Current click board

Current click board

Current click is s a compact and easy solution for adding current measurement in your design. It features INA196 current shunt monitor, MCP3201 12-bit ADC, MAX6106 voltage reference as well as two screw terminals. Current Click communicates with target board microcontroller via mikroBUS SPI (SDO, SCK, CS) and AN lines.

Library Description

The library covers all the necessary functions that enables the usage of the Current click board.
It offers reading from output register and calculations that result in relatively accurate current value.

Key functions:

  • uint16_t current_dataRead() - Function is used to read data from output register.
  • float current_avgData() - Function is used to calculate average raw data value.
  • float current_getCurrentData( float rShunt ) - Function is used to calculate current in mA.

Examples description

The application is composed of the three sections :

  • System Initialization - Initializes SPI module, LOG and GPIO structures, sets CS pin as output and AN pin as input.
  • Application Initialization - Initalizes SPI driver and makes an initial log.
  • Application Task - (code snippet) This is an example that shows the capabilities of the Current click board by measuring current in miliampers. Current click board can be used to safely measure current ranging from 2mA to 2048mA. It is important you need to provide the shunt of the appropriate value.
void applicationTask( )
{
    current = current_getCurrentData( _CURRENT_RSHUNT_10 );
    
    FloatToStr( current, logTxt );
    mikrobus_logWrite( " Current: ", _LOG_TEXT );
    mikrobus_logWrite( logTxt, _LOG_TEXT );
    mikrobus_logWrite( "mA ", _LOG_LINE );
    mikrobus_logWrite( "-----------------------", _LOG_LINE );
    Delay_ms( 1000 );
}

Other mikroE Libraries used in the example:

  • SPI
  • UART
  • Conversions

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB 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.

Load Cell 5 Click

0

Load Cell 5 Click is a compact add-on board that represents a weigh scale solution. This board features the AD7780, a pin-programmable, low power, 24-bit sigma-delta ΣΔ ADC from Analog Devices. It interfaces directly to the load cell, where the low-level signal from the load cell is amplified by the AD7780’s internal low noise programmable gain amplifier programmed to operate with a gain of 128 or 1. It also has a power-down mode allowing the user to switch off the power to the bridge sensor and power-down the AD7780 when not converting, increasing the product battery life. This Click board™ has many features that make it a perfect solution for safety-critical and weight measurement applications.
