Detailed Description

Firmware for the LCC Fusion Sound Card.

High-level overview and links to the main entry points (setup/loop) and helper functions used by the Sound firmware.

Enumeration Type Documentation

◆ requestTypes

enum requestTypes

Request types for sound commands via serial/I2C.

Enumerator
PLAY	Start playback of specified file.
LOOP	Loop playback indefinitely.
PAUSE	Pause current playback.
RESET	Reset the DFPlayer device.
NONE	No request.

Variable Documentation

◆ I2C_ADDR_OFFSET_PIN_SET

constexpr uint8_t I2C_ADDR_OFFSET_PIN_SET[3] = { 34, 35, 32 }

staticconstexpr

GPIO pins used for I2C address selection DIP switches.

Each pin contributes a bit (pin1=+1, pin2=+2, pin3=+4) relative to base address. These pins must be configured with internal pull-ups; DIP switch grounds pin when closed.

Definition at line 67 of file config.h.

◆ SW_SERIAL_PIN_SET

constexpr uint8_t SW_SERIAL_PIN_SET[NUM_PLAYERS_PER_CARD][2]

staticconstexpr

Initial value:

= {
  { 22, 23 },  
  { 21, 19 },  
  { 17, 16 },  
  { 2, 15 }    
}

SoftwareSerial pin mappings for each DFPlayer.

For each entry [i], the first value is ESP32 RX pin (DFPlayer TX → ESP32), the second value is ESP32 TX pin (ESP32 → DFPlayer RX).
