Pac1934 Click

Pac1934 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.

Software Support

Example Description

This application measures the voltage.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Pac1934

Example Key Functions

• pac1934_cfg_setup Config Object Initialization function.

void pac1934_cfg_setup ( pac1934_cfg_t *cfg );

• pac1934_init Initialization function.

err_t pac1934_init ( pac1934_t *ctx, pac1934_cfg_t *cfg );

• pac1934_write_byte Write one byte function.

void pac1934_write_byte ( pac1934_t *ctx, uint8_t wr_addr, uint8_t wr_data );

• pac1934_read_byte Read one byte function.

uint8_t pac1934_read_byte ( pac1934_t *ctx, uint8_t rd_addr );

• pac1934_send_command Send command function.

void pac1934_send_command ( pac1934_t *ctx, uint8_t wr_cmd );

Application Init

Initalizes device, enables the device and makes an initial log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    pac1934_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.

    pac1934_cfg_setup( &cfg );
    PAC1934_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    pac1934_init( &pac1934, &cfg );
}

Application Task

This is an example that shows the most important functions that PAC1934 Click has, it mesures voltage, current, power and energy.

void application_task ( void )
{
    float read_value;
    
    pac1934_dev_reset( &pac1934 );
    pac1934_write_byte( &pac1934, PAC1934_CHANNEL_DIS, PAC1934_CHANNEL_DIS_ALL_CHA );
    pac1934_write_byte( &pac1934, PAC1934_CTRL_REG, PAC1934_CTRL_SAMPLE_RATE_8 | PAC1934_CTRL_SINGLE_SHOT_MODE );
    Delay_ms ( 100 );
    pac1934_send_command( &pac1934, PAC1934_REFRESH_CMD );
    
    read_value = pac1934_measure_voltage( &pac1934, 1 );
    log_printf( &logger, "Voltage : %.2f V\r\n", read_value );

    read_value = pac1934_measure_current( &pac1934, 1 );
    log_printf( &logger, "Amperage :  %.2f mA\r\n", read_value );

    read_value = pac1934_measure_power( &pac1934, 1 );
    log_printf( &logger, "Power : %.2f W\r\n", read_value );
    
    read_value = pac1934_measure_energy( &pac1934, 1, 8 );
    log_printf( &logger, "Energy :  %.2f J \r\n", read_value );
    log_printf( &logger, "--------------------- \r\n" );
    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.
