Hardware Overview
How does it work?
Terminal Click consists of a high-quality PCB that can be connected to the mikroBUS™ as any other click board. On the top of the Terminal click, a 2x8 pin header is placed. Each of the header pins is corresponding to a pin on the mikroBUS™ being used. These are simply wired in parallel. Thanks to the stacking headers, the connection with the click board™ remains firm and stable. Besides . Having this kind of stacking topology, allows for easy pin access and manipulation of the stacked click boards™, retaining a perfect connection quality at all times. When there's a need to attach
external equipment to the development system, the desired mikroBUS™ socket can be populated with Terminal click, allowing even more connections. This makes the stacking capacity almost unlimited. However, attention should be paid not to make the lines attached to the mikroBUS™ too long. In situations like this, the frequency of the communication might need to be stepped down a bit, in order to compensate for the longer mikroBUS™ signal lines. Lines of the mikroBUS™ to which Terminal click is attached, are shared through the top 16-pin header, which
mirrors pins of the connected mikroBUS™. Therefore, a care should be taken when working with the Terminal click and connecting an external device to it, because the same pins on the mikroBUS™ are shared, either for the communication (SPI, UART, I2C) or for some other purpose (RST, INT, or other pins used as GPIO). Since all the stacked click boards™ share the same power rails, a Terminal click also shares the power rails, which makes it compatible with any click board™ and development systems.
Features overview
Development board
UNI-DS 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 STM32, Kinetis, TIVA, CEC, MSP, PIC, dsPIC, PIC32, and AVR MCUs 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, UNI-DS v8 provides a fluid and immersive working experience, allowing access anywhere and under any
circumstances at any time. Each part of the UNI-DS 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. UNI-DS 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.
Software Support
Library Description
This library contains API for Terminal Click driver.
Key functions:
terminal_set_pin_high- This function sets the output voltage on the specified pin to high.terminal_set_pin_low- This function sets the output voltage on the specified pin to low.

* # Description
* This example showcases how to initialize, configure and use the Terminal click. It is a simple
* GPIO click which is used like an adapter for connecting and stacking other clicks and external
* equimpent.
*
* 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.
