Module stm32wlxx_hal::rcc

Reset and clocking control

Unlike other HALs clocks do not get frozen. A lot of applications for this chip will require low-power, and there are many scenarios where you will want to adjust the clocks.

Quickstart: set_sysclk_msi_max

Structs

• Lsco
  Low-speed oscillator output pin.

Enums

• LscoSel

• LsiPre
  LSI frequency prescaler
• MsiRange
  MSI clock ranges.
• Vos
  Voltage scaling
