In reply to satya. How u do u get the normal condition? Because mine when it is static. The angle doesnt behaves as it is. The angular rate should be 0. But i didnt get zero values on angular rate x, y and z. Can you help me with this?

In reply to Mar. Yeah, I think the Two Wire Baud Rate (TWBR) register is used only on Atmega micro-controllers; this code is quite old so many of the newer Arduino boards weren't available at the time (I published this post in 2015). I think in new versions of Arduino, the "Wire.setClock(400000);" command is used instead. I'll update the code to remove that line.

i doubt that anyone can use that TWBR anymore,i searched in the I2Cdev file,is nothing of that in it,maybe it was long ago,but is not anymore,so i guess that now we all just gonna delete that line… with it i just get the error : that TWBR wa snot define..,or something like that…

In reply to TheBluem. Just remove or comment out the line; without it the default I2C clock speed will be used.

int TWBR = 24; // 400kHz I2C clock (200kHz if CPU is 8MHz)
^~
exit status 1
lvalue required as left operand of assignment

I just get this error how could I fix it?

hi,
it is just the same code but on mega 2560 the I2C conection is just on different pins,
SDA = Digital pin 20
SDL = Digital pin 21
INT = Digital pin 2 (if you didn’t changed it in the I2Cdev library)

Hello,
Please send me mpu 6050 calibration code using Arduino mega 2560

hello,
please, how to deal with the over flow problem
I want to get yaw angle every 100 ms, but here I get a problem of buffer overflow

Thank you for ur reply and for the great work u done.
I’ve bought an IMU mpu9250 wich contain a compass
but I didn’t found the code to get the yaw angle, can u please help me ?
thank u again.
