Hardware Overview
How does it work?
Terminal 2 Click is an adapter Click board™ used as a mikroBUS™ socket expansion board. This Click board™ provides an easy and elegant solution for adding the external connection capability to the Click board™ and can be connected to the mikroBUS™ socket like any other Click board™. On the central area of the Terminal 2 Click, two 9-position 2.54mm pitch terminal blocks are placed. Each of the terminal pins corresponds to a pin on the mikroBUS™ socket. Thanks to these terminals, the connection
with the Click board™ remains firm and stable, retaining a perfect connection quality at all times. Lines of the mikroBUS™ socket to which Terminal 2 Click is attached are shared through the onboard connectors, which mirror the connected mikroBUS™ socket pins. Therefore, care should be taken when working with the Terminal 2 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). This Click board™ can operate with both 3.3V and 5V logic voltage levels. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. A green LED visually detects the presence of an active power supply labeled as PWR. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
Features overview
Development board
EasyPIC v8 is a development board specially designed for the needs of rapid development of embedded applications. It supports many high pin count 8-bit PIC microcontrollers from Microchip, regardless of their number of pins, and a broad set of unique functions, such as the first-ever embedded debugger/programmer. 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, EasyPIC v8 provides a fluid and immersive working experience, allowing access anywhere and under any
circumstances at any time. Each part of the EasyPIC v8 development board contains the components necessary for the most efficient operation of the same board. In addition to the advanced integrated CODEGRIP programmer/debugger module, which offers many valuable programming/debugging options and seamless integration with the Mikroe software environment, the board 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 DEVICE, and CAN are also included, including the well-established mikroBUS™ standard, two display options (graphical and character-based LCD), and several different DIP sockets. These sockets cover a wide range of 8-bit PIC MCUs, from the smallest PIC MCU devices with only eight up to forty pins. EasyPIC 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
1. Application Output - In Debug mode, the 'Application Output' window enables real-time data monitoring, offering direct insight into execution results. Ensure proper data display by configuring the environment correctly using the provided tutorial.
2. UART Terminal - Use the UART Terminal to monitor data transmission via a USB to UART converter, allowing direct communication between the Click board™ and your development system. Configure the baud rate and other serial settings according to your project's requirements to ensure proper functionality. For step-by-step setup instructions, refer to the provided tutorial.
3. Plot Output - The Plot feature offers a powerful way to visualize real-time sensor data, enabling trend analysis, debugging, and comparison of multiple data points. To set it up correctly, follow the provided tutorial, which includes a step-by-step example of using the Plot feature to display Click board™ readings. To use the Plot feature in your code, use the function: plot(*insert_graph_name*, variable_name);. This is a general format, and it is up to the user to replace 'insert_graph_name' with the actual graph name and 'variable_name' with the parameter to be displayed.
Software Support
Library Description
This library contains API for Terminal 2 Click driver.
Key functions:
terminal2_set_all_pins_high- This function sets all terminal pins to high logic level.terminal2_set_all_pins_low- This function sets all terminal pins to low logic level.terminal2_toggle_pin- This function toggles the specified pin logic level.
Open Source
Code example
The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.

* @file main.c
* @brief Terminal 2 Click Example.
*
* # Description
* This example demonstates the use of Terminal 2 Click board by toggling all its pins.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes the driver and logger and sets all pins to low logic state.
*
* ## Application Task
* Toggles all pins from mikroBUS one by one in the span of 1 second between each pin toggle.
