# Title: ADC 12 Click Board™ ## Description: How Does The ADC 12 Click Board™ Work? The ADC 12 Click Board™ is based on the ADS7828, a low-power 12-bit data acquisition device that features a serial I2C interface and an 8-channel multiplexer from Texas Instruments. The architecture of the ADS7828, which is a classic Successive Approximation Register (SAR) A/D converter, is based on capacitive redistribution that inherently includes a sample-and-hold function. It has an integrated I2C input and output port as well as screw terminal connectors for each analogue input channel. It is controlled by an internally generated free-running clock. When the ADS7828 is not performing conversions or being addressed, it keeps the A/D converter core powered off, and the internal clock does not operate. When the A/D converter enters the Hold mode, the voltage on the selected channel pin of the input terminal is captured on the internal capacitor array. The input current on the analogue inputs depends on the conversion rate of the device. During the sample period, the source must charge the internal sampling capacitor. After the capacitor has been fully charged, there is no further input current. The amount of charge transfer from the analogue source to the converter is a function of the conversion rate. The ADC 12 Click Board™ communicates with MCU using the standard I2C 2-Wire interface with a frequency up to 100kHz in the Standard, up to 400kHz in the Fast, and up to 3.4MHz in the High-Speed mode. It also allows the choice of the last two least significant bits (LSB) A0 and A1 by positioning SMD jumpers labelled as ADDR SEL to an appropriate position marked as 0 and 1. This Click board™ also posses a jumper for selecting the reference voltage labelled as VREF SEL. The ADS7828 can operate with an internal 2.5V reference or an external reference (in this case logic voltage level VCC), which can be selected by positioning SMD jumpers to an appropriate position marked as INT and EXT. The ADC 12 Click Board™ is designed to be operated with both 3.3V and 5V logic voltage levels that can be selected via VCC SEL jumper. This allows for both 3.3V and 5V capable MCUs to use the I2C communication lines properly.

IC/module: MCP3204 Analog-to-Digital Converter

ADC Click is designed using MCP3204, a 12-bit Analog-to-Digital Converter. The MCP3204 is programmable to provide two pseudo-differential input pairs or four single-ended inputs. It establishes communication with the devices using a simple serial interface compatible with the SPI protocol. It is capable of conversion rates of up to 100 ksps.

Why ADC Click is needed'

The ADC Click is needed to provide a link between the analog world of transducers and the digital world of signal processing and data handling. This accessory board allows for multiple connections with the help of its 12-bit ADC that engages itself in quantization of the input and converts the voltage periodically that is sampling the input, thereby facilitating the process of data integration.

SMD Jumpers

The ADC Click Board™ comprises of two zero-ohm SMD jumpers: PWR SEL and REFERENCE. PWR SEL allow the user to select a 5V or 3.3V power supply. The REFERENCE enable user selection of either VCC or 4.096V as the voltage reference.

We provide a library for the ADC 12 Click Board™ on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

The library covers all the necessary functions to control the ADC 12 Click Board™. Users can set or read input mode or power-down mode, read raw ADC or voltage and send commands to input register or read the output.

Key Functions

Example Description

The application is composed of three sections :

void application_task ( )
{
    mikrobus_logWrite( "Read Channel 0 raw", _LOG_LINE );
    adc_r = adc12_single_ended ( ADC12_SNGL_END_CH0, ADC12_INT_V_REF_VAL );
    WordToStr( adc_r, log_txt );
    Ltrim( log_txt );
    mikrobus_logWrite( "ADC raw: ", _LOG_TEXT );
    mikrobus_logWrite( log_txt, _LOG_LINE );
    mikrobus_logWrite( "", _LOG_LINE );
    mikrobus_logWrite( "Read Channel 0 voltage", _LOG_LINE );
    adc_v = adc12_single_ended_volt ( ADC12_SNGL_END_CH0, ADC12_INT_V_REF_VAL );
    FloatToStr( adc_v, log_txt );
    Ltrim( log_txt );
    mikrobus_logWrite( "ADC raw: ", _LOG_TEXT );
    mikrobus_logWrite( log_txt, _LOG_TEXT );
    mikrobus_logWrite( "mV", _LOG_LINE );
    mikrobus_logWrite( "------------------------", _LOG_LINE );
    Delay_ms( 1000 );
}

The full application code, and ready to use projects can be found on our LibStock page.

Additional Notes and Information

Depending on the development board you are using, you may need a 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.

mikroSDK

The ADC 12 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
