Crate esp32c2_hal

Re-exports

• pub use embedded_hal as ehal;

Modules

• adc
  Analog to digital (ADC) conversion support.
• analog
  Common module for analog functions
• assist_debug
  Debug Assistant
• clock
  Clock Control
• delay
  Delay driver
• dma
  Direct Memory Access Commons
• esp_riscv_rt
  Minimal startup / runtime for RISC-V CPUs from Espressif
• gpio
  General Purpose I/Os
• i2c
  I2C Driver
• interrupt
• ledc
  LEDC (LED PWM Controller) peripheral control
• macros
• peripheral
• prelude
  The prelude
• radio
• reset
• rng
  Random number generator driver
• rom
• rtc_cntl
• sha
• soc
• spi
  Serial Peripheral Interface
• system
  System
• systimer
• timer
  General-purpose timers
• trapframe
  State of the CPU saved when entering exception or interrupt
• uart
  UART driver

Macros

• create_peripheral
• into_ref
• peripherals
• regi2c_write
• regi2c_write_mask

Structs

• Delay
  Uses the SYSTIMER peripheral for counting clock cycles, as unfortunately the ESP32-C3 does NOT implement the mcycle CSR, which is how we would normally do this.
• IO
• Rng
  Random Number Generator
• Rtc
• Rwdt
  RTC Watchdog Timer
• Spi
• Timer
  General-purpose timer
• TrapFrame
  Registers saved in trap handler
• Uart
  UART driver

Enums

• Cpu
  Enumeration of CPU cores The actual number of available cores depends on the target.
• CpuInterrupt
  Enumeration of available CPU interrupts. It is possible to create a handler for each of the interrupts. (e.g. interrupt3)
• Error
  Interrupt Error
• InterruptKind
  Interrupt kind
• Priority
  Interrupt priority levels.

Functions

• clear
  Clear a CPU interrupt
• disable
  Disable the given peripheral interrupt.
• enable
  Enables a interrupt at a given priority
• enable_cpu_interrupt^⚠
  Enable a CPU interrupt
• get_core
• get_status
  Get status of peripheral interrupts
• map^⚠
  Assign a peripheral interrupt to an CPU interrupt.
• set_kind
  Set the interrupt kind (i.e. level or edge) of an CPU interrupt
• set_priority^⚠
  Set the priority level of an CPU interrupt

Attribute Macros

• entry
  Attribute to declare the entry point of the program
