Lab 1: Create the Application

 Objective

In Lab 1, you will create an MPLAB Harmony v3 project using Microchip Harmony Configurator (MHC). The application you create will utilize:

  • A button to switch the application on or off
  • Timer System Service using TC Peripheral Library to periodically sample temperature sensor data
  • Asynchronous I2C driver using I2C Peripheral Library to read temperature from a temperature sensor
  • Debug System Service and Console System Service using CDC USB Peripheral Library to print the temperature values on a COM (serial) port terminal application running on a PC.

Overview

The whole application is divided into four tasks.

  • Sensor task
  • SD Card task
  • USB task
  • Wi-Fi task

Each task runs its own state machine. The tasks are called from the SYS_Tasks() routine, which is run in an infinite loop.

In Lab 1, you will develop the Sensor task which includes the USB operations to print the sensor logs.
