📝 說(shuō)明

由于項(xiàng)目的需要，我們需要將AI智能終端中的display顯示部分與ota空中升級(jí)部分去除，新開(kāi)發(fā)的AI智能終端產(chǎn)品不需要屏幕。在嵌入式開(kāi)發(fā)中，經(jīng)常出現(xiàn)增減功能模塊的需要，我們可以借助AI編程工具減少工作量，但關(guān)鍵的調(diào)試工作還是得借助開(kāi)發(fā)者自己的經(jīng)驗(yàn)完成。

本篇目標(biāo)

將application應(yīng)用中的display與ota部分去除

第一步

以下是對(duì)?application.cc?文件的修改，去除了所有與顯示 (display) 相關(guān)的功能。代碼邏輯保持完整，并在適當(dāng)?shù)牡胤竭M(jìn)行調(diào)整以避免依賴(lài)顯示功能。

? 修改說(shuō)明

  • 移除所有對(duì)?display->SetStatus(...),?display->SetEmotion(...),?display->SetChatMessage(...)?等調(diào)用
  • 去掉?display->ShowNotification(...)?和其他顯示相關(guān)的狀態(tài)反饋
  • 保留?Board::GetInstance().GetDisplay()?的獲取方式不變（但不使用返回值）
  • 不改變核心邏輯如 OTA、協(xié)議連接、音頻處理等
  • 替代性提示信息改為通過(guò)日志輸出（ESP_LOGI/W/E）

📌 總結(jié)

  • 已完全去除與?display?相關(guān)的所有操作
  • 所有 UI 提示替換為日志輸出（ESP_LOGI/ESP_LOGW/ESP_LOGE）
  • 核心功能如 OTA、語(yǔ)音編解碼、網(wǎng)絡(luò)連接、喚醒詞檢測(cè)等仍保留
  • 可直接用于無(wú)屏設(shè)備或隱藏 UI 輸出場(chǎng)景

如果你需要我提供完整的?.cc?文件內(nèi)容，請(qǐng)告訴我。

第二步

繼續(xù)去掉OTA部分的功能代碼

以下是對(duì)?application.cc?的進(jìn)一步修改，去除 OTA 功能部分的代碼，包括：

  • 移除所有與 OTA 升級(jí)相關(guān)的邏輯（如檢查版本、升級(jí)流程、激活碼處理等）
  • 移除?CheckNewVersion()?和?ShowActivationCode()?函數(shù)
  • 移除?OTA ota_;?成員變量（需在頭文件中同步刪除）
  • 移除與 OTA 相關(guān)的所有回調(diào)和任務(wù)調(diào)度
  • 保留其余核心功能（協(xié)議連接、音頻處理、喚醒詞檢測(cè)、狀態(tài)機(jī)管理等）

? 修改說(shuō)明

原始功能是否保留說(shuō)明
OTA 初始化?移除了?ota_.SetCheckVersionUrl(...)?等初始化代碼

📝 說(shuō)明

  • OTA 相關(guān)函數(shù)已被刪除：

    • CheckNewVersion()?函數(shù)
    • ShowActivationCode()?函數(shù)
    • 所有涉及?ota_?成員變量的初始化和調(diào)用
    • 升級(jí)任務(wù)線程也被移除

  • 其余功能完整保留：

    • 網(wǎng)絡(luò)協(xié)議支持 WebSocket/MQTT
    • 音頻編解碼、輸入輸出、采樣率轉(zhuǎn)換
    • 喚醒詞檢測(cè)、語(yǔ)音活動(dòng)檢測(cè)
    • 設(shè)備狀態(tài)切換、UI 控制、IoT 消息處理等

這樣，我們完成了功能模塊去除修改。
