Hardware Overview
How does it work?
Shuttle Click consists of a high-quality PCB that can be connected to the mikroBUS™ as any other click board. The central part of the Shuttle click is populated with the four ICD BOX headers. Each of these four headers is connected to the same type of header on the add-on board, also known as mikroBUS Shuttle, by a flat ribbon cable. Thanks to the ICD BOX headers, the connection remains firm and stable. Besides the ICD BOX headers, these mikroBUS Shuttle add-on boards also have one mikroBUS™ equipped so that the click board can be securely fitted to it. This stacking topology allows for easy manipulation and reconfiguration of the stacked click boards™, retaining a perfect connection quality at all times. When there's a need to expand the development system with even more mikroBUS™ slots, one of the free
mikroBUS shuttles can be populated with yet another Shuttle Click, allowing even more connections. This makes the stacking capacity almost unlimited. However, attention should be paid not to make mikroBUS™ lines too long. In situations like this, the frequency of the communication might need to be stepped down a bit to compensate for the longer mikroBUS™ signal lines. Lines of the mikroBUS™ to which Shuttle click is attached are shared through all four ICD BOX headers - each of the four ICD BOX 2x8 pin headers mirrors pins of the connected mikroBUS™. Therefore, each mikroBUS Shuttle add-on board shares the same mikroBUS™ pins as the other mikroBUS Shuttles connected to the same Shuttle click. For this reason, extra care should be taken when working with click boards™
that share the same pins on the mikroBUS™, either for communication (SPI, UART, I2C) or for some other purpose (RST, INT, or other pins used as GPIO). For example, I2C and 1-Wire protocols are designed with stacking in mind, so the collision avoidance mechanisms are already in place for these protocols. It is enough to change the slave address of the click board™, and data collision won't be a problem anymore, even while sharing the same pins for communication. Also, since all the stacked click boards™ share the same power rails, care should be taken when combining click boards™ with significant power consumption. The power consumption from all the click boards™ combined should not exceed the maximum power a development system can deliver.
Features overview
Development board
Fusion for STM32 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 STMicroelectronics, regardless of their number of pins, and a broad set of unique functions, such as the first-ever embedded debugger/programmer over WiFi. 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 STM32 v8 provides a fluid and immersive working experience, allowing
access anywhere and under any circumstances at any time. Each part of the Fusion for STM32 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 STM32 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
After pressing the "FLASH" button on the left-side panel, it is necessary to open the UART terminal to display the achieved results. By clicking on the Tools icon in the right-hand panel, multiple different functions are displayed, among which is the UART Terminal. Click on the offered "UART Terminal" icon.
Once the UART terminal is opened, the window takes on a new form. At the top of the tab are two buttons, one for adjusting the parameters of the UART terminal and the other for connecting the UART terminal. The tab's lower part is reserved for displaying the achieved results. Before connecting, the terminal has a Disconnected status, indicating that the terminal is not yet active. Before connecting, it is necessary to check the set parameters of the UART terminal. Click on the "OPTIONS" button.
In the newly opened UART Terminal Options field, we check if the terminal settings are correct, such as the set port and the Baud rate of UART communication. If the data is not displayed properly, it is possible that the Baud rate value is not set correctly and needs to be adjusted to 115200. If all the parameters are set correctly, click on "CONFIGURE".
The next step is to click on the "CONNECT" button, after which the terminal status changes from Disconnected to Connected in green, and the data is displayed in the Received data field.

* \brief Shuttle Click example
*
* # Description
* This example showcases how to initialize, configure and use the Terminal click. It is a simple
* GPIO click which uses high-quality PCB design, four ICD BOX headers and flat ribbon cables to
* enable stable communication and easy stacking of other click modules.
*
* The demo application is composed of two sections :
*
* ## Application Init
* This function initializes and configures the click and logger modules.
*
* ## Application Task
* This function sets the output on all the pins (one by one) on the left side to high, going
* from top to bottom and then does the same with the ones on the right side, after which it
* sets all pins to high and after one second sets them back to low.
