MWC on 8MHz

[kos]

tested again with a 10dof from drotek , cycletime is ~4300, no noticeable impact while flying

here is the latest news for 8mhz/3.3v support : everything is working

• servo, guimbal ok


• hex and octo ok

patched files :

• output : adjust timer/counter based on F_CPU


• sensors : i2c freq calculation based on F_CPU

no need to configure anything , just select the correct board in the arduino ide

I was wondering if a 3.3V arduino Pro Mini will be able to power the WM+ module with its 3.3V. I'm not sure since my parts have not arrived yet. Anybody an idea if it is possible to run the WM+ and NK on 3.3v?

cheers,

Well, since WM+ and Nunchuk are usually connected to a Wiimote with two AA batteries...

I'm powering my WM+ with (roughly) 3.3V (5V dropped through 2 diodes), it's working flawlessly, actually, powering it with 5V is actually out of spec.

The set-up is working now, great! Still have a small problem though. In the GUI the main graph is working fine, but the roll and pitch visuals do not work.

So I figured I might have to define what type of sensor I'm using. But in the the config.h file I can see all sorts of boards and sensors but which one describes the use of just the WMP? I basically have no idea were to define that I am using a WMP as gyro sensor. Anybody know what to do?

for the roll and pitch visuals : you need an accelerometer

hey,
i want to build a small FC for 1S and so i want to use 8mhz.
is it possible to run it with the internal osc.? or should i better use an external 8 mhz osc?
thanks,
Alex
