Click library

  • Author : Jelena Milosavljevic
  • Date : Jun 2021.
  • Type : ADC type

Software Support

We provide a library for the LPG Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for LPG Click driver.

Standard key functions :

  • lpg_cfg_setup Config Object Initialization function.

    void lpg_cfg_setup ( lpg_cfg_t *cfg );
  • lpg_init Initialization function.

    LPG_RETVAL lpg_init ( lpg_t *ctx, lpg_cfg_t *cfg );

Example key functions :

  • lpg_read_an_pin_value This function reads results of AD conversion of the AN pin.

    err_t lpg_read_an_pin_value ( lpg_t *ctx, uint16_t *data_out );
  • lpg_read_an_pin_voltage This function reads results of AD conversion of the AN pin and converts them to proportional voltage level.

    err_t lpg_read_an_pin_voltage ( lpg_t *ctx, float *data_out );

Example Description

The demo application shows the reading of the adc values given by the sensors.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects.


void application_init ( void ) {
    log_cfg_t log_cfg;  /**< Logger config object. */
    lpg_cfg_t lpg_cfg;  /**< Click config object. */

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.

    lpg_cfg_setup( &lpg_cfg );
    LPG_MAP_MIKROBUS( lpg_cfg, MIKROBUS_1 );
    if ( lpg_init( &lpg, &lpg_cfg ) == ADC_ERROR ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }
    log_info( &logger, " Application Task " );
}

Application Task

Reads the adc value and prints in two forms (DEC and HEX).


void application_task ( void ) {
    uint16_t lpg_an_value = 0;

    if ( lpg_read_an_pin_value ( &lpg, &lpg_an_value ) != ADC_ERROR ) {
        log_printf( &logger, " ADC Value : %u\r\n", lpg_an_value );
    }

    float lpg_an_voltage = 0;

    if ( lpg_read_an_pin_voltage ( &lpg, &lpg_an_voltage ) != ADC_ERROR ) {
        log_printf( &logger, " AN Voltage : %.3f[V]\r\n\n", lpg_an_voltage );
    }

    Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.LPG

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.

BT Audio 3 Click

0

BT Audio 3 Click is a compact add-on board with high-performing voice and audio post-processing capability for Bluetooth audio applications. This board features the BM83, a fully certified Bluetooth v5.0 stereo audio module from Microchip. The BM83 contains an onboard Bluetooth stack and audio profiles and supports 24-bit/96 kHz high-resolution audio formats to enable high-fidelity wireless audio. An integrated Digital Signal Processor (DSP) decodes AAC and SBC codecs and executes advanced audio and voice processing such as Wide-Band (WB) speech, Acoustic Echo Cancellation (AEC), and Noise Reduction (NR). Configured in Host mode, the BM83 allows data processing via the UART interface, and in addition, comes with many additional features such as audio control buttons, onboard microphones, LED indicators, and more.

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.
