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 form register. The library includes function for read Pressure data in mBar/hPa/kPa/Torr or mmHg. The user also has the function for set PSI Range, function for reset device, function for get read Satatus and function for read interrupt state.

Key functions:

  • float pressure8_getPressure(uint8_t pressureIn) - Functions for get Pressure data.
  • void pressure8_reset() - Functions for reset device.
  • void pressure8_setPSIRange(float PSI_min, float PSI_max) - Functions for set PSI range.

Examples description

The application is composed of the three sections :

  • System Initialization - Initializes I2C module and sets INT pin as INPUT and RST pin as OUTPUT.
  • Application Initialization - Initialization driver init, reset device and set PSI range.
  • Application Task - (code snippet) - Reads Pressure data and this data logs to USBUART every 1 sec.
void applicationTask()
{
    float PressureData;
    char demoText[ 50 ];
    
    PressureData = pressure8_getPressure(_PRESSURE8_DATA_IN_mBar);
    FloatToStr(pressureData, demoText);
    mikrobus_logWrite(" Pressure data : ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_TEXT);
    mikrobus_logWrite(" mBar", _LOG_LINE);
    Delay_ms( 1000 );
}

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB UART 2 clickor 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.

Expand 3 Click

0

Expand 3 Click is a compact add-on board providing general-purpose I/O expansion. This board features the DS2408, an 8-channel programmable I/O expander from Analog Devices. The DS2408 has a factory-lasered 64-bit registration number, enabling multiple Expand 3 Click boards™ to be connected on the same data line, communicating with the host MCU through a standard Dallas Semiconductor 1-Wire interface (15.3kbps or 100kbps). PIO outputs are configured as open-drain and provide a maximum on-resistance of 100Ω.
