Hardware Overview
How does it work?
AlphaNum R Click is based on one red two digits 14-segment alphanumeric display with leading dots and two TLC5926s, 16-bit constant-current LED-sink drivers from Texas Instruments. This display consists of two sets of 14 LEDs arranged in a rectangular starburst fashion, where each of the 14 LEDs is called a segment. The segment forms part of a numerical digit (decimal and hex) or ISO basic Latin alphabet to be displayed when illuminated. The fifteenth segment of each set is a comma, suitable for displaying a decimal number. Two TLC5926s drive this display with constant currents in the sink configuration. The TLC5926 is a
256-step programmable global current gain with constant current adjusted by an external resistor; in this case, it is kept around 8mA per segment. This Click board™ uses the SPI serial interface of the mikroBUS™ socket to communicate with the host MCU. There are four additional pins, two for each TLC5926: data latch pins marked as LE1 and LE2, routed to the CS and RST pins of the mikroBUS™ socket, and display segment select pins labeled as NS and NS# routed to the INT and PWM pins of the mikroBUS™ socket. Those latch pins are data strobe input pins where serial data is transferred to the respective latch when they are
in a high logic state. The data is latched when those pins are in a low logic state. Output enable pins are active LOW with enabled output drivers; otherwise, with a high state, the display is turned OFF. This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the PWR SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. 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.
Features overview
Development board
Flip&Click PIC32MZ 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 comes with an onboard 32-bit PIC32MZ microcontroller, the PIC32MZ2048EFH100 from Microchip, four mikroBUS™ sockets for Click board™ connectivity, two USB connectors, LED indicators, buttons, debugger/programmer connectors, and two headers compatible with Arduino-UNO pinout. Thanks to innovative manufacturing technology,
it allows you to build gadgets with unique functionalities and features quickly. Each part of the Flip&Click PIC32MZ development kit contains the components necessary for the most efficient operation of the same board. In addition, there is the possibility of choosing the Flip&Click PIC32MZ programming method, using the chipKIT bootloader (Arduino-style development environment) or our USB HID bootloader using mikroC, mikroBasic, and mikroPascal for PIC32. This kit includes a clean and regulated power supply block through the USB Type-C (USB-C) connector. All communication
methods that mikroBUS™ itself supports are on this board, including the well-established mikroBUS™ socket, user-configurable buttons, and LED indicators. Flip&Click PIC32MZ development kit allows 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 via Debug Mode
1. Once the code example is loaded, pressing the "DEBUG" button initiates the build process, programs it on the created setup, and enters Debug mode.
2. After the programming is completed, a header with buttons for various actions within the IDE becomes visible. Clicking the green "PLAY" button starts reading the results achieved with the Click board™. The achieved results are displayed in the Application Output tab.

* @brief AlphaNumR Click example
*
* # Description
* This example showcases the initialization and configuration of the logger and click modules
* and shows how to display characters and numbers on both LED segments of the click.
*
* The demo application is composed of two sections :
*
* ## Application Init
* This function initializes and configures the logger and click modules.
*
* ## Application Task
* This function sets the time interval at which the symbols are displayed on the LED
* segments and shows a few characters and numbers.
