Hardware Overview
How does it work?
Flicker Click is based on the G6D-ASI, a power PCB relay from OMRON. It has a long service life with up to 300.000 operations at maximum rated loads. Its contact resistance is 100mΩ, with 5ms of release time, and it is designed to withstand 500VDC. Its coil is powered by 5V from the mikroBUS™ socket. The load can be connected to the relay over the onboard screw terminal and isolated from the board. Remember not to touch the board while the external power supply is on; the Flicker Click has exposed pins/pads. Thanks to
the onboard NE556, a dual precision timer from Texas Instruments, and two onboard 500K potentiometers, you can easily set the on/off periods. You will need a fine screwdriver to set the desired position of the potentiometers. A stopwatch can measure the ON/OFF periods if you need precise time. This way, you can set different or the same periods for both on and off states. The onboard LED stands for the visual presentation of the status of the relay. The Flicker Click uses a FON pin of the mikroBUS™ socket to communicate
with the host MCU. Over this pin, you can turn the NE556 ON and OFF. This Click board™ can be operated only with a 5V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.
Features overview
Development board
Fusion for TIVA v8 is a development board specially designed for the needs of rapid development of embedded applications. It supports a wide range of microcontrollers, such as different 32-bit ARM® Cortex®-M based MCUs from Texas Instruments, regardless of their number of pins, and a broad set of unique functions, such as the first-ever embedded debugger/programmer over a WiFi network. The development board is well organized and designed so that the end-user has all the necessary elements, such as switches, buttons, indicators, connectors, and others, in one place. Thanks to innovative manufacturing technology, Fusion for TIVA v8 provides a fluid and immersive working experience, allowing access
anywhere and under any circumstances at any time. Each part of the Fusion for TIVA v8 development board contains the components necessary for the most efficient operation of the same board. An advanced integrated CODEGRIP programmer/debugger module offers many valuable programming/debugging options, including support for JTAG, SWD, and SWO Trace (Single Wire Output)), and seamless integration with the Mikroe software environment. Besides, it also includes a clean and regulated power supply module for the development board. It can use a wide range of external power sources, including a battery, an external 12V power supply, and a power source via the USB Type-C (USB-C) connector.
Communication options such as USB-UART, USB HOST/DEVICE, CAN (on the MCU card, if supported), and Ethernet is also included. In addition, it also has the well-established mikroBUS™ standard, a standardized socket for the MCU card (SiBRAIN standard), and two display options for the TFT board line of products and character-based LCD. Fusion for TIVA v8 is an integral part of the Mikroe ecosystem for rapid development. Natively supported by Mikroe software tools, it covers many aspects of prototyping and development thanks to a considerable number of different Click boards™ (over a thousand boards), the number of which is growing every day.

Application Output via UART Mode
1. Once the code example is loaded, pressing the "FLASH" button initiates the build process, and programs it on the created setup.
2. After the programming is completed, click on the Tools icon in the upper-right panel, and select the UART Terminal.
3. After opening the UART Terminal tab, first check the baud rate setting in the Options menu (default is 115200). If this parameter is correct, activate the terminal by clicking the "CONNECT" button.
4. Now terminal status changes from Disconnected to Connected in green, and the data is displayed in the Received data field.

* # Description
* This application simple solution if you need to turn a device on and off at specific time intervals.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initialization driver enables GPIO and also starts write log.
*
* ## Application Task
* This example demonstrates capabilities of Flicker Click board.
