7x10 B click

7x10 B click is a LED dot matrix display click, which can be used to display graphics or letters in a very simple and easy way. The click board has two LED dot matrix modules with 7x5 stylish, round, dot-like LED elements. These displays produce clean and uniform patterns since the elements are optically isolated from each other and there is no light bleeding between the adjacent LED cells. Additionally, turn-on and turn-off times of the matrix cells are optimized for a clean and fluid display performance, with no flickering or lag.

Software Support

We provide a library for the c7x10B Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for c7x10B Click driver.

Standard key functions :

Example key functions :

Example Description

This demo example shows a drawing of pixels, characters and a number on the screen.

The demo application is composed of two sections :

Application Init

Configuring the click board.

void application_init ( void ) {
c7x10b_cfg_t c7x10b_cfg;
// Click initialization.
c7x10b_cfg_setup( &c7x10b_cfg );
C7X10B_MAP_MIKROBUS( c7x10b_cfg, MIKROBUS_1 );
c7x10b_init( &c7x10b, &c7x10b_cfg );
}

Application Task

Draws characters, numbers, and pixels to the display.

void application_task ( void ) {
uint8_t cnt;
uint8_t cnt_x;
uint8_t cnt_y;
// CHAR PROCEDURE
for ( cnt = 'A'; cnt < 'Z'; cnt+=2 ) {
Delay_ms( 1000 );
}
// COUNTER PROCEDURE
for ( cnt = 0; cnt < 15; cnt++ ) {
Delay_ms( 500 );
}
// PIXELS PROCEDURE
for ( cnt_x = 0; cnt_x <= 7; cnt_x++ ) {
for ( cnt_y = 0; cnt_y <= 10; cnt_y++ ) {
pixel.cord_x = cnt_x;
pixel.cord_y = cnt_y;
pixel.cord_x = cnt_x;
pixel.cord_y = cnt_y + 1;
}
}
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.c7x10B

Additional notes and informations

Depending on the development board you are using, you may need 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.
