### 使用单片机生成正弦波和三角波 #### 正弦波生成方法及代码示例 为了在单片机上生成正弦波,通常采用查法或实时计算的方式。查法预先存储一组代正弦函数值的数据,在运行时通过定时中断或其他方式依次读取这些数据并输出到DAC转换成模拟电压。 对于Arduino UNO平台上的实现如下所示: ```cpp const int sineWavePin = 9; // 定义PWM引脚用于输出正弦波 float amplitude = 127.5; float offset = 127.5; // 预先定义好的正弦查找 byte sinetable[]={ 0, 8, 16, 23, 31, 38, 45, 52, 58, 64, 69, 74, 78, 81, 84, 86, 88, 89, 90, 90, 90, 90, 89, 88, 86, 84, 81, 78, 74, 69, 64, 58, 52, 45, 38, 31, 23, 16, 8, 0, 255-8, 255-16, 255-23, 255-31, 255-38, 255-45, 255-52, 255-58, 255-64, 255-69, 255-74, 255-78, 255-81, 255-84, 255-86, 255-88, 255-89, 255-90, 255-90, 255-90, 255-90, 255-89, 255-88, 255-86, 255-84, 255-81, 255-78, 255-74, 255-69, 255-64, 255-58, 255-52, 255-45, 255-38, 255-31, 255-23, 255-16, 255-8}; void setup() { pinMode(sineWavePin, OUTPUT); } int index = 0; void loop(){ analogWrite(sineWavePin,sinetable[index]); delay(1); if (index >= sizeof(sinetable)-1){ index=0; }else{ ++index; } } ``` 这段代码展示了如何利用预存的正弦格来生成近似的正弦波形[^1]。 #### 三角波生成方法及代码示例 同样地,也可以创建一个示三角波形状数值序列,并按照一定频率更新该序列中的每一个元素至指定IO端口以形成所需的波形。下面给出的是针对相同硬件环境下的简单例子: ```cpp const int triangleWavePin = 10; // 定义PWM引脚用于输出三角波 unsigned char triTable[256]; void setup() { pinMode(triangleWavePin, OUTPUT); // 初始化三角波数组 for(int i=0;i<128;i++){ triTable[i]=i*2; triTable[255-i]=255-(i*2); } } unsigned int pos = 0; void loop(){ analogWrite(triangleWavePin,triTable[pos]); delayMicroseconds(1000); if(pos>=255){ pos=0; } else { pos++; } } ``` 此段代码实现了基本的三角波输出逻辑,其中`delayMicroseconds()`用来控制波形周期长度从而改变其频率特性。
