Read from multiple ports simultaneously

Question

0 个投票

Hi,

I'm trying to read data from three devices simultaneously (2 devices works at 100 Hz and the 3rd at 2000 Hz) and plot the data in real-time using one timer. I'm using 'BytesAvailableFcn' for each port.

When I'm working with each of them separately my code works fine and display the graph perfect but when I'm trying to read from 2 or 3 together I receive odd data and get delays in my plotting.

I think the problem is that the ports interrupt each other. Does anyone have a solution for this problem? by the way I'm not using multi-thread, should I use parallel processing?

Thanks, Nir

How are the devices interfaced? Are they all implemented as Serial Over USB (virtual serial, serial emulation), with all of them being connected to the same USB controller ?
