Library Description

The library covers all the necessary functions to control CO Click board. CO click communicates with the target board via analog ( AN ) pin. This library contains drivers for read ADC value of MQ-7 sensor.

Key functions:

  • float co_voltageConversion( uint32_t adcValue, float vRef ) - Convert the voltage function.
  • float co_getRatio( uint32_t adcValue, float vRef ) - Get the sensor ratio function.
  • float co_getSensorResistance( uint32_t adcValue, float vRef ) - Get the sensor resistance.

Examples description

The application is composed of the three sections :

  • System Initialization - Initializes GPIO and LOG structures, sets AN pin as input.
  • Application Initialization - Initialization driver enables GPIO and ADC, also starts write log.
  • Application Task - (code snippet) This is a example which demonstrates the use of CO Click board. CO Click reads ADC value. Results are being sent to the Usart Terminal where you can track their changes. All data logs on usb uart changes for every 1 sec.
void applicationTask()
{      
    valueADC = co_readADC(); 
    Delay_100ms(); 
    
    IntToStr( valueADC, logText );
    mikrobus_logWrite( " ADC value: ", _LOG_TEXT );
    mikrobus_logWrite( logText, _LOG_LINE );
    mikrobus_logWrite( "-------------------", _LOG_LINE );
    Delay_1sec();
}


Additional Functions :

  • void co_adcInit() - Function ADC initialization.
  • uint32_t co_readADC() - Function read ADC value.

Other mikroE Libraries used in the example:

  • ADC
  • UART
  • Conversions

Additional notes and information

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.

TempHum 24 Click

0

Temp&Hum 24 Click is a compact add-on board that measures the surrounding environment's humidity and temperature. This board features the HDC3021, an integrated capacitive-based relative humidity and temperature sensor with a removable tape cover from Texas Instruments. The HDC3021 is characterized by its high accuracy (±0.5%RH and ±0.1°C over a wide operating temperature range) and high resolution, providing 16-bit data to the host controller with a configurable I2C interface. Offset Error Correction reduces RH sensor offset due to aging, exposure to extreme operating conditions, and contaminants to return the device to within accuracy specifications.
