Click library

Software Support

We provide a library for the Pressure4 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 Pressure4 Click driver.

Standard key functions :

Example key functions :

Examples Description

This app measure barometric pressure.

The demo application is composed of two sections :

Application Init

Initializes the click board.

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 ----\r\n" );
// Click initialization.
PRESSURE4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
pressure4_init( &pressure4, &cfg );
pressure4_default_cfg( &pressure4 );
Delay_ms( 100 );
}

Application Task

The preassure and temperature data is read from the sensor and it is printed to the UART.

void application_task ( void )
{
double tmp;
tmp = pressure4_get_temperature( &pressure4 );
log_printf( &logger, "Temperature : %lf \r\n", tmp );
tmp = pressure4_get_pressure( &pressure4 );
log_printf( &logger, "Pressure : %lf hPa \r\n", tmp );
log_printf( &logger, "========================\r\n", tmp );
Delay_ms( 500 );
}

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.
