Struct EspControlPins

pub struct EspControlPins<CS, GPIO0, RESETN, ACK> {
    pub cs: CS,
    pub gpio0: GPIO0,
    pub resetn: RESETN,
    pub ack: ACK,
}

A structured representation of all GPIO pins that control a ESP32-WROOM NINA firmware-based device outside of commands sent over the SPI/I²C bus. Pass a single instance of this struct into Wifi::init().

Fields

cs: CS

Chip select pin to let the NINA firmware know we’re going to send it a command over the SPI bus.

gpio0: GPIO0

Puts the ESP32 WiFi target into bootloading mode. Or if acting as a server, provides a status line for when data is ready to be read.

resetn: RESETN

Places the ESP32 WiFi target into reset mode. Useful for when the target gets into a stuck state.

ack: ACK

Is the ESP32 WiFi target busy?

Trait Implementations

impl Default for EspControlPins<(), (), (), ()>

fn default() -> Self

Returns the “default value” for a type.

impl<CS, GPIO0, RESETN, ACK> EspControlInterface for EspControlPins<CS, GPIO0, RESETN, ACK>

where CS: OutputPin, GPIO0: OutputPin, RESETN: OutputPin, ACK: InputPin,

fn init(&mut self)

Initializes all controls pins to set ready communication with the NINA firmware.

fn reset<D: DelayMs<u16>>(&mut self, delay: &mut D)

Resets communication with the NINA firmware.

fn esp_select(&mut self)

Tells the NINA firmware we’re about to send it a protocol command.

fn esp_deselect(&mut self)

Tells the NINA firmware we’re done sending it a protocol command.

fn get_esp_ready(&self) -> bool

Is the NINA firmware ready to send it a protocol command?

fn get_esp_ack(&self) -> bool

Is the NINA firmware ready to receive more commands? Also referred to as BUSY.

fn wait_for_esp_ready(&self)

Blocking waits for the NINA firmware to be ready to send it a protocol command.

fn wait_for_esp_ack(&self)

Blocking waits for the NINA firmware to acknowledge it’s ready to receive more commands.

fn wait_for_esp_select(&mut self)

Blocking waits for the NINA firmware to be ready to send it a protocol command.
