+# Signal Generators Library
+
+这是一个ESP32信号生成器库，包含ECG（心电图）生成器和正弦波生成器。
+
+## 功能特性
+
+### ECG生成器 (ecg_generator)
+- 生成逼真的心电图信号
+- 可调节心率和幅度
+- 包含P波、QRS波群、T波
+- 支持实时参数调整
+
+### 正弦波生成器 (sine_generator)
+- 高频正弦波生成
+- 预计算查找表优化
+- 支持50kHz采样率
+- 内存高效设计
+
+## 使用方法
+
+### ECG生成器
+```c
+#include "ecg_generator.h"
+
+ecg_generator_t ecg_gen;
+ecg_generator_init(&ecg_gen, 250.0f);  // 250Hz采样率
+ecg_generator_set_heart_rate(&ecg_gen, 75.0f);  // 75 BPM
+ecg_generator_set_amplitude(&ecg_gen, 5.0f);    // 5mV
+ecg_generator_start(&ecg_gen);
+
+// 在定时器回调中
+float sample = ecg_generator_get_next_sample(&ecg_gen);
+```
+
+### 正弦波生成器
+```c
+#include "sine_generator.h"
+
+sine_generator_t sine_gen;
+sine_generator_init(&sine_gen, 50000.0f);  // 50kHz采样率
+sine_generator_set_frequency(&sine_gen, 200.0f);  // 200Hz
+sine_generator_set_amplitude(&sine_gen, 5.0f);    // 5mV
+sine_generator_start(&sine_gen);
+
+// 在定时器回调中
+float sample = sine_generator_get_next_sample(&sine_gen);
+```
+
+## 性能优化
+
+- ECG生成器：实时计算，适合低频应用
+- 正弦波生成器：预计算查找表，适合高频应用
+- 内存管理：自动分配和释放查找表
+- 中断友好：最小化中断执行时间
+
+## 依赖项
+
+- ESP-IDF
+- math库
+- esp_log库

+# Signal Generators Library
+
+这是一个ESP32信号生成器库，包含ECG（心电图）生成器和正弦波生成器。
+
+## 功能特性
+
+### ECG生成器 (ecg_generator)
+- 生成逼真的心电图信号
+- 可调节心率和幅度
+- 包含P波、QRS波群、T波
+- 支持实时参数调整
+
+### 正弦波生成器 (sine_generator)
+- 高频正弦波生成
+- 预计算查找表优化
+- 支持50kHz采样率
+- 内存高效设计
+
+## 使用方法
+
+### ECG生成器
+```c
+#include "ecg_generator.h"
+
+ecg_generator_t ecg_gen;
+ecg_generator_init(&ecg_gen, 250.0f);  // 250Hz采样率
+ecg_generator_set_heart_rate(&ecg_gen, 75.0f);  // 75 BPM
+ecg_generator_set_amplitude(&ecg_gen, 5.0f);    // 5mV
+ecg_generator_start(&ecg_gen);
+
+// 在定时器回调中
+float sample = ecg_generator_get_next_sample(&ecg_gen);
+```
+
+### 正弦波生成器
+```c
+#include "sine_generator.h"
+
+sine_generator_t sine_gen;
+sine_generator_init(&sine_gen, 50000.0f);  // 50kHz采样率
+sine_generator_set_frequency(&sine_gen, 200.0f);  // 200Hz
+sine_generator_set_amplitude(&sine_gen, 5.0f);    // 5mV
