Crate avr_config[−][src]
Foundational crate for retrieving details about the target AVR being compiled for.
This crate currently exposes the CPU frequency that is being configured for.
The AVR_CPU_FREQUENCY_HZ environment variable
All crates that depend on this crate (with the cpu-frequency feature enabled) require $AVR_CPU_FREQUENCY_HZ when targeting
AVR. The frequency will then be available in the CPU_FREQUENCY_HZ constant.
It is not necessary to set this variable when AVR is not being targeted, for example, when running integration tests on the host machine.
