Click library

Software Support

We provide a library for the Pressure7 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 Pressure7 Click driver.

Standard key functions :

Example key functions :

Examples Description

This example reads temperature and pressure and logs it every 3 seconds.

The demo application is composed of two sections :

Application Init

Initialize Logger and Click object and call pressure7_read_PROM() function.

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.
PRESSURE7_MAP_MIKROBUS( cfg, MIKROBUS_1 );
pressure7_init( &pressure7, &cfg );
pressure7_default_cfg ( &pressure7 );
// Read calibrated data from the PROM
prom_exit_value = pressure7_read_PROM( &pressure7 );
if ( prom_exit_value == PRESSURE7_PROM_READ_OK )
{
log_info( &logger, "Read PROM - OK !\r\n" );
}
else
{
log_info( &logger, "Read PROM - ERROR!\r\n" );
}
Delay_ms( 100 );
}

Application Task

Get sensor data on every 3 seconds and send measured temperature and pressure to logger.

void application_task ( void )
{
pressure7_get_sensor_data( &pressure7, &Temperature, &Pressure );
log_printf( &logger, "Temperature: %fC\r\n", Temperature );
log_printf( &logger, "Pressure: %f\r\n", Pressure );
Delay_ms( 3000 );
}

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.
