Good morning,
While working on a test bench, I encountered the following problem.
I have five laboratory power supplies connected to the computer, connected via the USB port, seen as COM ports. Each power supply is controlled and queried for parameters in a separate loop. During the operation of all power supplies, the read data is distorted. The read data is sometimes a fragment of data from another COM port or a string of random characters. When connecting two power supplies, I did not notice such a problem. Switching the read and write functions to synchronous mode of work improved a little, but from time to time the same problem occurs.
Has anyone encountered such a problem before? If so, please help me solve the problem.
And sorry for my language.
