MPLAB® Harmony v3 Drivers on SAM E70/S70/V70/V71 Using FreeRTOS™: Step 3

Step 3.1: Configure LED Pin

In this step, the User LED on the SAM E70 Xplained Ultra Evaluation Kit will be configured according to the USER_LED0 design schematic below.


Select the MPLAB® Code Configurator (MCC) Pin Settings tab, scroll down to Pin Number 73, Pin ID PA05, and then configure the PORT pin PA05 as an output pin for LED functionality.


The LED on the SAM E70 Xplained Pro board is active low. Configure the LED in default OFF state by configuring the Latch value to High.

Step 3.2: Rename Default File

Under the Project Graph tab, click on System, and give a name of your choice to the default template main file generated by MCC.


The name of the default main.c is changed to main_e70.c to indicate that the referred main.c is for the SAM E70/S70/V70/V71 getting started training module.

Step 3.3: Configure Application Threads


Go to the Project Graph and select Harmony Core Service.



The Configuration Options tab shows that for a Harmony Project, MCC automatically enables the generation of application files (app.c and app.h).
Change the Number of Applications to 3.



Expand Application 0 Configuration and change the Application Name to app_sensor_thread. This will create an RTOS thread _APP_SENSOR_THREAD_Tasks.
Expand RTOS Configuration to configure Stack Size, Task Priority and Task Delay. For this thread, use the default values.



Expand Application 1 Configuration and change the Application Name to app_eeprom_thread. This will create RTOS thread _APP_EEPROM_THREAD_Tasks.
Expand Application 2 Configuration and change the Application Name to app_user_input_thread. This will create RTOS thread _APP_USER_INPUT_THREAD_Tasks.
Accept the default RTOS Configuration for both the threads.
