arduino as source of signal and A/D convertor

[topalovic.luka]

Hi everyone,

I want to make an oscilloscope with arduino, but I want to use tone generator as source of signal condition it with some circuites and then get it back to analog input to read it. Can I do it in same loop? Is that even possible?

I don't see why you can't do what you want.  Simply set the tone output and then start reading the analog pin.  Is there something else in your project that prevents you from doing that?

Thank you for reply, Nathan! I doesnt work, I tried it. I put int ardunio function, then continuous aqcusition on function, tone function and continuous acqusition sample function after tone. After continuous aqcusition on function when I turn on highlight execution, shows error.I tried at first with simple pwm module to detect it, but it shows voltage around 5V and then stops working. Here is my block diagram.
