About

This project tries to be the smallest implementation of Google's easter egg T-Rex Runner with resolution of only 128x32px.

The goal is to make a small game console by using Atmels Atmega88 microcontroller and SSSD1306 oled display.

Schematic & PCB

Made with AUTODESK EAGLE 9.0.0

3D model

Made with FreeCAD 0.18

DM DIY-MORE OLED-091

Popular I2C OLED 32x128 display from diy-more has an issue. It doesn't properly start after power on, but starts without problems after reset. To solve this problem swap R3 and R4 resistors.

make hex

Flashing the MCU

Before flashing set up the AVR programmer by changing the value of PROGRAMMER variable in firmware/Makefile. By default it is set to usbasp.

PROGRAMMER = usbasp

To flash fuses, firmware and eeprom:

cd firmware
make program

To flash firmware only:

cd firmware
