Library Description

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

Key functions:

• float hallcurrent3_getCurrent()- Reads current in mA
• uint16_t hallcurrent3_readData(uint8_t reg) - Reads current data

Example description

The application is composed of three sections :

• System Initialization - Initialization of the I2C module.
• Application Initialization - Driver initialization.
• Application Task - (code snippet) - Reads the current from a bipolar current sensor and logs to USBUART every 1 second.

void applicationTask()
{
 Current_data = hallcurrent3_getCurrent();

 FloatToStr(Current_data, demoText);
 mikrobus_logWrite("Current : ", _LOG_TEXT);
 mikrobus_logWrite(demoText, _LOG_TEXT);
 mikrobus_logWrite(" mA", _LOG_LINE);
 Delay_ms( 1000 );
}

Other MikroElektronika libraries used in the example:

• I2C
• Conversions

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.
