This project aims to create a digital piano using the TM4C-123 microcontroller. The project uses various hardware components and software functions to achieve this. The piano has different modes like "Piano Mode" and "Auto-Play Mode" which can be toggled using onboard switches.
- 6-bit DAC for sound generation.
- Piano keys mapped to GPIO pins.
- Different modes for manual and auto-playing.
- Interrupt-based architecture for real-time performance.
- TM4C-123 microcontroller
- 6-bit DAC
- Onboard switches and LEDs
Responsible for initializing onboard switches and LEDs. It also controls the current mode of the piano.
ButtonLed_Init(): Initialize the switches and LEDs.get_current_mode(): Get the current mode of operation.
Handles all the sound-related functionalities like initializing the DAC, playing notes, and songs.
Sound_Init(): Initialize the sound system.Sound_Start(): Start playing a note.Sound_stop(): Stop playing a note.
Main file where all initializations and main loop reside.
main(): Main function where the program starts.
Assembly file for low-level initializations and configurations.
DisableInterrupts(): Disable all interrupts.EnableInterrupts(): Enable all interrupts.WaitForInterrupt(): Go to low power mode while waiting for the next interrupt.
- Compile all the source and header files.
- Flash the compiled program onto the TM4C-123 microcontroller.
- Interact with the piano using the onboard switches to change modes and play notes.
