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.
