Introduction

This unit test carries out tests for the EVENTS driver.

It consists of test cases for the following functionalities:

• Test for synchronous event propagation.
• Test for resynchronized event propagation.
• Test for asynchronous event propagation.

This unit test carries out test for three modes of event propagation: Synchronous, Resynchronized & Asynchronous.

• A RTC module with internal 32kHz RC oscillator is configured as an event generator and a Timer Counter (TC3) module is configured as event user.
• RTC overflow signal is sent as an event to the timer. The timer will start counting on receiving this event.
• The timer's count register is read to detect successful event action.

The following kits are supported for carrying out the test:

• SAM D20 Xplained Pro board
• SAM D21 Xplained Pro board
• SAM R21 Xplained Pro board
• SAM L21 Xplained Pro board
• SAM L22 Xplained Pro board
• SAM DA1 Xplained Pro board
• SAM C21 Xplained Pro board
• SAM HA1G16A Xplained Pro board
• SAM R30 Xplained Pro board
• SAM R30 Module Xplained Pro board
• SAM R34 Xplained Pro board
• WLR 089 Xplained Pro board

Setup

The following connections has to be made using wires:

• None

To run the test:

• Connect the Xplained Pro board to the computer using a micro USB cable.
• Open the virtual COM port in a terminal application.

  Note

  The USB composite firmware running on the Embedded Debugger (EDBG) will enumerate as debugger, virtual COM port and EDBG data gateway.

• Build the project, program the target and run the application. The terminal shows the results of the unit test.

Usage

• The unit test carries out test for three modes of event propagation: Synchronous, Resynchronized & Asynchronous.
• RTC module with internal 32kHz RC oscillator is configured as event generator and Timer (TC3) module is configured as event user.
• RTC overflow signal is sent as an event to the timer. The timer will start counting on receiving this event.
• Timer's count register is read to detect successful event action.

Compilation Info

This software was written for the GNU GCC and IAR for ARM. Other compilers may or may not work.
