Magneto 11 click

Magneto 11 Click is a compact add-on board that contains an accurate and reliable magnetic sensing device. This board features the AS5510, a linear hall sensor with 10-bit resolution, and an I2C interface from ams AG. It can measure the absolute position of lateral movement of a simple 2-pole magnet. A lateral stroke of 0.5mm ~ 2mm can be measured with air gaps around 1.0mm, depending on the magnet size. The AS5510 may be switched to a Power-Down state when it is not used to conserve power. This Click boardâ„¢ is suitable for position sensing applications requiring a small magnetic range where noise is a critical design parameter.

  • Date : Jan 2022.
  • Type : I2C type

Software Support

We provide a library for the Magneto 11 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Magneto 11 Click driver.

Example Description

This example demonstrates the use of Magneto 11 click board by reading and displaying the magnetic field strength value.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
magneto11_cfg_t magneto11_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
magneto11_cfg_setup( &magneto11_cfg );
MAGNETO11_MAP_MIKROBUS( magneto11_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == magneto11_init( &magneto11, &magneto11_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( MAGNETO11_ERROR == magneto11_default_cfg ( &magneto11 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Reads the magnetic field strength value in milliTesla and displays the results on the USB UART every 200ms approximately.

void application_task ( void )
{
float magnetic_field;
if ( MAGNETO11_OK == magneto11_get_magnetic_field ( &magneto11, &magnetic_field ) )
{
log_printf ( &logger, " Magnetic Field: %.3f mT \r\n\n", magnetic_field );
Delay_ms ( 200 );
}
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Magneto11

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. UART terminal is available in all MikroElektronika compilers.
