IR Gesture click

IR Gesture Click is a mikroBUS add-on board that enables contactless gesture recognition, along with ambient light and proximity sensing capabilities with the APDS-9960 IC. This sensor integrates an LED and four directional photodiodes that receive the reflecting light.

Click library

Software Support

We provide a library for the IrGesture 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for IrGesture Click driver.

Standard key functions :

Example key functions :

Examples Description

This Click enables contactless gesture recognition: basic directional swipes (up, down, left or right).

The demo application is composed of two sections :

Application Init

Initialization driver enable's - I2C, set default configuration, enable geasture sensor and start write log.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
IRGESTURE_MAP_MIKROBUS( cfg, MIKROBUS_1 );
irgesture_init( &irgesture, &cfg );
irgesture_default_cfg( &irgesture );
}

Application Task

This is a example which demonstrates the use of IR Gesture Click board. IR Gesture Click detects gestures and sends the movement to terminal every 1 second.

void application_task ( void )
{
position = irgesture_detect_gesture( &irgesture );
if ( position_old != position )
{
if ( position == IRGESTURE_FAR )
{
log_printf( &logger, " F A R \r\n" );
}
if ( position == IRGESTURE_RIGHT )
{
log_printf( &logger, " R I G H T \r\n" );
}
if ( position == IRGESTURE_LEFT )
{
log_printf( &logger, " L E F T \r\n" );
}
if ( position == IRGESTURE_UP )
{
log_printf( &logger, " U P \r\n" );
}
if ( position == IRGESTURE_DOWN )
{
log_printf( &logger, " D O W N \r\n" );
}
if ( position == IRGESTURE_NEAR )
{
log_printf( &logger, " N E A R \r\n" );
}
position_old = position;
log_printf( &logger, "--------------------\r\n" );
Delay_ms( 1000 );
}
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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.
