Make an oscilloscope using stm 32

[TalhaZahid]

Hi, everyone I am Talha an Electronics student, I was recently working on making an oscilloscope using STM 32. I recently made a logic analyzer using stm 32 f103 RB. I now wanted to make a simple oscilloscope that simply displays the function generator's data. 
What I want is that I want to give an input signal using a simple function generator and display it on a serial analyzer. Now I don't get the problem as I tried to simply read the data and send it to USART and display it on the serial analyzer but unfortunately, there was a lot of noise, I don't get it what should I do, I have 2 STM 32 one with an ADC in it.

It is a request to please help me If you can. I also need to integrate the output with a GUI I've designed using Flutter, but I would take care of it on my own.

Help needed anyone with a similar experience please help.

Hi,

there are many "mini DSO" on git, just look how they do it :

Is your project for the Logic analyzer open source? I want to learn how to design these types of systems.

I already had a look at this project but I couldn't understand it as it has a lot of missing files like main.h. Any other solution?

This is just the analyzer on which I can observe the wave, I want the code or the logic part of this project
