FALCAO

Hello everyone  :),

I want your help. I have an issue and i want to take some informations before ? buy an arduino. I want to know how is the delay(latency ), if exists, in trasnfering data from arduino to pc. Which are the factors that determine the delay. I want to know because the accuracy is vey important for my issue.

Thank you all for your time

It depends on many factors, some of which may not be under your control.
The most obvious factor is bit rate, which is up to you to decide.

How can i define the bit rate, with code?
The other factors that are not under my control, they have to do with hardware like sensors or the same arduino ?
If yes, these factors are most important for me. If i can not do anything then i need to know how is exactly the latency from these factors!
Is it possible?

I think the big unknown is on the PC side: once the data has been received (by the serial or USB port , how long does it take to get into the application program which processes the data on the PC? Since there are many processes running on the PC at the same time, the operating system needs some time to pick up the data and wake up the application program. I think you need to run the time critical part of your application entirely on the Arduino, where you have full control over time.
