Click library

  • Author : Nenad Filipovic
  • Date : Aug 2023.
  • Type : SPI type

Software Support

We provide a library for the ADC 14 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 ADC 14 Click driver.

Standard key functions :

  • adc14_cfg_setup Config Object Initialization function.

    void adc14_cfg_setup ( adc14_cfg_t *cfg );
  • adc14_init Initialization function.

    err_t adc14_init ( adc14_t *ctx, adc14_cfg_t *cfg );

Example key functions :

  • adc14_get_voltage ADC 14 get voltage function.

    err_t adc14_get_voltage ( adc14_t *ctx, float *voltage );
  • adc14_read_conversion_data ADC 14 read conversion data function.

    err_t adc14_read_conversion_data ( adc14_t *ctx, uint16_t *adc_data );
  • adc14_set_vref ADC 14 set voltage reference function.

    err_t adc14_set_vref ( adc14_t *ctx, float vref );

Example Description

This example demonstrates the use of the ADC 14 Click board™ by reading results of AD conversion by using SPI serial interface.

The demo application is composed of two sections :

Application Init

Initialization of SPI module and log UART and enabled internal voltage reference.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    adc14_cfg_t adc14_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.
    adc14_cfg_setup( &adc14_cfg );
    ADC14_MAP_MIKROBUS( adc14_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == adc14_init( &adc14, &adc14_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
    Delay_ms ( 100 );
}

Application Task

The demo application gets the voltage levels from analog input and displays the results. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
    float voltage = 0.0;
    if ( ADC14_OK == adc14_get_voltage( &adc14, &voltage ) )
    {
        log_printf( &logger, " Voltage : %.2f [mV]\r\n", 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.ADC14

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.

SRAM click

6

SRAM click lets you add 1 Mbit of additional SRAM memory to your devices, via the 23LC1024 chip. The board communicates with the target MCU through the mikroBUS SPI interface (MISO, MOSI, SCK, CS). SRAM click is designed to use either a 3.3V or 5V power supply.

I2C to CAN Click

0

I2C to CAN Click is a compact add-on board that contains I2C to CAN-physical transceiver, which extends a single-master I2C bus through harsh or noisy environments. This board features the LT3960, a robust high-speed transceiver that extends a single-master I2C bus up to 400kbps using the CAN-physical layer from Analog Devices. One LT3960 from SCL and SDA I2C lines creates equivalent differential buses (CAN) on two twisted pairs, while the second LT3960 recreates the I2C bus locally for any slave I2C devices on the other end of the twisted pairs. A built-in 3.3V LDO powers both the I2C and CAN lines from a single input supply from 4V to 60V. This Click board™ is suitable for industrial and automotive networking, remote sensor applications, and more.

Hall Current 12 Click

0

Hall Current 12 Click is a compact add-on board that provides economical and precise AC or DC current sensing solutions. This board features the TMCS1100, a galvanically isolated Hall-effect current sensor capable of DC or AC current measurement with high accuracy, excellent linearity, and temperature stability from Texas Instruments. It enables the lowest drift, <1% full-scale error, and highest accuracy over time and temperature. It also provides a reliable 600V lifetime working voltage and 3kVRMS isolation between the current path and circuitry with uni/bidirectional current sensing. Besides, the user is allowed to process the output signal in analog or digital form.
