DIGI POT 5 click is a digitally controlled quad potentiometer, with the resistance of 10KΩ. It has an 8bit wiper step resolution, which allows the wiper to take 257 different discrete positions (across 256 internal resistors). The digital wiper position can be controlled via the SPI interface.
We provide a library for the DigiPot5 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 DIGI POT 5 Click driver.
digipot5_err_t digipot5_init( digipot5_t *ctx, digipot5_cfg_t *cfg );
digipot5_err_t digipot5_generic_write( digipot5_t *ctx, digipot5_reg_t reg_addr, uint16_t data_in );
digipot5_err_t digipot5_generic_read( digipot5_t *ctx, digipot5_reg_t reg_addr, uint16_t *data_out );
digipot5_reg_t digipot5_increment_wiper( digipot5_t *ctx, digipot5_reg_t reg_addr );
This example demonstrates the use of the DIGI POT 5 click board.
The demo application is composed of two sections :
Initializes all necessary peripherals and pins used for the DIGI POT 5 click. Also allows the device to be reset and configured to enable all wipers (4). UART console module will be initialized also in this function.
Demonstrates the use of click driver functions by performing a control of the all wipers positions. By checking the uart console, user can be informed about the all current wipers positions.
Increment/decrement command can be issued only to volatile wiper locations.
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.
