Click library

  • Author : Stefan Ilic
  • Date : Dec 2023.
  • Type : SPI type

Software Support

We provide a library for the DIGI IN 2 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for DIGI IN 2 Click driver.

Standard key functions :

Example key functions :

  • digiin2_get_flt_pin This function is used to get state of the FLT pin.
    uint8_t digiin2_get_flt_pin ( digiin2_t *ctx );
    uint8_t digiin2_get_flt_pin(digiin2_t *ctx)
    DIGI IN 2 get FLT pin state function.
  • digiin2_write_reg This function is used to write data into the selected register by using SPI serial interface.
    err_t digiin2_write_reg ( digiin2_t *ctx, uint8_t reg, uint8_t data_in );
    err_t digiin2_write_reg(digiin2_t *ctx, uint8_t reg, uint8_t data_in)
    DIGI IN 2 register write function.
  • digiin2_read_reg This function reads a data byte from the selected register by using SPI serial interface.
    err_t digiin2_read_reg ( digiin2_t *ctx, uint8_t reg, uint8_t *data_out );
    err_t digiin2_read_reg(digiin2_t *ctx, uint8_t reg, uint8_t *data_out)
    DIGI IN 2 register reading function.

Example Description

This example demonstrates the use of DIGI IN 2 Click board by reading and displaying the state of the channels.

The demo application is composed of two sections :

Application Init

Initializes the driver, performs the click default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
digiin2_cfg_t digiin2_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
digiin2_cfg_setup( &digiin2_cfg );
DIGIIN2_MAP_MIKROBUS( digiin2_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == digiin2_init( &digiin2, &digiin2_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( DIGIIN2_ERROR == digiin2_default_cfg ( &digiin2 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Reads and displays on the USB UART the channel state every second.

void application_task ( void )
{
uint8_t channel_data = 0;
digiin2_pulse_latch( &digiin2 );
if ( DIGIIN2_OK == digiin2_read_reg( &digiin2, DIGIIN2_REG_DISTATE, &channel_data ) )
{

}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.DIGIIN2

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. UART terminal is available in all MikroElektronika compilers.
