Module esp32_hal::system

System Control

Overview

This system driver provides an interface to control and configure various system-related features and peripherals on ESP chips. It includes functionality to control peripheral clocks, manage software interrupts, configure chip clocks, and control radio peripherals.

Software Interrupts

The SoftwareInterrupt enum represents the available software interrupt sources.

The SoftwareInterruptControl struct allows raising or resetting software interrupts using the raise() and reset() methods. The behavior of these methods depends on the specific chip variant.

Peripheral Clock Control

The PeripheralClockControl struct controls the enablement of peripheral clocks.

It provides an enable() method to enable and reset specific peripherals. The available peripherals are represented by the Peripheral enum

Example

let peripherals = Peripherals::take();
let system = peripherals.SYSTEM.split();
let clocks = ClockControl::boot_defaults(system.clock_control).freeze();
