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_res DIGI POT 14 set the resistance of potentiometer A function.
    err_t digipot14_set_pot_a_res ( digipot14_t *ctx, uint8_t resistance );
    err_t digipot14_set_pot_a_res(digipot14_t *ctx, uint8_t resistance)
    DIGI POT 14 set the resistance of potentiometer A function.
  • digipot14_set_pot_b_res DIGI POT 14 set the resistance of potentiometer B function.
    err_t digipot14_set_pot_b_res ( digipot14_t *ctx, uint8_t resistance );
    err_t digipot14_set_pot_b_res(digipot14_t *ctx, uint8_t resistance)
    DIGI POT 14 set the resistance 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 and sets the resistance in steps of approximately 10 kOhm. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
for ( uint8_t res_val = 0; res_val <= 100; res_val += 10 )
{
log_printf( &logger, " Resistance = %d KOhm \r\n", res_val );
digipot14_set_pot_b_res( &digipot14, res_val );
digipot14_set_pot_a_res( &digipot14, res_val );
Delay_ms( 5000 );
}
}
void application_task(void)
Definition: main.c:69

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.
