Module atsamd_hal::clock

source · [−]
Expand description

Configuring the system clock sources. You will typically need to create an instance of GenericClockController before you can set up most of the peripherals on the atsamd21 device. The other types in this module are used to enforce at compile time that the peripherals have been correctly configured.
