Need help for reading I2C Sensor

[skimask]

From what I can see in the data sheet you should be using this:
I2CRead I2C_data,I2C_clock,$F1,[druck,druck2]
I don't know what the 0 you had there was for but the R/W bit is set by the I2CRead/I2CWrite command, you don't need to set it.

Probably should be using $F0 instead of $F1 also.
