Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : SPI type

Software Support

We provide a library for the current2 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for current2 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void current2_cfg_setup ( current2_cfg_t *cfg );

  • Initialization function.

    CURRENT2_RETVAL current2_init ( current2_t ctx, current2_cfg_t cfg );

Example key functions :

  • Get ADC function

    uint16_t current2_get_adc ( current2_t *ctx );

  • Get Averaged ADC function

    uint16_t current2_get_average_adc ( current2_t *ctx, uint8_t n_samp );

  • Get Current function

    uint16_t current2_get_current ( current2_t *ctx, uint8_t n_sample );

Examples Description

This application measures current.

The demo application is composed of two sections :

Application Init

Initializes SPI interface in Mode 0


void application_init ( void )
{
    log_cfg_t log_cfg;
    current2_cfg_t cfg;

    /** 
     * 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.

    current2_cfg_setup( &cfg );
    CURRENT2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    current2_init( &current, &cfg );
    Delay_ms ( 300 );
    log_printf( &logger, "Current 2 is initialized \r\n \r\n" );
}

Application Task

Reads the current averaged result of 20 samples and gets this result in a proper value [mA]. Repeats the current reading every 500ms.


void application_task ( void )
{
    uint16_t tmp;

    tmp = current2_get_current( &current, 20 );

    log_printf( &logger, "Current : %d mA \r\n", tmp );

    Delay_ms ( 500 );
} 

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Current2

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.

RMS to DC 2 Click

0

RMS to DC 2 Click is a compact add-on board that converts the RMS of the input signal into a DC voltage. This board features the AD8436, a low-cost, low-power, true RMS-to-DC converter from Analog Devices. The AD8436 is a translinear precision, low-power, true RMS-to-DC converter that delivers true RMS or average rectified value of AC waveform. It features high accuracy, a wide dynamic input range (100μV rms to 3V rms), a wide bandwidth of up to 1MHz, and more. This Click board™ makes the perfect solution for the development of various true RMS digital multimeter applications, panel meters and gauges, AC + DC measurement applications, a true RMS measurement of an audio signal, and other similar applications that require accurate RMS value readings.

Expand 11 Click

0

Expand 11 Click is a compact add-on board that contains a multi-port I/O expander. This board features the TCA9536, a general-purpose remote I/O expansion for most microcontroller families from Texas Instruments. The TCA9536 comes in a 4-port configuration and allows easy addition of I/O through a standard I2C serial interface. Each port is user-configurable to either a logic input or logic output by writing to the I/O configuration register bits. The data for each input or output is kept in the corresponding input or output register. There is an additional special function register that port P3, in addition to its standard I/O function, can also configure as an interrupt feature.
