Library Description

The library performs a magnetic field angle measurement and calculates angle value to degrees. The library also performs the all necessary settings for the AD conversion, for example channel selection and mode setting. For more details check documentation.

Key functions:

  • uint16_t magnrotary_readADC( uint8_t cmndByte ) - Function returns a 12bit result of AD conversion.
  • uint16_t magnrotary_outVoltADC( uint8_t cmdByte, uint16_t pwrVolt ) - Function returns ADC voltage value calculated to millivolts, depending on the VDD (power) voltage selection.
  • double magnrotary_getFieldAngle( uint8_t cmdByte ) - Function returns a magnetic field angle calculated to degrees, in the range from -90 to 90 degrees.

Examples description

The application is composed of the three sections :

  • System Initialization - Initializes peripherals and pins.
  • Application Initialization - Initializes SPI interface for communication with the device.
  • Application Task - (code snippet) - Reads a magnetic field angle calculated to degrees for channel A in Single-Ended Mode and logs results on uart terminal. Repeats operation every 300 milliseconds. Note : The angle can be measured in the range from -90 to 90 degrees.
void applicationTask()
{
    magnAngle = magnrotary_getFieldAngle( _MAGNROTARY_CHA_POS_GND_NEG | _MAGNROTARY_MSB_ZEROS_ORDER );
    
    FloatToStr( magnAngle, text );
    floatCut();
    mikrobus_logWrite( "Angle is : ", _LOG_TEXT );
    mikrobus_logWrite( text, _LOG_TEXT );
    mikrobus_logWrite( logDeg, _LOG_LINE );
    
    Delay_ms( 300 );

}

Additional Functions :

  • void floatCut()  - - Makes float value to be rounded on two decimal places.
  • void plotAngle()   - Sends results of angle on serial plotter.

 

Other mikroE Libraries used in the example:

  • Conversion
  • SPI
  • UART

Additional notes and information

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.
