The Hall Current 9 Click Board™ is a compact add-on board that contains the coreless current sensor corresponding to the safety standards. This board features the CQ3300, a high-speed response coreless current sensor using a Hall sensor that outputs the analogue voltage proportional to the AC/DC from AKM Semiconductor. It employs a high sensitive InAs (Indium Arsenide) Hall element with the ability to detect both DC and AC with high accuracy and high speed. It has an ultra-fast high response of 0.5μsec, high galvanic isolation, and it is designed for the currents to range from -6.4A to +6.4A.
The Hall Current 9 Click Board™ is suitable for overcurrent applications and shows good performance in small-sized inverter applications.
Software Support
We provide a library for the Hall Current 9 Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on mikroE Github account.
Library Description
This library contains API for the Hall Current 9 Click Board™ driver.
Key Functions
void hallcurrent9_cfg_setup ( hallcurrent9_cfg_t *cfg );- Config Object Initialization function.HALLCURRENT9_RETVAL hallcurrent9_init ( hallcurrent9_t *ctx, hallcurrent9_cfg_t *cfg );- Initialization function.void hallcurrent9_default_cfg ( hallcurrent9_t *ctx );- Click Default Configuration function.
Example Description
The demo application reads ADC value and current value.
The demo application is composed of two sections :
void application_task ( void ) {
log_printf( &logger, "--------------------------rn", adc_data );
hallcurrent9_read_adc( &hallcurrent9, &adc_data );
log_printf( &logger, " ADC : %d rn", adc_data );
current = hallcurrent9_get_current( &hallcurrent9, current_offset, calc_fact );
log_printf( &logger, " Current : %.2f mA rn", current );
Delay_ms( 2000 );
}
The full application code, and ready to use projects can be installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on mikroE Github account.
Other mikroE Libraries used in the example:
- MikroSDK.Board
- MikroSDK.Log
- Click.HallCurrent9
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 Hall Current 9 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.
