MCP16331 INV Click

MCP16331 INV 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.

Click Library

• Author : MikroE Team
• Date : jan 2020.
• Type : SPI type

Software Support

Example Description

This application enables usage of this Click as a buck-boost voltage regulator.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Mcp16331Inv

Example Key Functions

• mcp16331inv_cfg_setup Config Object Initialization function.

void mcp16331inv_cfg_setup ( mcp16331inv_cfg_t *cfg );

• mcp16331inv_init Initialization function.

err_t mcp16331inv_init ( mcp16331inv_t *ctx, mcp16331inv_cfg_t *cfg );

• mcp16331inv_default_cfg Click Default Configuration function.

void mcp16331inv_default_cfg ( mcp16331inv_t *ctx );

• mcp16331inv_enable_vin Function enables or disables internal VIN pull up.

void mcp16331inv_enable_vin ( mcp16331inv_t *ctx, uint8_t state );

• Function determines DAC output voltage value in depending on the input DAC_value (0x0000 - 0x0FFF) and gain_value.
• mcp16331inv_set_dac_vout Function also can put device on active or shutdown mode.

void mcp16331inv_set_dac_vout ( mcp16331inv_t *ctx, uint16_t dac_value, uint8_t gain_value, uint8_t mode );

• mcp16331inv_generic_transfer Generic SPI transfer, for sending and receiving packages.

void mcp16331inv_generic_transfer ( mcp16331inv_t *ctx, spi_master_transfer_data_t *block );

Application Init

Initializes Click driver and enables VIN Pull Up.

void application_init ( void )
{
    log_cfg_t log_cfg;
    mcp16331inv_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.

    mcp16331inv_cfg_setup( &cfg );
    MCP16331INV_MAP_MIKROBUS( cfg, MIKROBUS_1 );

    Delay_ms ( 100 );

    mcp16331inv_init( &mcp16331inv, &cfg );

    Delay_ms ( 100 );

    mcp16331inv_enable_vin( &mcp16331inv, MCP16331INV_ENABLE_VIN_PULL_UP );
}

Application Task

Sets DAC output voltage on 3500mV, when gain is set up on 1x VREF, on 4s delay time, and then sets DAC output voltage on 5000mV, when gain is now set up on 2x VREF, on also 4s delay time. VIN Pull Up voltage must be greater than 4V.

void application_task ( void )
{
    //  Task implementation.

    mcp16331inv_set_dac_vout( &mcp16331inv, MCP16331INV_3500_MV_1X_GAIN, MCP16331INV_GAIN_1X_VREF, MCP16331INV_ACTIVE_MODE );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    mcp16331inv_set_dac_vout( &mcp16331inv, MCP16331INV_5000_MV_2X_GAIN, MCP16331INV_GAIN_2X_VREF, MCP16331INV_ACTIVE_MODE );
    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.
