Module esp32_hal::clock_control[][src]

Expand description

Clock and RTC watchdog control.

Controls the clock source for CPU, RTC, APB, etc. Also controls RTC watchdog timer.

TODO

  • Auto detect flash frequency
  • Low Power Clock (LPClock, regs: DPORT_BT_LPCK_DIV_FRAC_REG,DPORT_BT_LPCK_DIV_INT_REG)
  • LED clock selection in ledc peripheral
  • 8M and 8MD256 enable/disable
  • 150kHz enable/disable
  • APLL support
  • Implement light sleep
  • 32kHz Xtal support
  • Allow 8.5MHz clock to be tuned
  • Automatic enabling/disabling of 8MHz source (when not in use for rtc_fast_clk or cpu frequency)

Modules

Control Cores

Dynamic Frequency Switching control

RTC Watchdog implementation

Structs

Clock Control for initialization. Once initialization is done, call the freeze function to lock the clock configuration. This will return a ClockControlConfig, which can be copied for e.g. use in multiple peripherals.

Clock configuration & locking for Dynamic Frequency Switching. It allows thread and interrupt safe way to switch between default, high CPU and APB frequency configuration.

Enums

CPU/APB/REF clock source

RTC Clock errors

Fast RTC clock source

Slow RTC clock source
