Module kernel::debug[][src]

Support for in-kernel debugging.

For printing, this module uses an internal buffer to write the strings into. If you are writing and the buffer fills up, you can make the size of output_buffer larger.

Before debug interfaces can be used, the board file must assign them hardware:

kernel::debug::assign_gpios(
    Some(&sam4l::gpio::PA[13]),
    Some(&sam4l::gpio::PA[15]),
    None,
    );

let kc = static_init!(
    capsules::console::App,
    capsules::console::App::default());
kernel::debug::assign_console_driver(Some(hail.console), kc);

Example

debug!("Yes the code gets here with value {}", i);
debug_verbose!("got here"); // includes message count, file, and line
debug_gpio!(0, toggle); // Toggles the first debug GPIO
Yes the code gets here with value 42
TOCK_DEBUG(0): /tock/capsules/src/sensys.rs:24: got here
