Stuck with Pololu MinIMU v3

[Rec0iL]

So i have the code up and running on my arduino it prints wonderfull number like you see:

But as soon as i try to read it either with AHRSimu:

FreePIE Output.PNG

or this code:

Code: Select all

from System.IO.Ports import SerialPort
port = SerialPort("COM3", 115200)


def update():
   for text in genericCom.ReadExistingString():
      diagnostics.watch(text)

if starting:
   genericCom.update+= update

im getting this:

I really can't figure out the issue...

AHRS uses a custom binary format, your IMU needs to output in that format to work. Does the IMU support FreeIMU? In that case load it on the IMU and use the FreeIMU software, http://www.varesano.net/

The generic com plugin is only in beta status, plus you are using it wrong

Remove this (Its a raw C# SerialPort class and does not work together with Generic Com plugin)

Code: Select all

from System.IO.Ports import SerialPort
port = SerialPort("COM3", 115200)

And change the reading to this

Code: Select all

ReadLine()
def update():
   text = genericCom.readExistingString():
   diagnostics.watch(text)

You also need to get the latest Version from git

Hi CV,
Thanks for the reply
Unfortunatly it's not comatible with the FreeIMU software..

So my code looks like this right now:

Code: Select all

genericCom.ReadLine()
def update():
   text = genericCom.ReadExistingString():
   diagnostics.watch(text)

if starting:
   genericCom.update+= update

and this gives unexpected token ":" after ReadExistingString, if i remove it it gives me

if i remove genericCom. infront of ReadLine() it says read line is not defined... so i guess it's correct with the genericCom.
I'm on 1.6.152.0 pulled the latest installer or do i need to compile from source?
Thank you for the help.

Very old version, do you have possibilty to build from source?

Yes I do as a student
Will load MSVS compile and come back with more results. Thanks
