Software Support

We provide a library for the 3D_Hall_3 Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

The library initializes and defines the I2C bus or SPI bus driver and drivers that offer a choice for writing data in registers and reading data from registers. The library includes function for read X/Y/Z axis data, set offset, read interrupt state. The user also has the function for configuration chip.

Key functions :

• void c3dhall3_readXYZ( int16_t *OUT_XYZ ) - Reading X Y Z - axes values
• void c3dhall3_configuration( void ) - Click default configuration
• void c3dhall3_writeOffset(uint8_t axis, uint16_t offset ) -Writing X Y or Z-axis offset

Examples Description

The application is composed of three sections :

• System Initialization - Initializes I2C communication, INT pin as input, RST pin as output and CS pin as output
• Application Initialization - Initializes I2C driver and 3D Hall 3 to basic settings
• Application Task - Reads and logs XYZ axes values

void applicationTask( )
{
    c3dhall3_readXYZ( &axes_xyz[0] );

    mikrobus_logWrite( " X:", _LOG_TEXT );
    IntToStr( axes_xyz[0], text );
    mikrobus_logWrite( text, _LOG_TEXT );
    mikrobus_logWrite( " Y:", _LOG_TEXT );
    IntToStr( axes_xyz[1], text );
    mikrobus_logWrite( text, _LOG_TEXT );
    mikrobus_logWrite( " Z:", _LOG_TEXT );
    IntToStr( axes_xyz[2], text );
    mikrobus_logWrite( text, _LOG_LINE );
    
    Delay_ms(100);
}

The full application code, and ready to use projects can be found on our LibStock page.

Other mikroE Libraries used in the example:

• I2C
• SPI
• UART

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.
