Click library

  • Author : Stefan Ilic
  • Date : Aug 2023.
  • Type : I2C type

Software Support

We provide a library for the DIGI POT 14 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 POT 14 Click driver.

Standard key functions :

Example key functions :

  • digipot14_reg_write DIGI POT 14 register write function.
    err_t digipot14_reg_write ( digipot14_t *ctx, uint8_t reg, uint8_t data_in );
    err_t digipot14_reg_write(digipot14_t *ctx, uint8_t reg, uint8_t data_in)
    DIGI POT 14 register write function.
  • digipot14_set_pot_a_wiper DIGI POT 14 set the wiper position of potentiometer A function.
    err_t digipot14_set_pot_a_wiper ( digipot14_t *ctx, uint8_t wiper_pos );
    err_t digipot14_set_pot_a_wiper(digipot14_t *ctx, uint8_t wiper_pos)
    DIGI POT 14 set the wiper position of potentiometer A function.
  • digipot14_set_pot_b_wiper DIGI POT 14 set the wiper position of potentiometer B function.
    err_t digipot14_set_pot_b_wiper ( digipot14_t *ctx, uint8_t wiper_pos );
    err_t digipot14_set_pot_b_wiper(digipot14_t *ctx, uint8_t wiper_pos)
    DIGI POT 14 set the wiper position of potentiometer B function.

Example Description

This library contains API for DIGI POT 14 Click driver.

The demo application uses a digital potentiometer to change the resistance values.

The demo application is composed of two sections :

Application Init

The initialization of I2C module, log UART, and additional pins.

After the driver init, the app executes a default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
digipot14_cfg_t digipot14_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
digipot14_cfg_setup( &digipot14_cfg );
DIGIPOT14_MAP_MIKROBUS( digipot14_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == digipot14_init( &digipot14, &digipot14_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( DIGIPOT14_ERROR == digipot14_default_cfg ( &digipot14 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

This example demonstrates the use of the DIGI POT 14 Click boardâ„¢.

The demo application iterates through the entire wiper range. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
for ( uint8_t wiper_val = DIGIPOT14_MIN_POSITION; wiper_val <= DIGIPOT14_MAX_POSITION; wiper_val++ )
{
digipot14_set_pot_a_wiper( &digipot14, wiper_val );
digipot14_set_pot_b_wiper( &digipot14, wiper_val );
log_printf( &logger, " Resistance = %.3f KOhm \r\n",
Delay_ms( 1000 );
}
}

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.DIGIPOT14

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.
