Click board with the accurate selectable reference voltage output.
We provide a library for the Pot 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 Pot Click driver.
pot_cfg_setup Config Object Initialization function.
void pot_cfg_setup ( pot_cfg_t *cfg ); pot_init Initialization function.
err_t pot_init ( pot_t *ctx, pot_cfg_t *cfg );pot_read_an_pin_value This function reads results of AD conversion of the AN pin.
err_t pot_read_an_pin_value ( pot_t *ctx, uint16_t *data_out );pot_read_an_pin_voltage This function reads results of AD conversion of the AN pin and converts them to proportional voltage level.
err_t pot_read_an_pin_voltage ( pot_t *ctx, float *data_out );Click board with the accurate selectable reference voltage output.
The demo application is composed of two sections :
Performs logger and Click initialization.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
pot_cfg_t pot_cfg; /**< Click config object. */
/**
* 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.
pot_cfg_setup( &pot_cfg );
POT_MAP_MIKROBUS( pot_cfg, MIKROBUS_1 );
if ( ADC_ERROR == pot_init( &pot, &pot_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}
Reads and displays on the USB UART the voltage level measured from AN pin.
void application_task ( void )
{
float voltage = 0;
if ( POT_OK == pot_read_an_pin_voltage ( &pot, &voltage ) )
{
log_printf( &logger, " AN Voltage : %.3f[V]\r\n\n", voltage );
Delay_ms ( 1000 );
}
}
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.
