POT 2 Click

POT 2 Click is a Click board™ with the accurate selectable reference voltage output.

Click Product page

Click library

  • Author : Jovan Stajkovic
  • Date : nov 2019.
  • Type : ADC type

Software Support

We provide a library for the Pot2 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 Pot2 Click driver.

Standard key functions :

  • Config Object Initialization function.

void pot2_cfg_setup ( pot2_cfg_t *cfg );

  • Initialization function.

POT2_RETVAL pot2_init ( pot2_t *ctx, pot2_cfg_t *cfg );

Example key functions :

  • Generic read function.

pot2_data_t pot2_generic_read ( pot2_t *ctx );

Examples Description

This demo-app shows the ADC values using POT 2 Click board.

The demo application is composed of two sections :

Application Init

Configures clicks and log objects.

void application_init ( void )
{
    log_cfg_t log_cfg;
    pot2_cfg_t 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.

    pot2_cfg_setup( &cfg );
    POT2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    pot2_init( &pot2, &cfg );
}

Application Task

Demo app reads ADC data and displays them as dec and hex values every second.

void application_task ( void )
{
    pot2_data_t tmp;
    
    tmp = pot2_generic_read ( &pot2 );
    log_printf( &logger, " ADC value : [DEC]- %d, [HEX]- 0x%x \r\n", tmp, tmp );
    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.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Pot2

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.
