IR distance click

IR distance click carries Sharp’s GP2Y0A60SZ0F distance measuring sensor, which comprises of an integrated PSD (position sensitive detector), an infrared LED and a signal processing circuit. The measuring range is between 10 and 150 cm. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target MCU over RST and AN pin on the mikroBUS™ line.

Click library

Software Support

We provide a library for the IrDistance 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 IrDistance Click driver.

Standard key functions :

Example key functions :

Examples Description

The click board outputs an analog voltage corresponding to the distance of the object (through the mikroBUS AN pin). An Enable (EN) pin is also utilized.

The demo application is composed of two sections :

Application Init

Initialization driver enables GPIO, enable IR sensor, initialization ADC, also 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.
IRDISTANCE_MAP_MIKROBUS( cfg, MIKROBUS_1 );
irdistance_init( &irdistance, &cfg );
irdistance_default_cfg ( &irdistance );
}

Application Task

This is an example which demonstrates the use of IR Distance click board. IR Distance click reads and displays ADC value. Results are being sent to the Usart Terminal where you can track their changes. All data logs on USB uart change for every 1 sec.

void application_task ( void )
{
adc_val = irdistance_read_adc( &irdistance );
log_printf( &logger, " ADC value : %u\r\n", adc_val );
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.
