the power of myrio is not enough

Hello,
iam using myrio and i have connected with many sensors like: (GPS,Compass,usb camera,LiDAR, Motor Driver )
usb camera and the liDAR connected via usb Hub ,
so when i run a code that acquire data from all of these sensors the myrio start disconnect , keep giving me waiting myrio to response .

so i need a help how to solve this problem , also how can i measure how much current consumption of myrio while iam connecting all of these sensors 
any idea?

You may need to externally power your sensors using a different power supply.

This can happen if your code has very fast loops. Those will consume all CPU time and not give enough time for communication with host PC.

I don't think it is a power problem. If it were, power will go down directly after you connect sensors, not run your code. Try to increase loop time using delays. Increase time-loop period if you are using timed loops.

 

Are you programming using USB or wifi? Does any of your sensors use wifi?

thank you for replaying
yes you are right the problem is in the code it self I have like 4 loops separate and my pc has only 2 processor
"Are you programming using USB or wifi? Does any of your sensors use wifi?"
