I am using an Arduino Mini Pro 3.3V connected to a 10 DOF IMU (MPU6050, MS5611, HMC5883) from http://multicoptershop.ch (good product, nice people btw).
Communication btw. Computer (Mac oder Win7), Arduino and IMU is OK.
MultiWii/MultiWiiConf 2.0 works like a charm, but no luck with MultiWii 2.1 on the identical hardware.
The MultiWii 2.1 sketch compiles without errors, the code obviously starts, the Arduino LED is blinking, but MultiWiiConf 2.1 is not usable. You can select the com-port, but there seems to be no communication between the Arduino and MultiWiiConf 2.1.
Checked baudrate, config.h etc twice. A lot of code has changed between 2.0 and 2.1 - maybe a bug or a wrong/missing default ?
Thank you so much for your help
