Filter 消除CC3200上传感器读数的噪音？

一步一步我到目前为止做了什么

1） 微控制器采用德克萨斯仪器公司的CC3200（wifi内置微控制器） 2） 导电橡胶线拉伸传感器-连接到微控制器的模拟引脚 **传感器行为=（拉伸导电橡胶时电阻增加）

现在，下面是我调试到微控制器以运行传感器的参考代码（使用energia工具IDE）。 代码只不过是为web服务器编写的（我提供了可用的wifi ssid和密码，您可以在下面的程序“iPhone和passowrd”中看到），传感器的代码也被写入其中

该Web服务器读取并生成微控制器的IP地址以及拉伸传感器的值

Web服务器代码：

#include <SPI.h>
#include <WiFi.h>
#include <WiFiClient.h>
#include <WiFiServer.h>
// which analog pin to connect
#define RUBBERPIN A3

// how many samples to take and average, more takes longer
// but is more 'smooth'
#define NUMSAMPLES 5
// the value of the 'other' resistor
#define SERIESRESISTOR 10000
int samples[NUMSAMPLES];

// your network name also called SSID
char ssid[] = "iPhone";
// your network password
char password[] = "123456789";
// your network key Index number (needed only for WEP)
int keyIndex = 0;

WiFiServer server(3000);

void setup() {
Serial.begin(115200);      // initialize serial communication
analogReference(EXTERNAL);
pinMode(RED_LED, OUTPUT);      // set the LED pin mode

// attempt to connect to Wifi network:
Serial.print("Attempting to connect to Network named: ");
// print the network name (SSID);
Serial.println(ssid); 
// Connect to WPA/WPA2 network. Change this line if using open or WEP      
network:
WiFi.begin(ssid, password);
while ( WiFi.status() != WL_CONNECTED) {
// print dots while we wait to connect
Serial.print(".");
delay(300);
 }

 Serial.println("\nYou're connected to the network");
 Serial.println("Waiting for an ip address");

  while (WiFi.localIP() == INADDR_NONE) {
 // print dots while we wait for an ip addresss
 Serial.print(".");
 delay(300);
  }

  // you're connected now, so print out the status  
   printWifiStatus();

  Serial.println("Starting dataerver on port 3000");
  server.begin();                           // start the web server on port        
  80
  Serial.println("Dataserver started!");

  }


void loop() {
// listen for incoming clients
WiFiClient client = server.available();
if (client) {
Serial.println("new client");
// an http request ends with a blank line
boolean currentLineIsBlank = true;
while (client.connected()) {
  uint8_t i;
float average;
// take N samples in a row, with a slight delay
for (i=0; i< NUMSAMPLES; i++) {
samples[i] = analogRead(RUBBERPIN);
delay(10);
}
// average all the samples out
average = 0;
for (i=0; i< NUMSAMPLES; i++) {
average += samples[i];
}
average /= NUMSAMPLES;
Serial.println(average);

  client.println(average);
  delay(10);
}
delay(1);
// close the connection:
client.stop();
Serial.println("client disonnected");
 }
}


void printWifiStatus() {
// print the SSID of the network you're attached to:
Serial.print("Network Name: ");
Serial.println(WiFi.SSID());

// print your WiFi shield's IP address:
IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");
Serial.println(ip);

// print the received signal strength:
long rssi = WiFi.RSSI();
Serial.print("signal strength (RSSI):");
Serial.print(rssi);
Serial.println(" dBm");
  }

运行以下程序后的结果：

服务器发送数据，客户端以无线方式接收数据——一切正常 我能够看到我期望的输出信号。i、 例如，当我的传感器处于静止位置时，输出必须是直线，如果我拉伸传感器，电压信号必须增加-我能够看到所有这些。但是,

这里有一个小问题

输出信号发出噪声（请查看下图）

所以我的问题是，即使传感器处于静止位置——没有任何拉伸——也会出现峰值

请先格式化您的代码。首先，代码闻起来很像，而且无论如何都不是这样的。与硬件相关的东西，或者至少与信号数字滤波器有关。这不是C代码！语言正确。请先格式化你的代码。首先，代码闻起来很像，而且无论如何都不是这样的。与硬件相关的东西，或者至少与信号数字滤波器有关。这不是C代码！使语言正确。
