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
PIC18F47K42 Curiosity Nano evaluation kit is a cutting-edge hardware platform designed to evaluate the PIC18F47K42 microcontroller (MCU). Central to its design is the inclusion of the powerful PIC18F47K42 microcontroller (MCU), offering advanced functionalities and robust performance. Key features of this evaluation kit include a yellow user LED and a responsive mechanical user switch
providing seamless interaction and testing. The provision for a 32.768kHz crystal footprint ensures precision timing capabilities. With an onboard debugger boasting a green power and status LED, programming and debugging become intuitive and efficient. Further enhancing its utility is the Virtual serial port (CDC) and a debug GPIO channel (DGI GPIO), offering extensive connectivity options.
Powered via USB, this kit boasts an adjustable target voltage feature facilitated by the MIC5353 LDO regulator, ensuring stable operation with an output voltage ranging from 2.3V to 5.1V (limited by USB input voltage), with a maximum output current of 500mA, subject to ambient temperature and voltage constraints.

Application Output
After loading the code example, pressing the "DEBUG" button builds and programs it on the selected setup.
![Application Output Step 1](https://dbp-cdn.mikroe.com/cms/shared-resources/1eed554e-d80f-6694-8cb9-02420a000272/AP-Step1.jpg)
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™.
![Application Output Step 3](https://dbp-cdn.mikroe.com/cms/shared-resources/1eed5550-3c0f-6800-a19f-02420a000272/AP-Step3.jpg)
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.

* @file main.c
* @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.
