Incompatible with SD.h: Status: -20

[sidbanch]

When I run the Basic I2C test, it displays the values from the sensor (even with the SD card plugged in, it works) If I import both libraries (this one and SD.h), then it fails to begin the MPU. Here is the code (I tried with and without Wire.h; if I use &Wire, the constructor doesn't work (same TwoWire error someone else was getting):

`

include "MPU9250.h"

include "Wire.h"

// an MPU9250 object with the MPU-9250 sensor on I2C bus 0 with address 0x68 MPU9250 IMU(Wire,0x68); int status;

include

BMP280_DEV bmp280; float temperature, pressure, altitude;

include "SD.h"

char filename[] = "LOGGER00.TXT"; const int chipSelect = 10; // the logging file File logfile;

void setup() { // serial to display data Serial.begin(115200); while(!Serial) {}

// start communication with IMU Serial.println("IMU"); status = IMU.begin(); if (status < 0) { Serial.println("IMU initialization unsuccessful"); Serial.println("Check IMU wiring or try cycling power"); Serial.print("Status: "); Serial.println(status);

} Serial.println("BMP"); bmp280.begin(BMP280_I2C_ALT_ADDR); bmp280.setTimeStandby(TIME_STANDBY_05MS); bmp280.startNormalConversion();

Serial.println("Initializing SD card..."); pinMode(10, OUTPUT);

// see if the card is present and can be initialized: if (!SD.begin(chipSelect)) { Serial.println("Card failed, or not present"); // don't do anything more: return; } Serial.println("card initialized.");

// create a new file

for (uint8_t i = 0; i < 100; i++) { filename[6] = i/10 + '0'; filename[7] = i%10 + '0'; if (! SD.exists(filename)) { logfile = SD.open(filename, FILE_WRITE); break; // leave the loop! } }

if (! logfile) { Serial.println("couldnt create file"); }

Serial.println("Logging to: "); Serial.println(filename);

logfile.close();

logline("Accel X, Accel Y, Accel Z, Gyro X, Gyro Y, Gyro Z, Temp (Celsius), Pressure (hPa), Altitude (m)"); }

void loop() {

if (bmp280.getMeasurements(temperature, pressure, altitude)) // Check if the measurement is complete { // read the sensor IMU.readSensor(); // display the data

String s = "";
s += String(millis());
s += ", ";
s += String(IMU.getAccelX_mss());
s += ", ";
s += String(IMU.getAccelY_mss());
s += ", ";
s += String(IMU.getAccelZ_mss());
s += ", ";
s += String(IMU.getGyroX_rads() * 57.2957795);
s += ", ";
s += String(IMU.getGyroY_rads() * 57.2957795);
s += ", ";
s += String(IMU.getGyroZ_rads() * 57.2957795);
s += ", ";
s += String(temperature); 
s += ", ";
s += String(pressure);
s += ", ";
s += String(altitude); 
logline(s);

}

}

void logline(String s) { Serial.println(s); logfile = SD.open(filename, FILE_WRITE); logfile.println(s); logfile.close(); }`
