Library Description

The library covers all the necessary functions to control Load Cell 4 Click board™. Library performs a standard I2C interface communication.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on mikroE github account.

Key functions:

  • void loadcell4_tare ( loadcell4_data_t *cell_data ) - Tare the scales function.
  • uint8_t loadcell4_calibration ( uint16_t cal_val, loadcell4_data_t *cell_data ) - Calibration function.
  • float loadcell4_get_weight ( loadcell4_data_t *cell_data ) - Get weight function.

Examples description

The application is composed of three sections :

  • System Initialization - Initializes I2C, set INT pin as input, set CS pin as output and start to write log.
  • Application Initialization - Initializes I2C driver and performs the power on. Sets tare the scale, calibrate scale and start measurements.
  • Application Task - This is an example that demonstrates the use of the Load Cell 4 Click board™. The Load Cell 4 Click board™ can be used to measure weight, shows the measurement of scales in grams [ g ]. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on USB uart changes for every 4 sec.
void application_task ( )
{
    weight_val = loadcell4_get_weight( &cell_data );

    log_display( weight_val );

    Delay_ms( 100 );
}


Additional Functions :

  • void log_display ( float display_val ) - Function displays readings as floating point value with two decimal places.

Other mikroE Libraries used in the example:

  • I2C
  • 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.

EEPROM 3 click carries Atmel’s AT24CM02 DIP-8 socket EEPROM chip with 256 KB of memory. The board communicates with the target MCU through the mikroBUS I2C interface (SCL, SDA pins) with speeds up to 1 MHz. The chip allows for an entire page of data to be written in a single cycle. The board is designed to use either a 3.3V or a 5V power supply.

Accel 7 click is a three-axis acceleration sensing Click board™. It uses the KXTJ3-1057, a 14bit tri-axis digital accelerometer, which can sense the acceleration up to ±16 g. This sensor is built using the proprietary Kionix micromachining technology, which results with a high accuracy and very good noise immunity.
