使用 T5AI-Core 快速搭建 AI 聊天机器人

概述

首先，请参考 T5AI-Core 开发套件 了解 T5AI-Core 的详细信息。

T5AI-Core 和 ST7789 屏幕的引脚接线定义如下（和 EVB 相同）：

效果图：

配置 menuconfig

1. 首先，请参考 下载并激活 TuyaOpen 激活 tos.py。

2. 在终端中输入 cd apps/tuya.ai/your_chat_bot && tos.py config menu 并运行，然后按照下图所示，根据您的实际需求在代码中修改配置信息。

   

   

   

代码修改

在屏幕字体初始化接口中增加 T5AI-Core 定义

1. 找到 apps/tuya.ai/your_chat_bot/src/display/app_display.c 文件中的 get_ui_font 接口。

2. 在如下图所示的位置，增加 || BOARD_CHOICE_TUYA_T5AI_CORE 代码。

   

填写授权码

找到 apps/tuya.ai/your_chat_bot/include/tuya_config.h 文件，将授权码（UUID 和 Authkey）分别填写到 TUYA_OPENSDK_UUID 和 TUYA_OPENSDK_AUTHKEY 两个宏定义中，如下图所示：

添加显示屏驱动

在 TuyaOpen/boards/T5AI/TUYA_T5AI_CORE/tuya_t5ai_core.c 文件中添加显示屏驱动的代码，可以复制下方代码并完全替换您的原代码。

编译烧录

在终端中输入 tos.py build && tos.py flash 并运行。

开发版有两路串口，一路用于烧录固件，一路用于日志打印，请尝试并按需选择，如下图所示：

烧录运行，正常运行结果如下图所示：

日志监控

在终端中输入 tos.py monitor 并运行，如下图所示：
