POT 3 Click is a Click board� with the accurate selectable reference voltage output. By employing a high-quality 11mm, metal shaft potentiometer, this Click board can provide very accurate voltage output.
We provide a library for the Pot3 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 Pot3 Click driver.
Config Object Initialization function.
void pot3_cfg_setup ( pot3_cfg_t *cfg );
Initialization function.
POT3_RETVAL pot3_init ( pot3_t ctx, pot3_cfg_t cfg );
This function reads the result of AD conversion.
uint16_t pot3_read_adc ( pot3_t* ctx );
This function reads the averaged result of AD conversions.
uint16_t pot3_read_avg_adc ( pot3_t* ctx, uint16_t n_samples );
This function returns VOUT value calculated to millivolts.
uint16_t pot3_get_vout ( pot3_t* ctx, uint8_t vref_sel, uint16_t n_samples );
This example gets voltage, calculates it to millivolts and then logs it to the terminal.
The demo application is composed of two sections :
Initializes device and sets required pins.
void application_init ( void )
{
log_cfg_t log_cfg;
pot3_cfg_t pot3_cfg;
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
pot3_cfg_setup( &pot3_cfg );
POT3_MAP_MIKROBUS( pot3_cfg, MIKROBUS_1 );
pot3_init( &pot3, &pot3_cfg );
}
Reads VOUT value calculated to millivolts with 2000 conversions included in one measurement cycle.
void application_task ( void )
{
voltage_mv = pot3_get_vout( &pot3, POT3_VREF_2V, 2000);
log_printf( &logger, " VOUT : %d mV\r\n", voltage_mv );
}
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.
