Library Description

The library contains all the necessary functions for converting ADC values to real voltages and pressure values.

Key functions:

  • float pressure12_getPressure(uint16_t adcValue) - Convert ADC value to Pressure data in mBar.
  • float pressure12_getVoltage(uint16_t adcValue) - Convert ADC value to Voltage in mV.
  • void pressure12_setMaxVoltage(float volt) - Sets max output voltage on the AN pin.

Examples description

The application is composed of three sections :

  • System Initialization - Initializes LOG for logging data.
  • Application Initialization - ADC init.
  • Application Task - Reads ADC value, Convert ADC data to Voltage[mV] on the AN pin and convert to Pressure data in mBar. All data logs to the USBUART every 1sec.
	void applicationTask()
{
    uint16_t ADC_value;
    float Voltage;
    float Pressure;
    char demoText[ 50 ];

    ADC_value = pressure12_adcRead();
    Voltage = pressure12_getVoltage(ADC_Value);
    Pressure = pressure12_getPressure(ADC_Value);

    WordToStr(ADC_value, demoText);
    mikrobus_logWrite(" ADC value: ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_LINE);

    FloatToStr(Voltage, demoText);
    mikrobus_logWrite(" Voltage: ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_TEXT );
    mikrobus_logWrite(" mV", _LOG_LINE );

    FloatToStr(Pressure, demoText);
    mikrobus_logWrite(" Pressure: ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_TEXT);
    mikrobus_logWrite(" mBar", _LOG_LINE );

    mikrobus_logWrite("--------------------------", _LOG_LINE);
    Delay_ms( 1000 );
}

  • ADC Library
  • Conversion Library

Additional notes and informations

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

RTC 14 Click

0

RTC 14 Click is a compact add-on board that measures the passage of time. This board features the ISL1221, a low-power RTC with battery-backed SRAM and event detection from Renesas. The ISL1221 tracks time with separate registers for hours, minutes, and seconds, operating in normal and battery mode. It also can timestamp an event by either issuing an output signal, containing the second, minute, hour, date, month, and year that the triggering event occurred, or by stopping the RTC registers from advancing at the moment the event occurs. The calendar feature is exceptionally accurate through 2099, with automatic leap year correction.

Ambient 21 Click

0

Ambient 21 Click is a compact add-on board used to measure the amount of the present ambient light. This board features ams AG's TSL2591, a very-high sensitivity light-to-digital converter that transforms light intensity to a digital signal output capable of the direct I2C interface. It combines one broadband photodiode (visible plus infrared) and one infrared-responding photodiode on a single CMOS integrated circuit, providing a flexible and wide operating range of up to 88klx with an excellent responsivity close to the human eyes' response. The TSL2591 also has a programmable interrupt function and an integrated filter to reduce unwanted IR signals from the environment, improving lux accuracy across various light sources.
