Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : SPI type

Software Support

We provide a library for the Magneticlinear 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 Magneticlinear Click driver.

Standard key functions :

Example key functions :

  • This function reads Magnetics Linear data.

    uint16_t magneticlinear_read_data ( magneticlinear_t *ctx );

Examples Description

This application reads magnetics linear data.

The demo application is composed of two sections :

Application Init

Device initialization.

void application_init ( void )
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
MAGNETICLINEAR_MAP_MIKROBUS( cfg, MIKROBUS_1 );
magneticlinear_init( &magneticlinear, &cfg );
}

Application Task

Reads magnetic linear data and logs it to USB UART every 500ms.

void application_task ( void )
{
uint16_t magnetic_data;
magnetic_data = magneticlinear_read_data( &magneticlinear );
log_printf( &logger, " Magnetic Linear data : %u\r\n", magnetic_data );
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.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Magneticlinear

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.
