Click library

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

Software Support

We provide a library for the Mcp16331Inv 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 Mcp16331Inv Click driver.

Standard key functions :

  • Config Object Initialization function.

    void mcp16331inv_cfg_setup ( mcp16331inv_cfg_t *cfg );

  • Initialization function.

    MCP16331INV_RETVAL mcp16331inv_init ( mcp16331inv_t ctx, mcp16331inv_cfg_t cfg );

  • Click Default Configuration function.

    void mcp16331inv_default_cfg ( mcp16331inv_t *ctx );

Example key functions :

  • 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.

  • 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 );

  • Generic SPI transfer, for sending and receiving packages

    void mcp16331inv_generic_transfer ( mcp16331inv_t ctx, spi_master_transfer_data_t block );

Examples Description

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

The demo application is composed of two sections :

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 );
}

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.Mcp16331Inv

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.

Flash 11 Click is a compact add-on board representing a highly reliable memory solution. This board features the AT25SF321B, a 32-Mbit SPI serial Flash memory with Dual I/O and Quad I/O support from Dialog Semiconductor. It is designed for applications in which the program code is shadowed from Flash memory into embedded or external RAM for execution and where small amounts of data are stored and updated locally in the Flash memory. It has a flexible and optimized erase architecture for code and data storage applications, non-volatile protection, three specialized protected programmable 256-byte OTP security registers, and a 64-bit factory programmable UID register.

IR distance Click

0

IR distance Click carries Sharp’s GP2Y0A60SZ0F distance measuring sensor, which comprises of an integrated PSD (position sensitive detector), an infrared LED and a signal processing circuit. The measuring range is between 10 and 150 cm. The Click is designed to run on either 3.3V or 5V power supply. It communicates with the target MCU over RST and AN pin on the mikroBUS™ line.
