pyb library?

[kswain1]

I am having a problem importing the pub library where I can I find it. Tried using pip, and didn't have any luck.

[kswain1]

I'm using python 2.7, and I'm not using a micro python board. I am using OS X YOSEMITE to filter information.

[kswain1]

I only need the pyb module to complete this method Integrate to yield quaternion. Is there any other way I can do the integration with another module besides pyb? These two are the methods

• deltat = pyb.elapsed_micros(self.start_time) / 1000000
• self.start_time = pyb.micros()

You will have to replace the pyb calls with calls to time or datetime.

pyb.micros() is the time in microseconds
pyb.elapsed_micros(arg) gives the elapse time in micros since arg

[kswain1]

Yes I have added the time function to instead of pyb.
Do you know if this is similar function to pyb micros

import time
def micros():
return time.time()/1000000

def elapsed_micros(start_time):
return time.time()/1000000 - start_time

If so, I am currently getting all zero's for my yaw, pitch, and roll,which is definitely wrong.
What are some average angles to expect?

time.time() returns seconds so you need to multiply by 1000000 to get microseconds rather than divide.

Thank you will try it in the next couple of hours to let you know the results, so we can close this issue.

Hi I won't have my computer until the end of the month... But I was looking at getting the IMU code working in python3 with a mpu6050. Like you I struggled to find the pyb library. Hope it works for you.

Hey I believed the solutions works! I am getting results, but my next question is for the calibration function during the initial time does the algorithm start the position at (0,0,0) until the chip is moved? If so I am having problems with the calibration portion of the algorithm.

Make sure to share your patches.

[kswain1]

I believe everything is working. Patch Update
import time
def micros():
return time.time()*1000000

def elapsed_micros(start_time):
return time.time()*1000000 - start_time

replace these functions with pyb, and you should be ok.
