8x8 G Click Board
8x8 G Click Board
Introduce a green serial 8x8 LED matrix display to your design with the 8x8 G Click Board™. This display add-on board in the MikroBUS form factor incorporates an 8-digit MAX7219 LED display driver module as well as 64 (8x8) green-coloured LEDs. This clock board is designed to communicate with the target board MCU through four MikroBUS SPI lines (DIN, DOUT, CLK and CS).
The serially-interfaced MAX7219 LED display driver features an on-chip BCD code-B decoder, digital and analogue brightness control, and an 8x8 static RAM that stores each digit. the 8x8 G Click Board™ makes an ideal choice for bar graph displays, industrial controllers, led matrix displays, and panel meters. It is available in a range of other colour options including red, blue, and yellow.
Software Support
We provide a library for the 8x8 G Click Board™ on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers and mikroSDK. The provided click library is mikroSDK standard compliant. The demo application can run on all the main MikroElektronika development boards.
Library Description
The library provides generic functions for controlling the Click board™.
Key functions:
void c8x8g_writeReg(uint8_t Reg, uint8_t Value);
- Function for writing data to a register.void c8x8g_writeText(uint8_t *pStr, uint8_t nLenght);
- Scrolls provided text.
Examples Description
The application is composed of three sections:
- System Initialization - Initializes CS pin as output and SPI module
- Application Initialization - Driver initialization and default configuration of the 8x8 click board.
- Application Task - (code snippet) - Sequential writing of provided string each one second.
void applicationTask() { c8x8b_displayWord(&demoString[0]); Delay_1sec(); }
The full application code, and ready to use projects can be found on our LibStock page.
Other mikroE Libraries used in the example:
- Conversions Library
- C_String Library
- SPI Library
Additional Notes and Information
Depending on the development board you are using, you may need a USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
MIKROSDK
The 8x8 G Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant click board demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
