This is a tiny little project I made to get my own Virtual Pet. I hope you like it as much as I do. /n The code can receive some optimiztion, so feel free to change it as you like. /n I would be glade to see your project too if you choose to make one pet by yourself. /n Thank you! /n

HARDWARE:

STM32 F103C8T6 (Blue Pill); (It demands at least 3.5KB RAM and 32KB ROM)
1.3" OLED I2C Screen 128x64;
4 push buttons (with 1n4148 diode to prevent debounce);

WIREING: I Used the pins PA9, PA10, PA11, PA12 for all the buttons, and used a diode n4048 to prevent debounce. The OLED display was wired at I2C1 (PB7 and PB8 for SDA and CLK).
