Tomáš Pilný 3e85c1886e esp32/dac-one-shot: lower-half driver for ESP32 internal DAC
Enable with ./tools/configure.sh -l esp32-devkitc:dac
DAC channel 0 = GPIO 25
DAC channel 1 = GPIO 26
default path: /dev/dac0

Resolution 8 bits = values 0~255
Voltage: 0~Vref

The reference voltage 'Vref' here is input from the pin VDD3P3_RTC
which ideally equals to the power supply VDD (3.3V).
