GainAMP Click

GainAMP Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

This is an example that demonstrates the use of the GainAMP Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.GainAMP

Example Key Functions

• gainamp_cfg_setup Config Object Initialization function.

void gainamp_cfg_setup ( gainamp_cfg_t *cfg );

• gainamp_init Initialization function.

err_t gainamp_init ( gainamp_t *ctx, gainamp_cfg_t *cfg );

• gainamp_default_cfg Click Default Configuration function.

err_t gainamp_default_cfg ( gainamp_t *ctx );

• gainamp_read_an_pin_value GainAMP read AN pin value function.

err_t gainamp_read_an_pin_value ( gainamp_t *ctx, uint16_t *data_out );

• gainamp_read_an_pin_voltage GainAMP read AN pin voltage level function.

err_t gainamp_read_an_pin_voltage ( gainamp_t *ctx, float *data_out );

• gainamp_set_gain Function for sets gain of the GainAMP Click.

void gainamp_set_gain ( gainamp_t *ctx, uint8_t gain );

Application Init

Initializes SPI module and set CS pin and RST pin as OUTPUT, initialization driver init and resets chip.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    gainamp_cfg_t gainamp_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.

    gainamp_cfg_setup( &gainamp_cfg );
    GAINAMP_MAP_MIKROBUS( gainamp_cfg, MIKROBUS_1 );
    err_t init_flag  = gainamp_init( &gainamp, &gainamp_cfg );
    if ( ( SPI_MASTER_ERROR == init_flag ) || ( ADC_ERROR == init_flag ) ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

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

Application Task

Sets the gain for both channels, channel A and channel B.

void application_task ( void )
{
    gainamp_set_gain( &gainamp, GAINAMP_CHANNEL_A_x1 | GAINAMP_CHANNEL_B_x5 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    
    gainamp_set_gain( &gainamp, GAINAMP_CHANNEL_A_x10 | GAINAMP_CHANNEL_B_x100 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
