7x10 Y 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.

We provide a library for the c7x10Y 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.
This library contains API for c7x10Y Click driver.
c7x10y_cfg_setup
Config Object Initialization function.
void c7x10y_cfg_setup ( c7x10y_cfg_t *cfg );
c7x10y_init
Initialization function.
c7x10y_return_value_t c7x10y_init ( c7x10y_t *ctx, c7x10y_cfg_t *cfg );
c7x10y_draw_pixel
Drawing the pixel on the display.
void c7x10y_draw_pixel ( c7x10y_t *ctx, c7x10y_pixel_t *pixel, uint8_t mode, uint8_t px_delay );
c7x10y_draw_char
Drawing the character on the display.
void c7x10y_draw_char ( c7x10y_t *ctx, char ch, uint8_t pos, uint8_t ch_delay );
c7x10y_draw_number
Drawing the number on the display.
void c7x10y_draw_number ( c7x10y_t *ctx, uint8_t num, uint16_t num_delay );
This demo example shows a drawing of pixels, characters and a number on the screen.
The demo application is composed of two sections :
Configuring the Click board.
void application_init ( void ) {
c7x10y_cfg_t c7x10y_cfg; /**< Click config object. */
// Click initialization.
c7x10y_cfg_setup( &c7x10y_cfg );
C7X10Y_MAP_MIKROBUS( c7x10y_cfg, MIKROBUS_1 );
c7x10y_init( &c7x10y, &c7x10y_cfg );
}
Draws characters, numbers, and pixels to the display.
void application_task ( void ) {
c7x10y_pixel_t pixel;
uint8_t cnt;
uint8_t cnt_x;
uint8_t cnt_y;
// CHAR PROCEDURE
for ( cnt = 'A'; cnt < 'Z'; cnt+=2 ) {
c7x10y_draw_char( &c7x10y, cnt, C7X10Y_DISPLAY_LEFT, C7X10Y_DISPLAY_DELAY_50MS );
c7x10y_draw_char( &c7x10y, cnt + 1, C7X10Y_DISPLAY_RIGHT | C7X10Y_DISPLAY_REFRESH, C7X10Y_DISPLAY_DELAY_50MS );
Delay_ms ( 1000 );
}
// COUNTER PROCEDURE
for ( cnt = 0; cnt < 15; cnt++ ) {
c7x10y_draw_number( &c7x10y, cnt, C7X10Y_DISPLAY_DELAY_50MS );
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;
c7x10y_draw_pixel( &c7x10y, &pixel, C7X10Y_DISPLAY_PIXEL_STORAGE, C7X10Y_DISPLAY_DELAY_20MS );
pixel.cord_x = cnt_x;
pixel.cord_y = cnt_y + 1;
c7x10y_draw_pixel( &c7x10y, &pixel, C7X10Y_DISPLAY_PIXEL_REFRESH, C7X10Y_DISPLAY_DELAY_20MS );
}
}
}

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.
