app_tof.c  ->  /BLE_MeshLightingPRFNode/Application/Core/app_tof.c

- void MX_TOF_Init(void)

  : Initialize the TOF sensor. Validates whether it is properly connected and starts the sensor

- static void MX_VL53L8CX_SimpleRanging_Process(void)

  : Read and print out the data if the sensor is properly running

- void MX_TOF_ToggleReso(void)

  : A public function that calls toggle_resolution. Change the resolution of TOF sensor

You can change the ranging frequency by modifying "RANGING_FREQUENCY" public variable(Set to 20Hz in the code)

*custom_ranging_sensor.c  ->  /BLE_MeshLightingPRFNode/Application/Core/custom_ranging_sensor.c

- int32_t CUSTOM_RANGING_SENSOR_Start(uint32_t Instance, uint8_t Mode)

  : Start the TOF sensor

- int32_t CUSTOM_RANGING_SENSOR_Stop(uint32_t Instance)

  : Stop the TOF sensor

TCS3430.h  ->  /BLE_MeshLightingPRFNode/Drivers/BSP/TCS3430/TCS3430.h

- Includes all the address of the registers of TCS3430

- Includes Prototype of functions

- struct tcs3430_optics_val

    : Has X,Y,Z, and IR values

- struct tcs3430

    reginfo -> data in the registers

    XYZinfo -> Low & High byte of X, Y, Z, and IR1
