AngryBirds with AT89S52 and OLED

This project involves an AT89S52 chip and a KT89S51 board to create an AngryBirds game. The communication between the components is facilitated through UART, and a visual presentation is achieved with an OLED display.

System Stucture

Circuit Diagram

1. The minimum ciruit to run the AT89S52 chip.

2. The ciruit for communication between two chips using UART

Note

Note that this is a bit tricky. In my case, I have to connect TX to TX and RX to RX, then it can work. Don't figure out why...

3. The ciruit for communication from two chips to an OLED using I2C

Note

Only one microcontroller can control the OLED at a time. Initiate the start condition signal for control and send the stop condition signal to discontinue I2C usage.

4. The ciruit using two chips to jointly control five buttons for the game
