Click library

Software Support

We provide a library for the Proximity8 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 Proximity8 Click driver.

Standard key functions :

Example key functions :

Examples Description

This application enables usage of the proximity sensor

The demo application is composed of two sections :

Application Init

Initialization Driver init, test comunication and configuration chip for measurement

void application_init ( void )
{
log_cfg_t log_cfg;
uint16_t tmp;
uint16_t w_temp;
// 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.
PROXIMITY8_MAP_MIKROBUS( cfg, MIKROBUS_1 );
proximity8_init( &proximity8, &cfg );
//Test Communication
if( tmp == PROXIMITY8_DEVICE_ID )
{
log_printf( &logger, "---- Comunication OK!!! ----\r\n" );
}
else
{
log_printf( &logger, "---- Comunication ERROR!!! ----\r\n" );
while( 1 );
}
proximity8_default_cfg( &proximity8 );
log_printf( &logger, "---- Start measurement ----\r\n" );
}

Application Task

Reads Proximity data and this data logs to the USBUART every 1500ms.

void application_task ( void )
{
// Task implementation.
uint16_t proximity;
proximity = ( proximity & 0x7FFF );
log_printf( &logger, " Proximity data: %d\r\n", proximity );
log_printf( &logger, "-------------------------\r\n" );
Delay_ms( 1500 );
}

Note

The reading value and proximity of the data depend on the configuration.

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.
