Terminal 2 Click Board™

Product Code: MIKROE-4951

How Does The Terminal 2 Click Board™ Work? The Terminal 2 Click Board™ is an adapter 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 Board™, 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 mirrors 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).

The Terminal 2 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, labelled as PWR. However, the 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.

The demo can run on all the main MikroElektronika development boards. The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on Mikroe Github account. Library Description This library contains API for the Terminal 2 Click Board™ 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. Example Description This example demonstates the use of the Terminal 2 Click Board™ by toggling all its pins. void application_task ( void ) { /**< Array of pins object addresses. */ static di
