Library Description

The library provides all the necessary functions for reading registers and writing data to the registers.

Key functions:

• void proximity8_writeData(uint8_t reg, uint16_t dataIn) - Function for writing data into the register.
• uint16_t proximity8_readData(uint8_t reg) - Function for reads data from register.
• uint8_t proximity8_getInterruptState() - Get interrupt state on the INT pin.

Examples description

The application is composed of the three sections :

• System Initialization - Initializes I2C module and sets INT pin as INPUT.
• Application Initialization - Initialization Driver init, test comunication and configuration chip for measurement.
• Application Task - Reads Proximity data and this data logs to the USBUART every 1500ms.

void applicationTask()
{
   uint16_t Proximity;
   char demoText[ 50 ] = {0};
   
   Proximity = proximity8_readData(_PROXIMITY8_REG_PROX_DATA);
   Proximity = (Proximity & 0x7FFF);

   IntToStr(Proximity, demoText);
   mikrobus_logWrite(" Proximity data: ", _LOG_TEXT);
   mikrobus_logWrite(demoText, _LOG_LINE);
   
   mikrobus_logWrite("-------------------------", _LOG_LINE);
   Delay_ms( 1500 );
}

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 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.
