DIGI POT click

DIGI POT Click is an accessory board in mikroBUS form factor.


Click library

Software Support

We provide a library for the DigiPot 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 DigiPot Click driver.

Standard key functions :

Example key functions :

Examples Description

The demo application changes the resistance using DIGIPOT Click.

The demo application is composed of two sections :

Application Init

Initializes SPI and LOG modules.

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 ----" );
// Click initialization.
DIGIPOT_MAP_MIKROBUS( cfg, MIKROBUS_1 );
digipot_init( &digipot, &cfg );
log_printf( &logger, " DIGI POT Click\r\n" );
log_printf( &logger, "------------------------\r\n" );
}

Application Task

This is an example which demonstrates the use of DIGI POT Click board. Increments the wiper position by 10 positions every 5 seconds.

void application_task ( void )
{
// Task implementation.
for ( n_cnt = 127; n_cnt < 255; n_cnt += 10 )
{
wiper_pos = ( uint8_t ) n_cnt;
Delay_ms( 5000 );
}
}

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.
