Generate a Simple Audio Tone
Posted: Sun Sep 22, 2019 1:34 pm
Hi, I'm having a really hard time finding any information about something that sounds pretty simple: I want to generate a tone at a given frequency using the esp-idf libraries. I did find one example using audio https://github.com/espressif/esp-idf/tr ... 2s_adc_dac but I have no need for playing WAV samples and so the code is way more complicated than what I need. I just want to emit a tone at a frequency, without using any Arduino libraries. Can we do this?
