From the project
Real-time cricket batting game on the TI MSPM0G3507 (ARM Cortex-M0+) with triple-ISR architecture, custom KiCad PCB, 5-bit DAC audio, and 3D-printed enclosure. Built for ECE 319H at UT Austin.
CrickHit is a real-time cricket batting game built from scratch on the TI MSPM0G3507 LaunchPad with a ST7735R 128x160 TFT LCD. The player controls a batsman using a slide potentiometer and physical switches to hit balls bowled with realistic curve trajectories. The game runs entirely on bare-metal interrupts with no RTOS, using fixed-point physics, sprite compositing, a custom 5-bit binary-weighted DAC for audio, and multilingual UI support.
