Library Description

The library initializes and defines the I2C bus driver and drivers that offer a choice for writing data in register. The library includes function for read X/Y/Z axis data. The user also has the function for initializes chip and function for read interrupt state.

Key functions:

• int16_t accel7_getAxis(uint8_t _axis) - Functions for read axis data

• uint8_t accel7_init(uint8_t dataRes, uint8_t range) - Functions for initialize the chip

Examples description

The application is composed of the three sections :

• System Initialization - Initializes I2C module and set INT pin as INPUT
• Application Initialization - Initializes Driver init and settings accelerometer data range and data resolution which are necessary for the init chip.
• Application Task - (code snippet) - Reads the accel X / Y / Z axis data.

void applicationTask()
{
    X_axis = accel7_getAxis(_ACCEL7_AXIS_X);
    IntToStr(X_axis, demoText);
    mikrobus_logWrite("X axis:  ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_LINE);
    
    Y_axis = accel7_getAxis(_ACCEL7_AXIS_Y);
    IntToStr(Y_axis, demoText);
    mikrobus_logWrite("Y axis:  ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_LINE);

    Z_axis = accel7_getAxis(_ACCEL7_AXIS_Z);
    IntToStr(Z_axis, demoText);
    mikrobus_logWrite("Z axis:  ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_LINE);
    
    mikrobus_logWrite("  ", _LOG_LINE);
    Delay_ms( 1000 );
}

Other mikroE Libraries used in the example:

• SPI
• UART

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.
