A usable and minimal USB osciloscope with bluepill

[epsi1on]

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

- it be able to measure negative voltages

- It uses near maximum  ADC sample rate possible from bluepill

 Single channel would be enough for above spects. recently I was working with a cool project named rp2daq which convert RPI Pico to a 500KSps /12Bit resolution and uses USB to send data to PC.

I did try to make a proof of concept version of a oscilloscope on top of it and it did worked (kind of) available from here.

I was using this simple oscilloscope since last day which i gave 10v signal to it's ADC by mistake and it broke.

The pico is expensive relate to blue pill (in my area, 3x more expensive), so i am thinking if anyone interest in making such open source scope, i think I can fully do the desktop part and need help for the micro controller side.

Or at least you could give me some guidelines for that.

Thanks
