# AVR WRISTWATCH
|
|
## What is it?
|
|
This repository contains the code in development (and soon schematics) for a small wristwatch with a 128x32 OLED display. I'm hoping it will last the whole day, have cool animated visuals, and be pretty to look at.
|
|
|
|
## Desired Features and Goals
|
|
* 128x32 OLED monochrome display
|
|
* 128kb upgradable external EEPROM for images and short videos
|
|
* Fancy graphics, display images and videos that can overlay time with inverting filter
|
|
* Battery that lasts at least a day
|
|
* USB-C charging (may switch to micro-usb depending on IC prices/availability)
|
|
* Display the time
|
|
|
|
## Parts
|
|
* Microcontroller: Any ATmega chip with TWI/I2C I can get my hands on
|
|
* Display: Waveshare 128x32 0.91inch OLED display
|
|
* RTC clock: PCF85063A
|
|
* EEPROM: BR24T128-W
|
|
* Battery Management: TBD
|
|

## Why
|
|
This project is to help me learn how to develop for AVR without Arduino libraries, read datasheets faster, and to prove I can solder small SMD components. It will be my first physical project where I design my own PCB, which has been something I've wanted to do for a long time.
