imxrt-hal 0.5.14

//! Demonstrates imxrt-log text and defmt logging.
//!
//! Modify the `FRONTEND` and `BACKEND` configurations to combine log / defmt
//! with a LPUART or USB CDC logger. When LPUART is selected, the log messages
//! are written over the board's console; see your board's `Console` documentation
//! for information on the settings. When a USB device is selected, the log messages
//! are written over a USB serial interface.
//!
//! See the `imxrt-log` documentation for more information on each logging backend.
//!
//! This example does not use interrupts. For an example that demonstrates interrupt-driven
//! loggers, see the rtic_logging example.

#![no_std]
#![no_main]

//
// Configure the demo below.
//

/// Change me to change how log messages are serialized
/// and transported.
const FRONTEND: board::logging::Frontend = board::logging::Frontend::Log;
/// This is a function of your board. Want to change it? Change it right
/// here to explore different example code paths.
const BACKEND: board::logging::Backend = board::logging::BACKEND;

/// How frequently (milliseconds) should we make a log message?
///
/// Decrease this constant to log more frequently.
const MAKE_LOG_INTERVAL_MS: u32 = board::PIT_FREQUENCY / 1_000 * 250;

//
// End configurations.
