Project Title

Ace Mario

Abstract

Super Mario is one of the best-selling games of all time, with more than 50 million copies sold worldwide. Our goal will be to produce a similar version of it where the player controls Mario. Mario has to race through the Mushroom Kingdom and save Princess.

MP3 Decoder

The MP3 player device which is based on a high-quality MP3 audio chip -YX5300 is used in our project to play different soundtracks based on the current state of the game such as jump, victory, game over and Mario run states. Our master controller unit (sjtwo-c board) controls MP3 playback state by sending commands to serial MP3 via UART port

Bluetooth Interface

For this project, we used two HC-05 Bluetooth modules. One Bluetooth was configured on the LED matrix controller board while the other was configured on the gamepad controller. The Bluetooth configured on the led matrix controller worked as a slave, only receives commands, while the one configured on the gamepad worked as master, sending controls to the other controller. The master Bluetooth connected to the gamepad controller transmitted the joystick direction. The transmitted direction was in the form of x and y coordinates. The UP and FORWARD direction was calibrated using the x and y coordinates. So along with UP and FORWARD direction, the joystick switch button data was also transmitted using Bluetooth.

We selected the HC-05 Bluetooth module to transmit data over other modules because of their ease to configure, they are extremely reliable and also easy to set up. Both the Bluetooth modules were configured using AT commands. Using AT commands made our job easy to set one Bluetooth as a master while the other as a slave. The best thing about using AT commands is that we can change the configuration as per our needs. The UART baud rate was set to 38400.
