The Compass 6 Click Board™ is a compact add-on board perfect for implementation in applications such as an electronic compass. This board features the HSCDTD008A, a high-sensitivity geomagnetic sensor from ALPS Alpine. This I2C configurable compass incorporates a magnetic sensor capable of measuring magnetic field strengths of ±2.4mT on each of its three axes and provides an output resolution of 0.15µT/LSB. The more comprehensive measurement range of the HSCDTD008A is the result of applying a thin-film process and magnetic simulation technology. This Click Board™ is intended for use in compact electronic equipment and works well in robotic applications because of its terrestrial magnetism detection function.
The Compass 6 Click Board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click Board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
How Does The Compass 6 Click Board™ Work?
The Compass 6 Click Board™ as its foundation uses the HSCDTD008A, a high-sensitivity three-axis terrestrial magnetism sensor from ALPS Alpine. It comes with an integrated drive circuit, signal processing circuit, and serial interface block, allowing low noise and high resolution. The HSCDTD008A can measure magnetic field strengths of ±2.4mT on each of its three axes and provides an output resolution of 0.15µT/LSB. This Click board™ represents a perfect choice for implementation in applications such as an electronic compass.
At the beginning of the operation, all internal circuits and registers are set to the default state by turning the power ON. The operating mode is set to a low-power Standby mode automatically by Power-On reset. In addition to the Standby mode, this sensor also has an Active mode for power control accessible through a register command. The active mode has two states: the force state that starts measurement and outputs data by register command, and the Normal state, which performs measurement and outputs data using the internal timer trigger.
Compass 6 Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Standard Mode operation with a clock frequency of 100kHz, Fast Mode up to 400kHz, and Fast Mode Plus up to 1MHz, in addition to the High-Speed Mode. It also features an additional ready signal, labeled as RDY and routed on the INT pin of the mikroBUS™ socket, that informs when new measured results for the host are updated.
This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.

Key Functions
compass6_cfg_setup- Config Object Initialization function.compass6_init- Initialization function.compass6_default_cfg- Click Default Configuration function.
Example Description
This example is a showcase the ability of the device to read 3 axis data of magnetic raw value when data is ready.
void application_task ( void )
{
if ( compass6_data_ready( &compass6 ) )
{
compass6_axes_t axes_data;
compass6_get_axes_data( &compass6, &axes_data );
log_printf( &logger, " > X: %drn", axes_data.x );
log_printf( &logger, " > Y: %drn", axes_data.y );
log_printf( &logger, " > Z: %drn", axes_data.z );
log_printf( &logger, "*********************rn" );
Delay_ms( 500 );
}
}
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:

Additional Notes and Information
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.
mikroSDK
This Click board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
