DIGI POT 3 click

DIGI POT 3 click is a versatile and feature-rich digital potentiometer click with 1024 steps and an internal non-volatile memory (EEMEM), which can be used for storing the wiper position, but also for storing various user data.

Click library

Software Support

We provide a library for the DigiPot3 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 DigiPot3 Click driver.

Standard key functions :

Example key functions :

Examples Description

This app get value from digital potentiometer and stored to the EEMEM memory.

The demo application is composed of two sections :

Application Init

Initializes device.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----\r\n" );
// Click initialization.
DIGIPOT3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
digipot3_init( &digipot3, &cfg );
Delay_ms( 200 );
{
}
log_printf( &logger, "DIGI POT 3 is initialized \r\n" );
Delay_ms( 200 );
}

Application Task

Increments the wiper position by 6dB every 2 seconds. When wiper position reaches the desired value (0x0200), then the wiper position be decremented by 6dB every 2 seconds, until position value reaches the new desired value (0x0002). After that the new position value will be stored to the EEMEM memory, if that value does not already exist in the EEMEM memory.

void application_task ( void )
{
while ( digital_value < 0x0200 )
{
log_printf( &logger, "DAC value is: %u \r\n", digital_value );
Delay_ms( 2000 );
}
while ( digital_value > 0x0002 )
{
log_printf( &logger, "DAC value is: %u \r\n", digital_value );
Delay_ms( 2000 );
}
{
}
}

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.

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.
