STM32F767ZI: Environmental Station Demo

[alieissa-commits]

Description

Develop a telemetry acquisition and remote monitoring pipeline. This involves configuring an I2C sensor interface, reading data on a periodic scheduler, and publishing JSON telemetry to an online MQTT broker over Ethernet.

• Configure I2C Peripheral: Initialize the I2C1 controller in board_init.c mapping to the board's Arduino Uno V3 shield headers (pins CN9/CN10).
• Write Sensor Driver: Write code to poll a physical I2C sensor. Implement a robust Software Simulator Fallback that generates realistic telemetry if no physical sensor is attached.
• Implement sensor_thread: Poll the sensor every 5 seconds, package the data and send the data structure over a ThreadX Message Queue.
• Integrate NetX Duo DNS & MQTT: Add the NetX Duo DNS and MQTT client source files to the CMake build.
• Implement network_thread:
  • Use the DNS client to resolve a public MQTT broker.
  • Establish a secure/unsecure TCP connection to the broker.
  • Consume telemetry records from the Message Queue, serialize them into JSON strings, and publish them to a topic.
