[−][src]Crate ruspiro_mailbox
Mailbox property tag interface
This crate provides an abstraction on the mailbox property tag interface available in the Raspberry Pi. There are currently a limmited number of functions for the following property tag messages implemented:
- GetArmMemory
- GetClockRate
- SetClockRate
Check the official documentation of those property tags and their purpose.
Usage
The crate provides a singleton wrapper to call the different Raspberry Pi mailbox property tag messages. The following example demonstrates the usage with the GetClockRate message.
use ruspiro_mailbox::*; fn demo() { // use the mailbox to retrieve the core clock rate if let Ok(core_rate) = MAILBOX.take_for(|mb| mb.get_clockrate(ArmClockId::Core)) { // here we know the core clock rate do something with it... println!("Core clock rate {}", core_rate); } }
Features
ruspiro_pi3
is active by default and ensures the proper MMIO base address is compiled for Raspberry Pi 3
