hey

i looked at the changes and have two pieces of feedback:

• would suggest that you create a branch for these changes. the reason that there are other changes that need to go in (eg flightstab.h and for the programmer) and we probably need to test it abit more. i can work on the changes for the programmer. so it's better to keep it in a (SUMD+GY521) branch before we commit it back to the master. sorry about the change of mind.
• i noticed you uncommented USE_I2CDEVLIB. that is not the preferred default i2c library to use. we should use i2clight if possible. i'm also planning to deprecate the use of I2CDEVLIB since people don't usually download this library separately (one user on rcgroups had trouble compiling without it).

i'll respond to your other questions on the rcgroups pm.

thanks

Hi noobee,

No problem, do whatever you feel is better.

Concerning the USE_I2CDEVLIB, I just forgot to comment it out. But I would certainly not deprecate it. In my opinion, it could open the way to more advanced use of the MPU or other sensors (just my two cents)
