Library Description

The library contains basic functions to perform the control of the Magneto 8 click board.

Key functions:

• uint16_t magneto8_get_angle_data ( void ) - Gets Angle data
• uint16_t magneto8_get_magnitude ( void ) - Gets magnitude data
• uint8_t magneto8_get_status ( void ) - Gets status data

Examples description

The application is composed of three sections :

• System Initialization - Initialize the I2C module and all necessary GPIO pins
• Application Initialization - Initializes driver init and starts config module for measurement
• Application Task - Reads angle and magnetic data. Logs data every 2 seconds

void application_task ( )
{
    uint16_t angle;
    uint16_t mag;
    char demo_text[ 20 ];

    mag  = magneto8_get_magnitude( );
    IntToStr( mag, demo_text );
    mikrobus_logWrite( "Magnetic: ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_LINE );
    
    angle = magneto8_get_angle_data( );
    IntToStr( angle, demo_text );
    mikrobus_logWrite( "Angle : ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_LINE );

    mikrobus_logWrite( "----------------------", _LOG_LINE );
    Delay_ms( 2000 );
}

Other mikroE Libraries used in the example:

• I2C Library
• UART Library

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.
