Library Description

This library provides basic functionality for reading the current value and controlling the Click board.

Key functions:

void hallcurrent2_reset() - Function for reseting the click board sensor.

int16_t hallcurrent2_getData() - Function that returns the 12bit digital value.

int16_t hallcurrent2_getCurrent() - Function that returns the current value.
 

Examples Description

The application is composed of three sections:

• System Initialization - Initializes I2C module and INT pin as INPUT and RST pin as OUTPUT.
• Application Initialization -  Initializes Driver init and reset chip.
• Application Task - (code snippet) - Reads current and logs on usbuart every 1 second.
  It was tested with 1V voltage at the input and with a load of 1 - 2A.

void applicationTask()
{
 CurrentData = hallcurrent2_getCurrent();
 IntToStr(CurrentData, text);
 mikrobus_logWrite("--- Current :", _LOG_TEXT);
 mikrobus_logWrite(text, _LOG_TEXT);
 mikrobus_logWrite(" mA", _LOG_LINE);
 Delay_ms( 1000 );
}

Other mikroE Libraries used in the example:

• UART Library
• Conversions Library
• C_String Library
• I2C Library

Additional notes and information

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.
