Software Support

We provide a library for the 3DHall2 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 driver and drivers that offer a choice for writing data in register and reads data from register. The library includes function for read hall X/Y/Z axis data, and temperature data.

Key functions :

• void c3dhall2_getAxisTempData(float *axisData, float *tempData) - Functions for gets Hall axis data and Temperature data
• void c3dhall2_configuration(uint8_t settings1, uint8_t settings2) - Functions for settings chip for measurement

Examples Description

The application is composed of three sections :

• System Initialization - Initializes I2C module
• Application Initialization - Initialization driver init and configuration chip
• Application Task - (code snippet) - Reads X/Y/Z hall axis and Temperature data. All data logs on the USBUART every 3 sec.

void applicationTask()
{
    c3dhall2_getAxisTempData(&XYZ_Axis[0], &Temperature);

    mikrobus_logWrite("Axis X: ", _LOG_TEXT);
    FloatToStr(XYZ_Axis[0],demoText);
    mikrobus_logWrite(demoText, _LOG_TEXT);
    mikrobus_logWrite(" mT", _LOG_LINE);
   
    mikrobus_logWrite("Axis Y: ", _LOG_TEXT);
    FloatToStr(XYZ_Axis[1],demoText);
    mikrobus_logWrite(demoText, _LOG_TEXT);
    mikrobus_logWrite(" mT", _LOG_LINE);
   
    mikrobus_logWrite("Axis Z: ", _LOG_TEXT);
    FloatToStr(XYZ_Axis[2],demoText);
    mikrobus_logWrite(demoText, _LOG_TEXT);
    mikrobus_logWrite(" mT", _LOG_LINE);
   
    mikrobus_logWrite("Temperature :", _LOG_TEXT);
    FloatToStr(Temperature,demoText);
    mikrobus_logWrite(demoText, _LOG_TEXT);
    mikrobus_logWrite(" C", _LOG_LINE);
   
    mikrobus_logWrite(" ", _LOG_LINE);
    Delay_ms(3000);
}

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

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.
