Hardware Overview
How does it work?
Tester Click is a Click board™ used as a diagnostic tool on the mikroBUS™ socket. It contains an array of 2x6 LEDs, which signalize the presence of the HIGH/LOW logic level on each pin, providing a visual feedback to the developer. Two additional LEDs indicate the presence of +3.3V and +5V on the mikroBUS™ power rails. This simple diagnostic tool can save hours of troubleshooting, saving the
application developer from having to connect various complicated measurement instruments, only to test logic states on the specific mikroBUS™ pins. Each pin of the mikroBUS™ is routed to a red colored LED, which is protected by 1K resistor. This allows voltages up to VCC to be handled with no issues, providing a simple and clean solution for pin state testing. Once placed on the mikroBUS™
socket, no additional settings are required. There are no ICs or other active elements besides the LEDs. Its simplicity makes it very simple to use: as soon as it is connected, red and green power indication LEDs will signalize the presence of +3.3V and +5V on both the mikroBUS™ power rails. The rest of the LED array will be lit according to the state on the respective pin.
Features overview
Development board
UNI Clicker is a compact development board designed as a complete solution that brings the flexibility of add-on Click boards™ to your favorite microcontroller, making it a perfect starter kit for implementing your ideas. It supports a wide range of microcontrollers, such as different ARM, PIC32, dsPIC, PIC, and AVR from various vendors like Microchip, ST, NXP, and TI (regardless of their number of pins), four mikroBUS™ sockets for Click board™ connectivity, a USB connector, LED indicators, buttons, a debugger/programmer connector, and two 26-pin headers for interfacing with external electronics. Thanks to innovative manufacturing technology, it allows you to build
gadgets with unique functionalities and features quickly. Each part of the UNI Clicker development kit contains the components necessary for the most efficient operation of the same board. In addition to the possibility of choosing the UNI Clicker programming method, using a third-party programmer or CODEGRIP/mikroProg connected to onboard JTAG/SWD header, the UNI Clicker board also includes a clean and regulated power supply module for the development kit. It provides two ways of board-powering; through the USB Type-C (USB-C) connector, where onboard voltage regulators provide the appropriate voltage levels to each component on the board, or using a Li-Po/Li
Ion battery via an onboard battery connector. All communication methods that mikroBUS™ itself supports are on this board (plus USB HOST/DEVICE), including the well-established mikroBUS™ socket, a standardized socket for the MCU card (SiBRAIN standard), and several user-configurable buttons and LED indicators. UNI Clicker is an integral part of the Mikroe ecosystem, allowing you to create a new application in minutes. Natively supported by Mikroe software tools, it covers many aspects of prototyping thanks to a considerable number of different Click boards™ (over a thousand boards), the number of which is growing every day.

Application Output
After loading the code example, pressing the "DEBUG" button builds and programs it on the selected setup.
After programming is completed, a header with buttons for various actions available in the IDE appears. By clicking the green "PLAY "button, we start reading the results achieved with Click board™.
Upon completion of programming, the Application Output tab is automatically opened, where the achieved result can be read. In case of an inability to perform the Debug function, check if a proper connection between the MCU used by the setup and the CODEGRIP programmer has been established. A detailed explanation of the CODEGRIP-board connection can be found in the CODEGRIP User Manual. Please find it in the RESOURCES section.

*
* # Description
* This example showcases how to initialize, configure and use the Tester click. It is a simple
* GPIO click which is used to test if all the pins on a MikroBUS are working correctly.
*
* 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.
