- CIC Prefix : HALLCURRENT2
- Author : Katarina Perendic
- Verison : 1.0.0
- Date : Feb 2018.
We provide a library for the Hall Current 2 Click 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
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 );
}
${EXAMPLE_ADDITIONAL_FUNCTIONS}
The full application code, and ready to use projects can be found on our LibStock page.
Other mikroE Libraries used in the example:
- UART Library
- Conversions Library
- C_String Library
- I2C Library
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.
