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, read sensor time and detect tap on the chip and function for read temperature data.
The user also has the function for initializes chip and software reset.

Key functions:

• int16_t accel5_getAxis(uint8_t axis) - Functions for read axis data
• uint8_t accel5_init(uint8_t mode, uint8_t range) - Functions for initialize the chip
• void accel5_writeByte(uint8_t reg, uint8_t _data) - Functions for write one byte in register

Example description

The application is composed of three sections :

System Initialization - Initializes I2C module
Application Initialization - Initializes Driver init and settings accelerometer data range and mode
Application Task - (code snippet) - Reads the accel X / Y / Z axis data, every 500 ms.

void applicationTask()
{
 X_axisData = accel5_getAxis( _ACCEL5_X_AXIS );
 mikrobus_logWrite(" X axis : ", _LOG_TEXT );
 IntToStr(X_axisData, demoText);
 mikrobus_logWrite(demoText, _LOG_LINE );

 Y_axisData = accel5_getAxis( _ACCEL5_Y_AXIS );
 mikrobus_logWrite(" Y axis : ", _LOG_TEXT );
 IntToStr(Y_axisData, demoText);
 mikrobus_logWrite(demoText, _LOG_LINE );

 Z_axisData = accel5_getAxis( _ACCEL5_Z_AXIS );
 mikrobus_logWrite(" Z axis : ", _LOG_TEXT );
 IntToStr(Z_axisData, demoText);
 mikrobus_logWrite(demoText, _LOG_LINE );

 mikrobus_logWrite( " ", _LOG_LINE );
 Delay_ms( 500 );
}

Other MikroElektronika 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.
