Library Description

The library contains a function which, based on the ADC value, detects which button is pressed.

Key functions:

  • uint8_t analogkey_getKey(uint16_t adcValue) - Detects which button is pressed.

Examples description

The application is composed of the three sections :

  • System Initialization - LOG initialization for displaying data on USB UART.
  • Application Initialization - Initializes ADC init.
  • Application Task - (code snippet) - Reads ADC value and detects which button is pressed based on that value.
void applicationTask()
{
    uint16_t ADC_value;
    uint8_t isKey;
    char demoText[ 50 ];
    uint8_t cnt;
    uint16_t sumValue = 0;
    
    for(cnt = 0; cnt < 5; cnt++)
    {
        ADC_value = analogkey_adcRead();
        sumValue += ADC_value;
        Delay_10ms();
    }
    ADC_value = sumValue / 5;
    isKey = analogkey_getKey(ADC_value);
    
    if(isKey != _ANALOGKEY_NO_TOUCH)
    {
        IntToStr(isKey, demoText);
        mikrobus_logWrite("Pressed the button : ", _LOG_TEXT);
        mikrobus_logWrite(demoText, _LOG_LINE);
    }
    Delay_ms( 300 );
}

Other mikroE Libraries used in the example:

  • ADC
  • UART

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.

ADC 20 Click

0

ADC 20 Click is a compact add-on board with a high-performance data converter. This board features the TLA2518, an SPI-configurable eight-channel 12-bit successive approximation register analog-to-digital converter (SAR ADC) from Texas Instruments. The TLA2518 has an internal oscillator for the ADC conversion and supports averaging multiple data samples with a single conversion start. Also, the built-in programmable averaging filters help reduce noise from the analog inputs and reduce the number of data samples required to be read by the host MCU. All eight channels can be used as analog inputs, with the addition that the four channels can be used as digital inputs or digital outputs.

GPS Parser

8

For those wishing to have all the information possible from their GPS, there's a click for that. This library is a gps parser. What is does is separates the various sentences that come from the gps satellites into useful parts and pieces. Then gives the developer access the the underlying data with useful getter type functions.
