PDL Diagnostic Print

This project provides a diagnostic printing module using FreeRTOS for task and queue management, designed for serial communication. It includes functionalities for initialization, deinitialization, and printing of diagnostic messages.

Features

Initialization and Deinitialization:
- Default and custom initialization (init) and deinitialization (deinit) functions.
Printing:
- Default and custom print functions.
Thread Safety:
- Uses mutex and queue for thread-safe printing.
Task Management:
- A FreeRTOS task for handling queued messages.

Usage

Initialization

To initialize the diagnostic print module:

if (!diagnostic_print_init()) {
    // Handle initialization error
}

Setting Custom Functions

You can set custom initialization, deinitialization, and print functions:

diagnostic_print_set_init_func(custom_init_func);
diagnostic_print_set_deinit_func(custom_deinit_func);
diagnostic_print_set_print_func(custom_print_func);

Printing Messages

To print a formatted message:

diagnostic_printf("Formatted message: %d", value);

To print a message with a newline:

diagnostic_println("Message with newline");

Deinitialization

To deinitialize the diagnostic print module:

diagnostic_print_deinit();

Unit Testing

Unit tests are provided in the unit_test.ino file. These tests demonstrate the usage of the diagnostic print module and verify its functionality.

Running the Unit Tests

Open the unit_test.ino file in the Arduino IDE.
Upload the code to your Arduino board.
Open the Serial Monitor to view the test results.
