Signal Generator

Small usefull ESP32 signal generator.

Fusion360 file included.
ESP32 code included as .txt file, just rename it to .ino and upload via Arduino IDE.

It uses ESP32 DAC pin(25) you can use 26 or both as well.
ESP32 - 25(DAC1) or 26(DAC2) PIN

Encoder pinout:
encoderPinA = 13,
encoderPinB = 27,
encoderButton = 15 // button PIN

OLED is using I2C
SDA(GPIO21)
SCL (GPIO22)

I have used Single Row Pin Female Header Socket Pitch 2.54mm connector for output, for GND, +3.3V, +5V and two DAC channel outputs.
