Library Description

The library initializes and defines the I2C bus or SPI bus driver and drivers that offer a choice for writing data in register. The library includes function for read ambient light, hall-effect and temperature and function for detect touch. The user also has the function for initializes chip and configuration chip.

Key functions:

  • void proxfusion2_configuration() - Function for configuration chip
  • uint8_t proxfusion2_init() - Function for initializes chip
  • uint8_t proxfusion2_detectTouch() - Function for detect Touch
  • uint8_t proxfusion2_detectDark_Light(uint8_t *ALS_range) - Function for read ambient light
  • uint8_t proxfusion2_detectHall() - Function for read Hall-effect

Examples description

The application is composed of the three sections :

  • System Initialization - Initializes I2C module and sets INT pin as INPUT
  • Application Initialization - Initializes Driver init and configuraton and init chip
  • Application Task - (code snippet):
    1. Checks whether Touch is detected and measures the output detection.
    2. Measures Ambient lighting - whether it's Light or Dark, ALS range and ALS output.
    3. Checks the orientation of the magnet and measures the HALL output.
void applicationTask()
{
   mikrobus_logWrite("_________________________________________________________________________", _LOG_LINE);
   mikrobus_logWrite("| TOUCH  |  T - UI  | AMBIENT | ALS RANGE |  ALS UI  |  HALL  | HALL UI |",_LOG_LINE);
   
   // TOUCH
   Touch = proxfusion2_readByte(0x13);
   if ((Touch & 0x02) != 0)
   {
       mikrobus_logWrite("|  YES   |", _LOG_TEXT);
   }
   else
   {
       mikrobus_logWrite("|   NO   |", _LOG_TEXT);
   }
   dataRead = proxfusion2_readData( _PROXFUSION2_HYSTERESIS_UI_OUTPUT );
   IntToStr(dataRead, demoText);
   mikrobus_logWrite(demoText, _LOG_TEXT);
   mikrobus_logWrite("    |",_LOG_TEXT);

   // AMBIENT
   darkLight_ambient = proxfusion2_detectDark_Light(&ALS_range);
   if (darkLight_ambient == _PROXFUSION2_DARK_AMBIENT )
   {
       mikrobus_logWrite("  DARK   |",_LOG_TEXT);
   }
   else
   {
       mikrobus_logWrite(" LIGHT   |",_LOG_TEXT);
   }
   IntToStr(ALS_range, demoText);
   mikrobus_logWrite(demoText, _LOG_TEXT);
   mikrobus_logWrite("     |",_LOG_TEXT);

   dataRead = proxfusion2_readData( _PROXFUSION2_ALS_UI_OUTPUT );
   IntToStr(dataRead, demoText);
   mikrobus_logWrite(demoText, _LOG_TEXT);
   mikrobus_logWrite("    |",_LOG_TEXT);

   // HALL
   hall_detect = proxfusion2_detectHall();
   if (hall_detect != 0)
   {
       if( hall_detect == 1 )
       {
           mikrobus_logWrite(" NORTH  |",_LOG_TEXT);
       }
       else
       {
           mikrobus_logWrite(" SOUTH  |",_LOG_TEXT);
       }
   }
   dataRead = proxfusion2_readData( _PROXFUSION2_HALL_EFFECT_UI_OUTPUT );
   IntToStr(dataRead, demoText);
   mikrobus_logWrite(demoText, _LOG_TEXT);
   mikrobus_logWrite("   |",_LOG_LINE);
   Delay_ms(3000);
}

  • UART

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.
