Compass 4 Click is a compact add-on board that can measure the three-axis magnetic field that is perfect for implementation in applications such as electric compasses.
We provide a library for the Compass4 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.
This library contains API for Compass4 Click driver.
void compass4_cfg_setup ( compass4_cfg_t *cfg );
COMPASS4_RETVAL compass4_init ( compass4_t *ctx, compass4_cfg_t *cfg );
uint8_t compass4_get_interrupt ( compass4_t *ctx );
uint8_t compass4_get_single_axis ( compass4_t *ctx, uint8_t axis_reg, int16_t *axis_data );
uint8_t compass4_get_magnetic_flux ( compass4_t *ctx, compass4_flux_t *flux );
This demo application measures magnetic flux data.
The demo application is composed of two sections :
Initializes the driver and resets the module, then checks the communication with the module and sets the module default configuration.
Reads magnetic flux data and displays the values of X, Y, and Z axis to the USB UART each second.
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.

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.
