Library Description

The library initializes and defines the I2C bus driver and drivers that offer a choice for writing data in registers and reading data from registers. The library includes functions for full Configuration chip, sets measurement distance mode, inter measurement period, timing budget and user Roi. The user has the functions available for softReset, power on procedure, read distance of the object in front of the sensor

Key functions:

  • uint8_t lightranger4_deviceConfiguration() - Functions for device configuration
  • void lightranger4_startMeasurement(uint32_t period_ms) - Functions for start measurement
  • uint16_t lightranger4_getDistance() - Function reads distance of the object in front of the sensor

Example description

The application is composed of three sections:

  • System Initialization - Initializes I2C module and set INT pin as INPUT and RST pin as OUTPUT
  • Application Initialization - Initializes the driver init, chip configuration, adjusts the LONG mode (distance measurement up to 4 meters), sets the time budget and start measurement with the adjustment of inter measurements period.
  • Application Task - (code snippet) - Reads the distance of the object in front of the sensor and logs distance to USBUART every 500 ms.
void applicationTask()
{
 while(lightranger4_newDataReady() != 0)
 {
 Delay_1ms();
 }

 distance = lightranger4_getDistance();
 IntToStr(distance, demoText);
 mikrobus_logWrite(" - Distance : ", _LOG_TEXT);
 mikrobus_logWrite(demoText, _LOG_TEXT);
 mikrobus_logWrite(" mm ", _LOG_LINE);

 measurementStatus = lightranger4_getRangeStatus();
 switch (measurementStatus)
 {
 case _LR4_MRESP_SIGNAL_FAIL:
 {
 mikrobus_logWrite( "Signal fail.", _LOG_LINE);
 break;
 }
 case _LR4_MRESP_PHASE_OUT_OF_VALID_LIMITS:
 {
 mikrobus_logWrite( "Phase out of valid limits", _LOG_LINE);
 break;
 }
 case _LR4_MRESP_SIGMA_FAIL:
 {
 mikrobus_logWrite( "Sigma Fail. ", _LOG_LINE);
 break;
 }
 case _LR4_MRESP_WRAP_TARGET_FAIL:
 {
 mikrobus_logWrite( "Wrap target fail.", _LOG_LINE);
 break;
 }
 case _LR4_MRESP_MINIMUM_DETECTION_THRESHOLD:
 {
 mikrobus_logWrite( "Target is below minimum detection threshold. ", _LOG_LINE);
 break;
 }
 default:
 {
 break;
 }
 }

 Delay_ms( 500 );
}

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.

Thermo 5 click

THERMO 5 click measures temperature in default range of 0°C to 127°C and extended range of -64°C to 191°C with ±1°C accuracy. It carries the EMC1414 temperature sensor. The click is designed to run on a 3.3V power supply.

Stretch click

Stretch click is a mikroBUS add-on board with circuitry for measuring stretch forces with conductive rubber cords. The click has screw terminals for connecting 2mm-diameter and 1m-long conductive rubber cord. The resistance of the chord increases when stretched, impacting the voltage available on the AN pin.
