[−][src]Module esp32_hal::gpio
GPIO and pin configuration
ESP32 has very flexible pin assignment via the GPIO mux. It also has a separate RTC mux for low power and analog functions.
To support this flexibility two sets of traits are supported:
- The various embedded_hal properties
- Dedicated InputPin, OutputPin, RTCInputPin and RTCOutputPin
The advantage of using the dedicated traits in peripherals is that the configuration of the IO can be done inside the peripheral instead of having to be done upfront.
