حل شده gy87

با سلام و احترام
ماژول gy-87 را خریداری کردم و از کتابخانه های bmp180 , hmcl5583l , mpu6050 , I2Cdev استفاده کردم
gy87 libraryلینک دانلود کتابخانه ها
, توسط کد زیر برنامه را اجرا کردم،توسط آردینو uno R3
زمان استارت برنامه مینویسه که bmp180 شناسایی نشد
لطفا اگر جایی از کار بنده ایراد دارد راهنمایی بفرمایید
با تشکر

GY87_Readerv0.ino

This sketch is based on various sketches and libraries by Jeff Rowberg

<jeff@rowberg.net> and discussion thread by pistolero992000 on the Arduino forum

https://forum.arduino.cc/index.php?topic=223345.0.  The BMP180 pressure

Senor library is from Love Electronics Ltd (loveelectronics.com)

http://embedded-lab.com/blog/bmp180/bmp180_11/



It gets all sensors on a GY87 IMU board reporting (something) to the

Serial.  The challenge is the Digital Compass which is nromally blocked by

the Accelerometer.  This is remedied by using an I2C bypass command.  Thanks to

pistolero992000 for this solution.



Sensors on board the GY87 are:

MPU6050 Accelerometer.  Address is 0x68

HMC5883L Digital Compass.  Address is 0x1E

BMP180 Barometer and Temperature Sensor.  Address is 0x77



Connections are through the i2c bus.



SCL to Arduino Pin A5

SDA to Arduino Pin A4

GND, 5V and 3.3V connections also present.



All sensors report sensible values.  The tab seperated data covers a lot of screen space

so you will need to stretch your Serial monitor window to accommodate it.
