gps & gyroscope MPU6050 at a same time.

i have mega2560 i want to connect GPS & mpu6050. i get data from both when using individually ,
when i merge both code .then only gyroscope data is available. i cant read gps data in serial .
may be its getting 1 byte at a time.

here is the sketch

#include<Wire.h>
const int MPU_addr=0x68; // I2C address of the MPU-6050
int16_t AcX,AcY,AcZ,Tmp,GyX,GyY,GyZ;
void setup(){
Wire.begin();
Wire.beginTransmission(MPU_addr);
Wire.write(0x6B); // PWR_MGMT_1 register
Wire.write(0); // set to zero (wakes up the MPU-6050)
Wire.endTransmission(true);
Serial.begin(9600);
Serial1.begin(9600);
}
int red_gyro(){
Wire.beginTransmission(MPU_addr);
Wire.write(0x3B); // starting with register 0x3B (ACCEL_XOUT_H)
Wire.endTransmission(false);
Wire.requestFrom(MPU_addr,14,true); // request a total of 14 registers
AcX=Wire.read()<<8|Wire.read(); // 0x3B (ACCEL_XOUT_H) & 0x3C (ACCEL_XOUT_L)
AcY=Wire.read()<<8|Wire.read(); // 0x3D (ACCEL_YOUT_H) & 0x3E (ACCEL_YOUT_L)
AcZ=Wire.read()<<8|Wire.read(); // 0x3F (ACCEL_ZOUT_H) & 0x40 (ACCEL_ZOUT_L)
Tmp=Wire.read()<<8|Wire.read(); // 0x41 (TEMP_OUT_H) & 0x42 (TEMP_OUT_L)
GyX=Wire.read()<<8|Wire.read(); // 0x43 (GYRO_XOUT_H) & 0x44 (GYRO_XOUT_L)
GyY=Wire.read()<<8|Wire.read(); // 0x45 (GYRO_YOUT_H) & 0x46 (GYRO_YOUT_L)
GyZ=Wire.read()<<8|Wire.read(); // 0x47 (GYRO_ZOUT_H) & 0x48 (GYRO_ZOUT_L)
Serial.print("AcX = “); Serial.print(AcX);
Serial.print(” | AcY = “); Serial.print(AcY);
Serial.print(” | AcZ = “); Serial.print(AcZ);
Serial.print(” | Tmp = “); Serial.print(Tmp/340.00+36.53); //equation for temperature in degrees C from datasheet
Serial.print(” | GyX = “); Serial.print(GyX);
Serial.print(” | GyY = “); Serial.print(GyY);
Serial.print(” | GyZ = "); Serial.println(GyZ);
delay(333);
}
int red_gps(){
if (Serial1.available()) {
int inByte = Serial1.read();
Serial.write(inByte);
}

// read from port 0, send to port 1:
if (Serial.available()) {
int inByte = Serial.read();
Serial1.write(inByte);
}
}
void loop(){
red_gps();
red_gyro();
}

i want data from both 1 after another .

      delay(333);

Why? How much GPS data is going to be lost while you are doing that?

  // read from port 0, send to port 1:
  if (Serial.available()) {
    int inByte = Serial.read();
    Serial1.write(inByte);
  }

Write to the GPS? What good is THAT going to do?

With the call to red_gyro() commented out (that is NOT how to spell read), does that code work to read the GPS? In other words, is the GPS working?

your GPS data is being mixed in with you gyro data one Byte at a time...
try:

  int red_gps(){
     while(Serial1.available()) {
    int inByte = Serial1.read();
    Serial.write(inByte);
  }

PaulS gps working alright ,when using hardware serial . i have writen red just to define a function .
zhomeslice u r ri8 ,gps data is being mixed with gyro. data
i got my sketch working after i posted .
i kept the Red_gps() in for loop for 1000ms

#include<Wire.h>
const int MPU_addr=0x68; // I2C address of the MPU-6050
int16_t AcX,AcY,AcZ,Tmp,GyX,GyY,GyZ;
void setup(){
Wire.begin();
Wire.beginTransmission(MPU_addr);
Wire.write(0x6B); // PWR_MGMT_1 register
Wire.write(0); // set to zero (wakes up the MPU-6050)
Wire.endTransmission(true);
Serial.begin(9600);
Serial2.begin(9600);
}
int red_gyro(){
Wire.beginTransmission(MPU_addr);
Wire.write(0x3B); // starting with register 0x3B (ACCEL_XOUT_H)
Wire.endTransmission(false);
Wire.requestFrom(MPU_addr,14,true); // request a total of 14 registers
AcX=Wire.read()<<8|Wire.read(); // 0x3B (ACCEL_XOUT_H) & 0x3C (ACCEL_XOUT_L)
AcY=Wire.read()<<8|Wire.read(); // 0x3D (ACCEL_YOUT_H) & 0x3E (ACCEL_YOUT_L)
AcZ=Wire.read()<<8|Wire.read(); // 0x3F (ACCEL_ZOUT_H) & 0x40 (ACCEL_ZOUT_L)
Tmp=Wire.read()<<8|Wire.read(); // 0x41 (TEMP_OUT_H) & 0x42 (TEMP_OUT_L)
GyX=Wire.read()<<8|Wire.read(); // 0x43 (GYRO_XOUT_H) & 0x44 (GYRO_XOUT_L)
GyY=Wire.read()<<8|Wire.read(); // 0x45 (GYRO_YOUT_H) & 0x46 (GYRO_YOUT_L)
GyZ=Wire.read()<<8|Wire.read(); // 0x47 (GYRO_ZOUT_H) & 0x48 (GYRO_ZOUT_L)
Serial.println();
Serial.print("AcX = “); Serial.print(AcX);
Serial.print(” | AcY = “); Serial.print(AcY);
Serial.print(” | AcZ = “); Serial.print(AcZ);
Serial.print(” | Tmp = “); Serial.print(Tmp/340.00+36.53); //equation for temperature in degrees C from datasheet
Serial.print(” | GyX = “); Serial.print(GyX);
Serial.print(” | GyY = “); Serial.print(GyY);
Serial.print(” | GyZ = "); Serial.println(GyZ);
Serial.println();
delay(300);
}
int red_gps(){
for (unsigned long start = millis(); millis() - start < 1000;)
{
if (Serial2.available()) {
int inByte = Serial2.read();
Serial.write(inByte);
}

// read from port 0, send to port 1:
if (Serial.available()) {
int inByte = Serial.read();
Serial1.write(inByte);
}
}
}
void loop(){
red_gps();
red_gyro();
}

any one knows how to plot gyro data on kalman filter using processing . i have sever programs for that but non of them are working.
