我使用Serial.print（）函数通过arduino的串口传输flex传感器值，但是我无法在接收端读取它

Question

实际上在我的代码中我传输加速度计值以及4个弹性传感器值。我已将加速度计值转换为4状态，如F（前进），B（后退），R（右），L（左）。我能够收到这4个状态，并且我能够为这些状态编写代码。在这些状态下，我还发送了柔性传感器值来远程控制伺服电机。但是我无法读取这些弹性值，因为它是一个变化的整数。请帮我看一下flex值。我尝试过Serial.read（），Serial.parseInt（）。

我的发射器代码是：

int xpin = A0;
int x;
int ypin = A1;
int y;
int vcc=13;

const int flexpin1 = 2;
const int flexpin2 = 3;
const int flexpin3 = 4;
const int flexpin4 = 5;

int flex1[20];
int flex2[20];
int flex3[20];
int flex4[20];

int flexsum1=0;
int flexsum2=0;
int flexsum3=0;
int flexsum4=0;

 char state1 = 'S';
void setup() {

  // put your setup code here, to run once:
  Serial.begin(115200);

  pinMode(flexpin1, INPUT);
  pinMode(flexpin2, INPUT);
  pinMode(flexpin3, INPUT);
  pinMode(flexpin4, INPUT);
  pinMode(xpin, INPUT);
  pinMode(ypin, INPUT);
  pinMode(vcc, OUTPUT);
  digitalWrite(vcc, HIGH);
}

void loop() {


  x = analogRead(xpin);
  Serial.print("xpin=");
  Serial.print(x);
  y = analogRead(ypin);
  Serial.print("\t ypin=");
  Serial.print(y);
  if ( y > 415)
  {
    state1 = 'F';
  }
  else if (y < 315)
  {
    state1 = 'B';
  }
  else if (x > 410)
  {
    state1 = 'R';
  }

  else if (x < 310)
  {
    state1 = 'L';
  }

  else {
    state1 = 'S';
  }

 // flex readings stabelized//


for(int x=0; x<25; x++)
{
flex1[x]=analogRead(flexpin1);
flex2[x]=analogRead(flexpin2);
flex3[x]=analogRead(flexpin3);
flex4[x]=analogRead(flexpin4);
flexsum1=flexsum1+flex1[x];
flexsum2=flexsum2+flex2[x];
flexsum3=flexsum3+flex3[x];
flexsum4=flexsum4+flex4[x];

delayMicroseconds(20);
}
flexsum1=flexsum1/25;
flexsum2=flexsum2/25;
flexsum3=flexsum3/25;
flexsum4=flexsum4/25;



  Serial.print("\t\t\tflexsum1= ");
  Serial.print(flexsum1);

  Serial.print("\tflexsum2= ");
  Serial.print(flexsum2);

  Serial.print("\tflexsum3= ");
  Serial.print(flexsum3);

  Serial.print("\tflexsum4= ");
  Serial.print(flexsum4);

  Serial.print("\t state1=");
  Serial.println(state1);

delay(200);
  }

我收到的代码：
