WM+ BMA020 on Mega not working with 1.9

[Th0rsten]

Hello!

I just build my Mega-FC with parts from flyduino.com
The problem: In 1.8.2 everything works fine and fast with about 4200 cycle time.
In 1.9 there are no readings from the gyro and ACC is very slow - there are errors on the i2c.
Yes, I'm aware of the i2c-error posting here in the forum but as you can see on the picture - it's hard to mess up wiring.
Internal pull-ups are enabled.

Update1: Commented the BMA020 in the 1.9 and now I get readings (with no i2c errors) from the gyro.
It's like here: viewtopic.php?p=6063#p6063

Update2: Switched from 3V3 to 5V for the WM+. Same bad results.

Update3: Connected 2k2 external pull-ups from SDA and SCL to 5V and disabled internal pull-ups. WM+ still on 5V.
GYRO AND ACC ARE WORKING with no errors on i2c!!!

Update4: viewtopic.php?f=8&p=7456#p7456

It's sad that buying a plug'n'play solution wasn't so plug'n'play.
Despite the problem with the pull-ups the Flyduino MEGA and the Flydusense V1.2 are build very well.

Indeed, found out that you have to add 2k2 pullups to the sda & scl. It works now. Congrats ! I ordered also a Drotek 6DOF IMU to have a better flying experience. Will use the WM+ and BMA anyways!

By the way, why did you buy a flyduino MEGA? Well, what advantages did you have with it. Thanks for sharing!

Wanted something looking a bit more professional than my first quad with homemade FC and DIY OSD.
And I want to be ready for GPS.

It is already looking good! By the way, do you come from Belgium or the Netherlands? Because your name is dutch (Thorsten), could be wrong.

Nice GoPro HD too !

Very nice ! I love it, also love the place where you fly, the lightning is cool! Is it difficult to fly with gyro & accel?
