+This document acts as a report to describe the purpose of the project, what each
+component in the project does and why said components are necessary. The report
+also details on similarities and differences from this project to other
+real-world embedded systems, and also talks about how certain things might have
+been done differently.
+
+== Purpose
+The Go Smart Watch is intended to be the "jack of all trades" smartwatch. Not
+only can it act as a fitness tracker by keeping track of the steps taken and the
+calories while wearing it, but also has a framework which enables potential for
+many more apps, such as utility apps and games.
+
+== Component Description
+. Espressif `ESP32-C6` (or `ESP32-C6-MINI-1U`): main microcontroller
+. SparkFun Battery Babysitter: battery power for the smartwatch. A smartwatch
+ must be portable and easily reusable. This board allows using a rechargeable
+ LiPo battery with the smartwatch.
+. Push Buttons: Act as user input. Two buttons mimic a rotary encoder and the
+ third one acts as a 'select'. There is a global 'back' button and an
+ application specific 'red' button.
+. SD Card: User-configurable settings that would be hard to change in the watch
+ interface. This includes things like Wi-Fi usernames and passwords that would
+ be annoying to type using the 5-button controls.
+. IMU: Accelorometer whose data can be extrapolated to form a step count.
+. uLCD-144-G2: This is a display which shows watch output. Using a screen
+ instead of a mechanical watch face allows a lot of versatility.
+
+== Similarities and Differences
+* **Apple Watch:** The Apple Watch is an IoT-enabled wearable device
+ manufactured by the Cupertino based company of the same name. Other than
+ showing the time, this watch has a versatile collection of apps that enable it
+ to be used for a plethora of other purposes, including but not limited to
+ contactless payments, calling, messaging and fitness tracking.
++
+While SWOS (the FreeRTOS-based OS Go runs) does not have an App Store, it does
+not take much effort to add new apps. There is a built-in Clock app that can
+sync to the current time using Wi-Fi, and a pedometer that can count the steps
+and calories one has taken.
++
+Due to cost limitations, the Go does not have the plethora of sensors that the
+Apple Watch has, such as a heart rate sensor. It also does not have a proper
+implementation of a rotary encoder, substituting it with pushbuttons instead.
++
+The Apple Watch does not have expandable storage support with SD cards.
+
+== Improvements
+* **Rotary Encoder:** If the part could've been procured in time, the team would
+ have used a rotary encoder as the primary scrolling and selection interface to
+ the watch in lieu of the triple-button system.
+* **Settings App:** A user-friendly Settings app would have been added that
+ would allow the user to change their weight, height and adjust the current
+ time zone.
+* **Icons:** The team was unable to get the `BLIT` instruction of the uLCD to
+ work. If they had gotten these to work, apps would have had icons displayed.
+* **Printed Curcuit Board:** Due to the time constraints of the class, the team
+ was unable to get the printed circuit board and its necessary SMD components
+ ordered in time. The team would have made a simpler, less compact THT version
+ which would not have required as many complications, worrying about space
+ layout in a future release.
