CPU utilisation is very high #392

Have you done any profiling to figure out what is causing the utilization to run high? Would you mind replacing

Thank you for your response and guidelines. However, the problem still persists. I have edited the code as per your suggestions and provided the updated code below. Additionally, I checked the CPU utilization using 'htop' in a Linux environment. Here are the results of the CPU utilization before and during the execution is provided here |
Dear msclissa
Please offer a proper solution for this .
I contacted your team regarding very high CPU utilization, but I have not
received a proper solution. I also posted the issue in the Git repository
along with the program.
Currently, I am trying to acquire data using the DCP manual for the
3DM-GX5-25 AHRS sensor. Could you please provide the commands or a sample
program to acquire roll, pitch, and yaw data from the sensor?
Thank you.

subsequent loop with
# look at how many packets node.getDataPackets() usually returns, probably averaged over a couple iterations
EXPECTED_PACKETS = 1
for i in range(EXPECTED_PACKETS):
data_points.append(["0.0", "0.0", "0.0"])
Also, remove
node = DisplacementNode(connection)
to prevent continuous data collection and buffering.
Is CPU utilization still high when MSCL is removed from the equation?
Leaving the CSV open and just writing to it every loop instead of
re-opening it every loop might also help?
A quick aside, I would recommend using InertialNode instead of
DisplacementNode - it won't make a difference in this scenario because
they use the same parser and getDataPackets() function, but InertialNode
will have all the command interface functions your device supports.

I am running Python code to extract Roll, Pitch, and Yaw from a Microstrain 3DM-GX5-AHRS and store the data with timestamps. However, running this code consumes more than 90% of the CPU. How can I optimize and reduce the CPU utilization?
my system details.
Operating System: Ubuntu Mint 20.04
Software: Python 3
Hardware: Intel Atom Dual Core Processor SBC
RAM: 8 GB
Storage: 64 GB SSD
