LightRanger 2 click carries VL53L0X IC from STMicroelectronics, the word’s smallest Time-of-Flight ranging and gesture detector sensor. The click is designed to run on either 3.3V or 5V power supply. LightRanger 2 click communicates with the target microcontroller over I2C interface and the following pins on the mikroBUS line: RST, INT.

Library Description
The library covers all the necessary functions to control LightRanger 2 Click board. A library performs the communication with the device via I2C driver.
Key functions:
void lightranger2_writeByte( uint8_t regAddress, uint8_t writeData )
- Generic write 8-bit data function.LIGHTRANGER2_STATUS_T lightranger2_defaultConfig()
- Set default configuration function.uint16_t lightranger2_getRangeContinuous()
- Get a range measurement ( continuous mode ) function.The application is composed of the three sections :
void applicationTask() { lightranger2_startContinuous( 0 ); Delay_10ms(); distance = lightranger2_getRangeContinuous(); Delay_10ms(); if ( distance ) { mikrobus_logWrite( " Distance: ", _LOG_TEXT ); WordToStr( distance, logText ); ltrim( logText ); mikrobus_logWrite( logText, _LOG_TEXT ); mikrobus_logWrite( " mm", _LOG_LINE ); mikrobus_logWrite( "---------------------", _LOG_LINE ); Delay_1sec(); } }

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.
