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
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 via UART Mode
1. Once the code example is loaded, pressing the "FLASH" button initiates the build process, and programs it on the created setup.
2. After the programming is completed, click on the Tools icon in the upper-right panel, and select the UART Terminal.
3. After opening the UART Terminal tab, first check the baud rate setting in the Options menu (default is 115200). If this parameter is correct, activate the terminal by clicking the "CONNECT" button.
4. Now terminal status changes from Disconnected to Connected in green, and the data is displayed in the Received data field.

* \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.
