I tried this code and it worked in arduino IDE for ESP32. Note: I used it to generate 200kHz and had steps in the output wave. Do change as per your need. // Function generator Sin // (C) Helmut Weber // // Provided as is as example // Free for everyone // // 50 Hz - 200000Hz: frequency error ~ 1% ...

I am new to esp32 and am using Arduino IDE. Can anyone suggest how this code can be written in Arduino IDE?
