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.
