Fiendie,
Should the timer re-enable be delayed until after ALL of the channel counters have been set by pwmWriteSyncPwm? I will post an issue on gitHub.
Nice coding BTW.

MultiWii Lite version for Atmel 32u4 Nano/Micro Quads
I have uploaded a radically cutdown Lite version of MW into the gke folder in the SVN repository. There are many many changes and in fact it is close to a rewrite. The PID control code may be of interest to the main MW guys and is adapted from UAVX. Code loop can run down to 1.3mS which is more than...

Re: MultiWii Pocket X
Increasing the PWM frequency definitely does improve the motor response and attitude hold. For the HK quad the best frequency seems to be 8KHz although some guys have gone to 16KHz to get the noise down. I have replaced the motors and props with those from a FF120 and I get 7 minutes hover at 27% us...

Re: Throttle Pid Attenuation (TPA) Explaination Please
I am curious as to how many people are actually using conf.rollPitchRate and conf.YawRate by which I mean the simple P & D gain scheduling driven by the throttle setting?
Thanks
Greg
Thanks

Re: Acc Calibration & Code mods
Probably wrong Pocket Quad but oh well. The MPU6050 accelerometer has very low temperature drift and so assuming you don't bend something a once off calibration is usually enough. What I do is put a small piece of scrap printed circuit on top of the prop hubs and a bubble float on top of that. I the...

Re: MultiWii Port to STM32F4 (UAVXArm32F4)
Thanks Hamburger.
I liked your efforts when Rabbit ripped off MultiWii. I am now one of those who thinks long and hard before releasing source. The clone guys sometimes makes me think of shutting down and just going fishing.
Have a happy and safe holiday season all.

Re: MultiWii Port to STM32F4 (UAVXArm32F4)
Thanks Alex. The source code is now in the gke branch and also posted off my repository. Most of the action is in harness which provides the hooks to the board hardware. I am using a version of Attolic as my toolset before they locked the code size down. Eclipse will also work. It should be possible...

Re: MultiWii Port to STM32F4 (UAVXArm32F4)
So TC warned me about the aggression on this Forum but I see by your posts that you are not a technical contributor. I can tell by your post, (the first one), you came here to sell something. Sorry I called you out on this but my facts remain. 1) You did not port MW 2.1, you recanted and said basef...

MultiWii Port to STM32F4 (UAVXArm32F4)
I have ported the current MW 2.1 to the board below which runs an STM32F4 at 168MHz. It took about 2 days so no particular dramas. I have made NO changes or improvements to the 2.1 core and will not be doing so as this exercise was for some comparative work. The port talks happily to all the GUIS. O...
