前不久，@云天在 DF创客社区论坛发了一个“能听会说的小车”雏形，但只用了行空板K10的四个引脚。
这次云天老师把金手指引出的“引脚”通过IO扩展板接入 3个L298N（DF-MD V1.3）电机驱动器，控制小车真正做到了“说一句，动一路”——前进、后退、左转、右转、机械臂 360° 旋转、抬起放下、机械爪张合，全部一条语音指令搞定。

软件关键片段
1. IO 扩展板一次初始化
uint16_t output_pins = (1 << 8) | (1 << 9) | (1 << 12) | (1 << 13) | (1 << 14) | (1 << 3) | (1 << 4) | (1 << 2) | (1 << 7);
esp_io_expander_set_dir(io_expander, output_pins, IO_EXPANDER_OUTPUT);
esp_io_expander_set_level(io_expander, output_pins, 0); // 全部归零，防止上电乱动

把 12 条动作全部写进一个 Lambda，LLM 只需一次函数调用即可精准执行。
3. 停车回调函数
static void StopMotorCallbackStatic(TimerHandle_t xTimer) {
auto* self = static_cast<Df_K10Board*>(pvTimerGetTimerID(xTimer));
self->StopMotorCallback();
}
void StopMotorCallback() {
SetPnumLevel(8, 0);
SetPnumLevel(9, 0);
SetPnumLevel(12, 0);
SetPnumLevel(13, 0);
SetPnumLevel(14, 0);
SetPnumLevel(3, 0);
SetPnumLevel(2, 0);
SetPnumLevel(7, 0);
SetPnumLevel(4, 0);
}
每条动作都会根据实际行程重置定时器（爪 1.6 s、臂 0.8~1 s、底盘 1 s），兼顾“到位”与“安全”。
一句话总结
“当语音助手不再只是‘聊天’，而是能直接操作 5 路电机、11 种动作、100% 开源可二次开发，你会发现——给 ESP32 装上‘大模型’，才是嵌入式玩家的新浪漫。”
