Hardware Overview
How does it work?
7-SEG RGB Click is based on the 160100-71, a full-color single 7-segment digit display from Elektor. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over the CS, and PWM pin on the mikroBUS™ line. The click can be connected in a chain, in order to display a larger number of characters. Unlike with conventional 7
segment displays, you will be able to use multiple colors on the display. Each segment has R, G, B LEDs that can be adjusted in 255 steps and therefore 16,581,375 color combinations are available for each segment of the digit on the display. Also, the ability to control the brightness of all the LED's is driven at 255 steps. It should be noted that the brightness values above 80 should
rarely be used. This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the LOGIC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. 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
Clicker 2 for Kinetis is a compact starter development board 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 ARM Cortex-M4F microcontroller, the MK64FN1M0VDC12 from NXP Semiconductors, two mikroBUS™ sockets for Click board™ connectivity, a USB connector, LED indicators, buttons, a JTAG programmer connector, and two 26-pin headers for interfacing with external electronics. Its compact design with clear and easily recognizable silkscreen markings allows you to build gadgets with unique functionalities and
features quickly. Each part of the Clicker 2 for Kinetis development kit contains the components necessary for the most efficient operation of the same board. In addition to the possibility of choosing the Clicker 2 for Kinetis programming method, using a USB HID mikroBootloader or an external mikroProg connector for Kinetis programmer, the Clicker 2 board also includes a clean and regulated power supply module for the development kit. It provides two ways of board-powering; through the USB Micro-B cable, where onboard voltage regulators provide the appropriate voltage levels to each component on the board, or
using a Li-Polymer battery via an onboard battery connector. All communication methods that mikroBUS™ itself supports are on this board, including the well-established mikroBUS™ socket, reset button, and several user-configurable buttons and LED indicators. Clicker 2 for Kinetis 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 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 7-SEG RGB Click example
*
* # Description
* This click shows all ten digits on a full-color single 7 segment digit display.
* Each segment has R, G, B LEDs that can be adjusted in 255 steps and
* the ability to control the brightness of all the LED.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initialization driver enables - GPIO.
*
* ## Application Task
* This is an example which demonstrates the use of 7-SEG RGB Click board.
* This simple example shows all ten digits in different colors on 7-SEG RGB click.
*
* @note
* Make sure the logic delays are defined for your system in the c7segrgb_delays.h file.
*
* <pre>
* Additional Functions :
* void logic_one ( ) - Generic logic one function.
* void logic_zero ( ) - Generic logic zero function.
