Re: CPPM receiver with BigQuad deck on the Roadrunner

Unfortunately the CPPM input does not work at the same time as the Loco deck which is integrated to the Roadrunner. It might be possible to move the CPPM to another available TIMER and PIN but that requires some investigation and coding work. Also to have the Loco deck work with the BQ-deck have you...

Re: Lighthouse with Big Quad Deck

We have not tested this yet but I think it should work. The TX1 and RX1 will be occupied by the Llighthouse deck but if you are not using the BQ-deck GPS port there should be no collision.

Re: Tuning the big quad

The PID and Mellinger are different controllers and needs different tuning. The tuning guide for the PID still works and you should be able to use that. The Mellinger controller is a different topic and I have actually never tuned it. Maybe @wolfgang could help us out. In the cfclient console window...

Re: how to alter the controller's code

The motors are using TIM2 and TIM4 so should not have a conflict with TIM5. It must be something else. Can you get it to fly if you don't compile the servodeck driver?

Re: Where I can modify the code for an asymmetry quad-rotor

Kimberly is on the right track. You will have to create a function in power_distribution_stock.c (or a new file) that distributes the power according to your geometry.

Re: Dongle communication error

One quick follow up question. Are you having the link open in the cfclient at the same time?

Re: Crazyclone

Nicely done, I hope you write more about it as you progress.

For the nRF51 there is a make target "factory_reset" this should flash bootloader and such. Here you need to use SWD

For the STM32 you need to flash first the bootloader, then the FW using the STM32 SWD.

Re: Crazyclone

It it is a crazyflie 1.0 you need to flash the 1.0 FW which is not developed any more, but can still be build. Read about it in this blog post.

PS. Would be nice to see a picture if you have :D . DS

Re: CF Ignores some of the high-level commands

I have not used the ros driver that much but I know there is a broadcast functionality. I'm guessing you are not using this? There is no acknowledgement that a packet has been processed by the STM, only that it has been received by the NRF, so potentially something could get lost there, but I doubt ...
