Good day .
I'm a beginner here.
Question - does anyone know the project - a frequency generator rectangular impulses
with an adjustment of 0.01 hertz, and an indicator for 16x2 I2C?
I used this project, now I need to change the display to 16x2 I2C and the adjustment is a multiple of 0.01 hertz
Thank you in advance for your answers! Respectfully!
I agree it sounds like a school assignment. But I’m no longer a schoolboy. Measurements will be carried out by an oscilloscope. but accuracy is not too important. the main thing is to be able to adjust with an indication of 0.01 hertz. there are 2 arduino, several LСD.
With respect!
Ok so you don’t mean accuracy you mean resolution. Even so :-
At 50KHz, that is 50000 HZ and the resolution you need is 0.01 HZ, so you need to control one part in 5,000,000, but you can double that because you have to set the output high and low for a cycle of output.
So for a processor running at 16MHz you need to be changing the output every 1.6 clock cycles. So can you see you can’t do this?
