My project will be a game coded completely in rust designed to run on a Pico 2W with 8 buttons (Left, Right, Up, Down, A, B, C and D), Temp Sensor, Accel Sensor.
I chose this project because I decided to implement a multiple features and utilize all aspects I've studied up until now in the lab, in rust on a microprocessor like the Pico 2W.
Raspberry Pi Pico 2W to:
- RGB_TFT LCD Screen 128x160
- A, B, C, D buttons
- Left, Right and Up, Down buttons
- Buzzer
- Temperature Sensor
- Acceleration Sensor
Established main board connections. Connected debugger, main board, a b c d buttons, screen and buzzer. Wrote code to initialize and test functionality for these. Wrote a script to display chroma keyed sprites on the screen so I can use background images and one to play sounds for the buzzer.
Purchased sensors. Scrapped joystick and replaced with buttons.
Established connections between the rest of the components.
Named the game RogueRust. LithTheFox from the boot screen is my alias.
Chose new sensors, initialized accel sensor but it is unable to read properly
Created main game loop, character sprites, creatures as well as gameplay base off this.
The final board being:
Raspberry Pi Pico 2W, Buttons, Screen (rgb_tft 128x160), Temperature Sensor, Acceleration Sensor.
