AC converter to DC

[gpfacu]

Hi,

I´m trying to generate an AC signal with my ESP-32 and I´m having some inconviniences. I´m going to be sending squared pulses from 0V to 3.3V, the period is going to depend on what I need at the moment, but generally it´ll be something like 10ms ON - 100ms OFF. Can anyone give me some advice on how to achieve this?

Thanks!

The ESp32 has a DAC, you should look into using that.

Use a timer. Set it to e.g. 100ms. When it expires, turn output on, reset timer to 10ms; next time it expires, turn output off, reset timer to 100ms.
