Library Description

The library provides generic functions for working with the click board.

Key functions:

• uint8_t gyro2_getId() - Function for reading the ID register of the click board.

• void gyro2_getAxisraw(int16_t *axisData) - Function for reading the raw axis data from the click board.

• void gyro2_calcAxis(int16_t *axisData) - Function for calculating the axis data.

Examples description

The application is composed of the three sections :

• System Initialization - Initialize the GPIO and communication structures.
• Application Initialization - Initialize the communication interface and configure the click board.
• Application Task - Read the x,y,z and temperature data from the click board and display the resoults on the serial port.

void applicationTask()
{
    char text[10];
    int16_t axisData[3];
    char state;
    char temperature;

    gyro2_getAxisraw(&axisData[0]);
    gyro2_calcAxis(&axisData[0]);

    IntToStr(axisData[0],&text[0]);
    Ltrim(&text[0]);
    mikrobus_logWrite("x: ",_LOG_TEXT);
    mikrobus_logWrite(&text[0],_LOG_LINE);
    IntToStr(axisData[1],&text[0]);
    Ltrim(&text[0]);
    mikrobus_logWrite("y: ",_LOG_TEXT);
    mikrobus_logWrite(&text[0],_LOG_LINE);
    IntToStr(axisData[2],&text[0]);
    Ltrim(&text[0]);
    mikrobus_logWrite("z: ",_LOG_TEXT);
    mikrobus_logWrite(&text[0],_LOG_LINE);
    temperature=gyro2_readTemperature();
    ByteToStr(temperature,&text[0]);
    Ltrim(&text[0]);
    mikrobus_logWrite("Temperature: ",_LOG_TEXT);
    mikrobus_logWrite(&text[0],_LOG_TEXT);
    mikrobus_logWrite(" °C",_LOG_LINE);
    mikrobus_logWrite("++",_LOG_LINE);
    Delay_ms(200);

}

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.
