Library Description

Initializes and defines I2C driver, defines driver's function which writes data in registers, reads data from registers, reads and converts temperature to Celsius value with determined resolution, and checks Alert pin for temperature limit.

Key functions

Function writes 8-bit or 16-bit data in register- Function writes 8-bit or 16-bit data in register

uint16_t temp_log_readReg(uint8_t register_address);- Function reads 16-bit data from register

uint16_t temp_log_readTempDec(uint16_t resolution);- Function reads 16-bit temperature data from register with determined resolution

float temp_log_convertToCelsius(uint16_t temperature_data);- Function converts 16-bit temperature data to Celsius value

uint8_t temp_log_getAlert();- Function checks state of Alert pin (ALT)

Example description

  • System Initialization - Initializes peripherals and pins.
  • Application Initialization - Initializes click driver.
  • Application Task - Reads temperature from the temperature register in decimal value in 9-bit resolution, converts that decimal value in Celsius value and checks Alert pin which becomes active (low) if the measured temperature meets or exceeds the high temperature limit.
void applicationTask()
{
    uint16_t temperature = 0;
    float temp = 0;
    uint16_t temp_limit = 0;
    char txt[4] = {0};
    char txt1[10] = {0};

    temperature = temp_log_readTempDec(_TEMP_LOG_RESOLUTION_9_BITS);
    temp = temp_log_convertToCelsius(temperature);

    IntToStr(temperature, txt);
    mikrobus_logWrite("Temperature in decimal value is: ", _LOG_TEXT);
    mikrobus_logWrite(txt, _LOG_LINE);

    FloatToStr(temp, txt1);
    mikrobus_logWrite("Temperature in celsius value is: ", _LOG_TEXT);
    mikrobus_logWrite(txt1, _LOG_LINE);

    if(temp_log_getAlert() == 0)
    {
        mikrobus_logWrite("TEMPERATURE LIMIT ALARMING!", _LOG_LINE);
    }

    Delay_ms(1000);
}

Additional notes and information

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.

Environment 3 Click

0

Environment 3 Click is a compact add-on board that contains a four-in-one environmental measurement solution. This board features BME688, a first gas sensor with Artificial Intelligence (AI), and integrated high-linearity/high-accuracy pressure, humidity, and temperature sensors from Bosch Sensortech. The BME688 can detect Volatile Organic Compounds (VOCs), Volatile Sulfur Compounds (VSCs), and other gases such as carbon monoxide and hydrogen in part per billion (ppb) range. It provides absolute temperature accuracy, typical of ±1°C, and best performance when operated within the pressure, temperature, and humidity range of 300-110hPa, 0-65°C, and 10-90%RH.

SwipeSwitch Click is capacitive touch, gesture, and proximity sensing Click board™, which is equipped with the IQS266, an integrated trackpad controller circuit which features ProxSense® and IQ Switch® technologies. This IC consists of a 2x3-channel capacitive trackpad controller, and a single self-capacitive proximity sensor, which can be used to wake up the device. This ensures very low power consumption, as the device is able to stay in the Sleep mode when not used. The IQS266 can detect a number of various configurable swipe and tap gestures. An Automatic Tuning Implementation (ATI) feature ensures an optimized performance in various conditions.
