Hardware Overview
How does it work?
10x10 RGB 2 Click is based on the IN-PC20TBT5R5G5B, an RGB LED with integrated IC from Inolux. At its core, the 10x10 RGB 2 Click showcases a dynamic grid of 100 "smart" RGB LEDs configured into a compact 10x10 display. These LEDs stand out for their dual-wire transmission capability, encompassing a three-channel (RGB) smart control circuit for driving and illumination. Noteworthy features include a signal decoding module, a data buffering system, an inbuilt constant current circuit, and an RC oscillator. The whole solution is tailor-made for various applications, such as LED-based display screens, vibrant LED string lighting, and ambient scene illumination. The IN-PC20TBT5R5G5B is made with
CMOS technology, ensuring minimal voltage requirements and reduced power consumption. It supports 256 grayscale levels for PWM dimming and offers 32 levels of brightness control. The RGB LEDs on the board exhibit distinct characteristics for each color: the red LED operates within a wavelength range of 620-630nm and delivers a light intensity between 100-200mcd, the green LED features a wavelength span of 520-530nm with a brightness of 300-500mcd, and the blue LED emits light in the 460-475nm range with an intensity ranging from 50-100mcd. The diodes are designed to function exclusively on a 5V supply sourced from the mikroBUS™ 5V power rail. To accommodate this, their control is managed through the LSD0102,
a bidirectional voltage-level translator from Texas Instruments. This design choice ensures compatibility with both 3.3V and 5V MCUs, enhancing the board's versatility. A special feature of these diodes is the existence of two output signals, data, and clock, routed on test points next to 5V and GND test points on the back of the board. This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC 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
EasyAVR v7 is the seventh generation of AVR development boards specially designed for the needs of rapid development of embedded applications. It supports a wide range of 16-bit AVR microcontrollers from Microchip and has a broad set of unique functions, such as a powerful onboard mikroProg programmer and In-Circuit debugger over USB. The development board is well organized and designed so that the end-user has all the necessary elements in one place, such as switches, buttons, indicators, connectors, and others. With four different connectors for each port, EasyAVR v7 allows you to connect accessory boards, sensors, and custom electronics more
efficiently than ever. Each part of the EasyAVR v7 development board contains the components necessary for the most efficient operation of the same board. An integrated mikroProg, a fast USB 2.0 programmer with mikroICD hardware In-Circuit Debugger, offers many valuable programming/debugging options and seamless integration with the Mikroe software environment. Besides it also includes a clean and regulated power supply block for the development board. It can use a wide range of external power sources, including an external 12V power supply, 7-12V AC or 9-15V DC via DC connector/screw terminals, and a power source via the USB Type-B (USB-B)
connector. Communication options such as USB-UART and RS-232 are also included, alongside the well-established mikroBUS™ standard, three display options (7-segment, graphical, and character-based LCD), and several different DIP sockets which cover a wide range of 16-bit AVR MCUs. EasyAVR v7 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
After pressing the "FLASH" button on the left-side panel, it is necessary to open the UART terminal to display the achieved results. By clicking on the Tools icon in the right-hand panel, multiple different functions are displayed, among which is the UART Terminal. Click on the offered "UART Terminal" icon.
Once the UART terminal is opened, the window takes on a new form. At the top of the tab are two buttons, one for adjusting the parameters of the UART terminal and the other for connecting the UART terminal. The tab's lower part is reserved for displaying the achieved results. Before connecting, the terminal has a Disconnected status, indicating that the terminal is not yet active. Before connecting, it is necessary to check the set parameters of the UART terminal. Click on the "OPTIONS" button.
In the newly opened UART Terminal Options field, we check if the terminal settings are correct, such as the set port and the Baud rate of UART communication. If the data is not displayed properly, it is possible that the Baud rate value is not set correctly and needs to be adjusted to 115200. If all the parameters are set correctly, click on "CONFIGURE".
The next step is to click on the "CONNECT" button, after which the terminal status changes from Disconnected to Connected in green, and the data is displayed in the Received data field.

* @brief 10x10 RGB 2 Click example
*
* # Description
* This example demonstrates the use of the 10x10 RGB 2 click board by showing
* a practical example of using the implemented functions.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes the driver and performs the click default configuration.
*
* ## Application Task
* Displays digits 0-9 first, then writes RGB chars and demonstrates the rotation of characters.
* After that, scrolls the text, displays the MIKROE logo image, and showcases a rainbow demo.
* All data is logged on the USB UART where you can track the program flow.
