-------------### Example 1: Sending Sensor Data to Azure IoT Hub using CThis example demonstrates how to collect sensor data from the onboard sensors and send it to Azure IoT Hub using the Azure IoT Device SDK for C.```c
#include <az_iot_hub.h>
#include <az_iot_hub_client.h>
#include <sensor.h>// Initialize the Azure IoT Hub client
az_iot_hub_client client;
az_iot_hub_client_init(&client, "your_iothub_name", "your_device_id", "your_device_key");// Initialize the temperature and humidity sensor
sensor temp_humidity_sensor;
sensor_init(&temp_humidity_sensor, SENSOR_TYPE_TEMP_HUMIDITY);while (1) {
// Read temperature and humidity data from the sensor
float temperature, humidity;
sensor_read(&temp_humidity_sensor, &temperature, &humidity);// Create a telemetry message to send to Azure IoT Hub
az_iot_hub_telemetry telemetry;
telemetry.properties_count = 2;
telemetry.properties[0].key = "temperature";
telemetry.properties[0].value = temperature;
telemetry.properties[1].key = "humidity";
telemetry.properties[1].value = humidity;// Send the telemetry message to Azure IoT Hub
az_iot_hub_client_send_telemetry(&client, &telemetry);// Wait for 1 minute before sending the next message
delay(60000);
}
```### Example 2: Controlling LEDs using Azure IoT Hub and Azure FunctionsThis example demonstrates how to use Azure IoT Hub and Azure Functions to control the onboard LEDs remotely.```c
#include <az_iot_hub.h>
#include <az_iot_hub_client.h>// Initialize the Azure IoT Hub client
az_iot_hub_client client;
az_iot_hub_client_init(&client, "your_iothub_name", "your_device_id", "your_device_key");// Initialize the LEDs
gpio_init(LED1, GPIO_MODE_OUTPUT);
gpio_init(LED2, GPIO_MODE_OUTPUT);while (1) {
// Receive messages from Azure IoT Hub
az_iot_hub_client_receive(&client);// Check if a message is available
if (az_iot_hub_client_message_available(&client)) {
char message = az_iot_hub_client_get_message(&client);
if (strstr(message, "-turn_on_led1")) {
gpio_write(LED1, 1);
} else if (strstr(message, "turn_off_led1")) {
gpio_write(LED1, 0);
} else if (strstr(message, "turn_on_led2")) {
gpio_write(LED2, 1);
} else if (strstr(message, "turn_off_led2")) {
gpio_write(LED2, 0);
}
free(message);
}
}
```### Example 3: Displaying Sensor Data on the OLED Display using CThis example demonstrates how to read sensor data and display it on the onboard OLED display.```c
#include <oled.h>
#include <sensor.h>// Initialize the OLED display
oled_init();// Initialize the temperature and humidity sensor
sensor temp_humidity_sensor;
sensor_init(&temp_humidity_sensor, SENSOR_TYPE_TEMP_HUMIDITY);while (1) {
// Read temperature and humidity data from the sensor
float temperature, humidity;
sensor_read(&temp_humidity_sensor, &temperature, &humidity);// Clear the OLED display
oled_clear();// Display temperature and humidity data on the OLED display
char buffer[20];
sprintf(buffer, "Temperature: %.2f C", temperature);
oled_display_string(0, 0, buffer);
sprintf(buffer, "Humidity: %.2f %%", humidity);
oled_display_string(1, 0, buffer);// Wait for 1 second before updating the display again
delay(1000);
}
```These examples demonstrate the capabilities of the MXChip Microsoft Azure IoT Developer Kit and provide a starting point for building a wide range of IoT projects.
