//! # Peripheral Instances
|
|
//!
|
|
//! This module creates singleton instances for each of the various peripherals,
|
|
//! and re-exports them to allow users to access and use them in their
|
|
//! applications.
|
|
//!
|
|
//! Should be noted that that the module also re-exports the [Interrupt] enum
|
|
//! from the PAC, allowing users to handle interrupts associated with these
|
|
//! peripherals.
|
|
|
|
use esp32c2 as pac;

// We need to export this for users to use

// Note that certain are marked with `virtual` in the invocation of the
|
|
// `peripherals!` macro below. Basically, this indicates there's no physical
|
|
// peripheral (no `PSRAM`, `RADIO`, etc. peripheral in the PACs), so we're
|
|
// creating "virtual peripherals" for them.
