Struct SpiEventSource 

pub struct SpiEventSource<'d> { /* private fields */ }

Source/mechanism to use for getting notifications/events from the emac.

Availability

Pre version v5.1.4 of esp-idf, only an interrupt pin could be used as source:

• v4.4: https://github.com/espressif/esp-idf/blob/e499576efdb086551abe309a72899302f82077b7/components/esp_eth/include/esp_eth_mac.h#L461-L464
• v5.0: https://github.com/espressif/esp-idf/blob/bcca689866db3dfda47f77670bf8df2a7ec94721/components/esp_eth/include/esp_eth_mac.h#L513-L517
• v5.1.3: https://github.com/espressif/esp-idf/blob/e7771c75bd1dbbfb7b3c5381be7e063b197c9734/components/esp_eth/include/esp_eth_mac.h#L612-L617
• V5.2.0: https://github.com/espressif/esp-idf/blob/11eaf41b37267ad7709c0899c284e3683d2f0b5e/components/esp_eth/include/esp_eth_mac.h#L612-L617

Starting with v5.1.4, v5.2.1 and >= v5.3 the option of poll_period_ms became available:

• v5.1.4: https://github.com/espressif/esp-idf/blob/d7b0a45ddbddbac53afb4fc28168f9f9259dbb79/components/esp_eth/include/esp_eth_mac.h#L614-L620
• v5.2.1: https://github.com/espressif/esp-idf/blob/a322e6bdad4b6675d4597fb2722eea2851ba88cb/components/esp_eth/include/esp_eth_mac.h#L614-L620
• v5.3-dev: https://github.com/espressif/esp-idf/blob/ea010f84ef878dda07146244e166930738c1c103/components/esp_eth/include/esp_eth_mac.h#L694-L700

Implementations

impl<'d> SpiEventSource<'d>

pub fn polling(interval: Duration) -> Result<Self, TryFromIntError>

Instead of getting informed by an interrupt pin about updates/changes from the emac, the MCU polls the emac periodically for updates.

In most cases, Self::interrupt should be used as it is more efficient. But this source makes e.g. sense if the interrupt pin of the emac is not connected to the MCU.

pub fn interrupt(pin: impl InputPin + 'd) -> Self

Get status updates/changes from the emac by way of an interrupt pin.

If the interrupt pin is not connected, see Self::polling for an alternative.
