I've got an black pill with STM32F411CEU6 on it, I plan to simply use it for a single purpose: reading ADC at near full capacity and transfer values to PC via USB. After investigating around F411 product page on st.com, I've found that:ADCin product ...

hi guys, I'm a desktop programmer and do not know much about micro controllers and electronics but i am very interested in making an oscilloscope which:- simple to build with well known parts and ICs- it uses bluepill as the ADC and no other ADCs- i...

using SPI instead of USB1 could be a solution too.anyways i think USB 2 (High Speed HS with 480Mbps bandwidth) would be more than enough for this case. (3*2.4Msps*12bit = 90Mbps)

I am not thinking that this website is kind of Q/A website, but I did expect an opinion based solution also wanted to find some collaboration. I'll break problem into smaller separated questions (if they are not already asked). Thank you guys for the...

Or is there any method i can have two channels ADC reading with 800Ksps and they sent to PC via USB?

Thanks for the link.I have already seen it. but not sure how do they handle reading of negative voltage for example. do you know anyone which does it?

my first question is how to measure negative voltage without letting user to do any options?I was thinking to use voltage adder to add a fixed voltage to my signal, and then simply sample on both channels (signal and fixed voltage) and negate values ...
