basic_azurertos

Description

This application provides a basic example of Microsoft Azure RTOS functionality.

The application creates two threads and a message queue. Thread 1 attempts to pass a message to thread 2 via the queue and then sleeps for TX_DELAY. Thread 2 blinks the LED when the sent message is successfully received.

Configuration

The application behavior can be adjusted by modifying conf/app_conf.h.

Key configurations are stated below:

Azure RTOS

• MEM_BYTE_POOL_SIZE,THREAD_STACK_SIZE,QUEUE_SIZE in bytes defines Azure RTOS memory pool, threads and queue sizes

#define MEM_BYTE_POOL_SIZE 9120

#define THREAD_STACK_SIZE 1024

#define QUEUE_SIZE 100

App activity

• GNSE_TINY_TRACER_ENABLE enables UART (115200/8-N-1) logging of application activity

#define GNSE_TINY_TRACER_ENABLE 1

• TX_DELAY in milliseconds defines the message passing rate from thread 1 to thread 2.

#define TX_DELAY                 (5000)

Observation

The device blinks the blue LED every TX_DELAY on each successful message passing between thread 1 and thread 2.
