If I pass 19, which is an ADC pin, intoanalogInputToDigitalPin(p)it would return 20. This is unlikedigitalPinToInterrupt, which returns the same pin number. There is also no check that the value is greater or equal to 0 These functions assume that all pins with the same type of functi...

ESP32’s digital pins are divided into three different power domains: • VDD3P3_RTC • VDD3P3_CPU • VDD_SDIO VDD3P3_RTC is also the input power supply for RTC and CPU. VDD3P3_CPU is also the input power supply for CPU. VDD_SDIO connects to the output of an internal LDO wh...

Unlike the Arduino UNO where analog pins are limited to 6, the ESP32 has 18 channels. You can view all the analog pins in the ESP32 pinout diagram above. Digital to Analog Converter Pins Digital to Analog Converter (DAC) pins enable the generation of analog output signals. This feature is...
Re: Digital pins usable for interrupts Postbybobtidey»Sun Oct 07, 2018 9:56 pm I believe that any GPIO that can be used for normal input can be used as an interrupt source. All GPIO events get handled by a common single low level interrupt handler. In the esp32 Arduino the attachIn...
input pins only. They cannot be configured as digital output pins. Also, unlike other GPIO pins, these pins do not have internally connected push-pull resistors. Therefore, when using any one of these pins as a digital input pin, we need to connect an external pull-up or pull-down ...
