Usage of Wire library.

[Koepel]

the Wire.requestFrom() is followed by a Wire.available(). The return value of those Wire.available() is not used, so you may remove all those Wire.available().

When the Wire.requestFrom() returns, the I2C bus activity has finished and data is waiting in a buffer inside the Wire library. The Wire.available() return the number of bytes that are in that buffer.

Ok thanks, I will test this and update my code
