VL53L0在使用一段时间后无法读取数据，已经有好几个模块了，返回的错误代码有-6，-7和-20，这个到底是怎么回事？如何解决？

-6 Range error        - Device reports a ranging error interrupt status Wrong API programming (syntax error), or no target present during offset calibration, or I2C transaction corrupte

-7 Time out error

   - Aborted due to time out Device is functionally failing, or I2C transaction corrupted
-20 Control Interface Error

   - Error reported from IO functions (comm error) I2C comm error
综上，问题大概率出在I2C上，需要重点排查I2C通讯。
