DIGI POT Click is an accessory board in mikroBUS form factor.
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.
This library contains API for DigiPot Click driver.
void digipot_cfg_setup ( digipot_cfg_t *cfg );
DIGIPOT_RETVAL digipot_init ( digipot_t *ctx, digipot_cfg_t *cfg );
void digipot_set_wiper_positions ( digipot_t *ctx, uint8_t wiper_pos );
float digipot_convert_output ( uint16_t adc_val, float v_ref );
The demo application changes the resistance using DIGIPOT Click.
The demo application is composed of two sections :
Initializes SPI and LOG modules.
This is an example which demonstrates the use of DIGI POT Click board. Increments the wiper position by 10 positions every 5 seconds.
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.
Other mikroE Libraries used in the example:
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.
