How to write software to work with devices?

Question

Visual Basic

We have an old program written in Visual Basic. This program works with blood reading devices (blood analysis) - the devices themselves are old. Now the task arose to slightly update the program itself, namely, to connect 1 new device to it and at the same time upload the analysis data to the cloud immediately. The project is here https://www.dropbox.com/sh/6deakxu0kc5ks65/AADRkB8...
We are a little confused about what kind of developer we need for analytics? and others need a completely different C/C++. Please tell me what specialty you need to connect a person to figure it out.

Answer 1

I would recommend looking towards Python - since it is easier to refine it, there may be a cross-platform (windows, linux) implementation, which in the wake of "import substitution" will be very acceptable. Plus there are a lot of libraries for Python...
C# is .Net; and .Net is MS Windows; and MS Windows is a foreign software from which our state intends to refuse. So it is logical to look towards Linux + Windows cross-platform solutions. Write a beautiful user-friendly Qt interface and modules to work with each type of device.
Most of the devices you have are RS232 - in python you can work with them without problems, it will not take much time for an experienced programmer.
You will have to form a clear TOR for the Graphic Program - so that it will be convenient to work with it later. First of all, programmers should be consulted by a measurement specialist, because programmers will have a hard time understanding what is wanted from them.
