Package installation to Saleae’s Python is not so easy but not impossible. This post covers it briefly.
In this post I stream the data from HLA to my own pipe listener, and from the pipe listener to a virtual com port. You can do further math operations (arithmetic or logic) on the pipe listener just before sending your data to the com port. After redirecting the data to the com port, you can use apps like SerialPlot or any other software to visualize your data. Or you can also visualize your data right in the pipe listener C# app without even sending the data to any com port, it’s up to you.
I wish this feature were already implemented in the original software but not and I don’t see it coming in a near future
