ADC 5 click

ADC 5 click is a Click board™ used to sample an analog voltage on the input and convert it to a digital information. ADC 5 click is equipped with the ADC121S021, a low power, single channel 12-bit CMOS analog to digital converter (ADC), with a high-speed serial interface.

Click library

• Author : MikroE Team
• Date : Dec 2019.
• Type : SPI type

Software Support

We provide a library for the ADC5 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 ADC5 Click driver.

Standard key functions :

• Config Object Initialization function.

  ‍void adc5_cfg_setup ( adc5_cfg_t *cfg );

  - Initialization function.

  ‍ADC5_RETVAL adc5_init ( adc5_t *ctx, adc5_cfg_t *cfg );

• Click Default Configuration function.

  ‍void adc5_default_cfg ( adc5_t *ctx );

Example key functions :

• This function calculates the ADC voltage data.

  ‍uint16_t adc5_get_voltage ( adc5_t *ctx );

  - This function reads the ADC voltage data.

  ‍uint16_t adc5_get_data ( adc5_t *ctx );

  Examples Description

‍This example showcases how to initialize and configure the logger and click modules and how to read and display ADC voltage data from the click.

The demo application is composed of two sections :

Application Init

‍This function initializes and configures the logger and click modules.

void application_init ( )
{
    log_cfg_t log_cfg;
    adc5_cfg_t cfg;
 
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );
    Delay_ms ( 100 );
 
    //  Click initialization.
 
    adc5_cfg_setup( &cfg );
    ADC5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    adc5_init( &adc5, &cfg );
}

Application Task

‍This function reads and displays ADC voltage data every second.

void application_task ( )
{
    uint16_t adc_value;
    
    adc_value = adc5_get_voltage( &adc5 );
    log_printf( &logger, " * Voltage: %d mV * \r\n", adc_value );
    Delay_1sec( );
}

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.ADC5

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.
