6 Reducing the driver size to its absolute minimum
Although ST have attempted to create a small driver, it might not be small enough for some applications. To
create the smallest possible driver, try the following approach:
• Use the current driver and configure the parameters as required. Start ranging (to show that it works).
• When satisfied that ranging works, dump the contents of the sensor from the location 0x2D through to 0x87.
• Replace the default register settings in the the array VL51L1X_DEFAULT_CONFIGURATION[] which is
located in the file VL53L1X_api.c.
• This makes your settings the default settings
• Your main routine then needs only to call the the VL53L1X_SensorInit() function and
VL53L1X_StartRanging().
• Most other functions can then be removed
