Hello everybody!

Here is my problem: I have a frame of data from ADC (atmega 32) in 16 - bit array: 165|90|2|counter|byteADC 1| byteADC 2| byteADC 3| byteADC 4. How can I extract data (byteADC 1 etc.) from this frame? 'I' is a separator. I tried to save this frame to array of strings but with no further result. Have you any idea how to do this? On the end I want to present data in real time on chart.

I would use the Spreadsheet String to Array function with "|" as the delimiter.  Then it is a simple matter of just indexing out the data you want.

The Spreadsheet String to Array works and all you have to do is index the array. Post an image of your block diagram if you still have problems after doing this.

Okay, I'd like to extract a counter from my data frame and view number of count in each iteration. But it doesn't work.

Wire in a 1D array to the type input of the Spreadsheet String to Array function.  Then you will just have a scaler coming out after you index the element you need.

You're going to have to be a bit more precise. A simple statement of 'it doesn't work' is pretty meaningless.

Yeah, sorry for that. Ok, I'm going to improve my program, but how can i limit incoming data to array? 165|90|2 it's a starting index, and in that way i recognise where frame starts. Should I try something like cyclic buffer or prepare 'for' statement? Which solution is better? Thanks for your past answers.

You are already limiting the data. The read is set to automatically terminate with s termination character so the byte count just had to be set for some arbitrarily high number.

It's AMAZING how simply it is! 🙂 It really works, thank you a lot!
