我来帮你设计一个基于ESP32-S3的AI语音助手实现方案。这个项目可以分为几个主要部分:
硬件需求:```ESP32-S3开发板INMP441或MSM261等I2S麦克风MAX98357A或类似I2S DAC音频放大器扬声器(可选)显示屏,如SSD1306 OLED```
基础代码架构:
#include <Arduino.h> #include <WiFi.h> #include <HTTPClient.h> #include <driver/i2s.h> #include <ArduinoJson.h> // WiFi配置 const char* ssid = "YOUR_WIFI_SSID"; const char* password = "YOUR_WIFI_PASSWORD"; // I2S配置 #define I2S_WS_MIC 18 #define I2S_SCK_MIC 17 #define I2S_SD_MIC 16 #define I2S_WS_SPEAK 5 #define I2S_SCK_SPEAK 4 #define I2S_SD_SPEAK 3 // I2S麦克风配置 void setupMicrophone() { i2s_config_t i2s_config = { .mode = (i2s_mode_t)(I2S_MODE_MASTER | I2S_MODE_RX), .sample_rate = 16000, .bits_per_sample = I2S_BITS_PER_SAMPLE_32BIT, .channel_format = I2S_CHANNEL_FMT_ONLY_LEFT, .communication_format = I2S_COMM_FORMAT_STAND_I2S, .intr_alloc_flags = ESP_INTR_FLAG_LEVEL1, .dma_buf_count = 4, .dma_buf_len = 1024, .use_apll = false }; i2s_pin_config_t pin_config = { .bck_io_num = I2S_SCK_MIC, .ws_io_num = I2S_WS_MIC, .data_out_num = I2S_PIN_NO_CHANGE, .data_in_num = I2S_SD_MIC }; i2s_driver_install(I2S_NUM_0, &i2s_config, 0, NULL); i2s_set_pin(I2S_NUM_0, &pin_config); } // I2S扬声器配置 void setupSpeaker() { i2s_config_t i2s_config = { .mode = (i2s_mode_t)(I2S_MODE_MASTER | I2S_MODE_TX), .sample_rate = 16000, .bits_per_sample = I2S_BITS_PER_SAMPLE_16BIT, .channel_format = I2S_CHANNEL_FMT_ONLY_LEFT, .communication_format = I2S_COMM_FORMAT_STAND_I2S, ...
