Hi! I have a cc3d flight controller for my drone project. I would like to use the stabilization of the board and showcase a stable hovering without an RC transmitter while it is connected to GCS or, preferably, after it's disconnected with some delay. Can I generate and modify input signals from the board, if so how? Thanks!

You can control it while it's connected to the GCS. The wiki article https://librepilot.atlassian.net/wiki/display/LPDOC/Control+vehicle+using+joystick talks about using an actual joystick but the on screen image of RC transmitter joysticks it shows can also be moved with a mouse (or touchscreen) and actually works.

It will drift away the same way a car will sooner or later drift off the road if you don't keep control of it.
It sounds like what you want is a GPS position hold which will hold it there, even in the wind. CC3D cannot do that with LP firmware. You need a Revo, Nano, or Sparky2 FC.

Thanks for the answers. I will use the board as a testbed for a small frame that will be used indoor environments. Currently I'm more interested in the boards ability to keep the angles stable as possible rather than having a closed loop position control. It will be the later concern of my project with added onboard sensors.

Indoor navigation independent of GPS would be a really nice thing to have in LP and that is a really interesting topic, though CC3D has quite limited RAM and Revo or Sparky 2 might be more suitable as platform for that type of experimentation.

I'm a beginner at the hardware stuff. I'm more of a control guy, but i need to test out the frame first, so that I can go on implementing stuff. I found the board on my local supplier and bought it without giving much thought, but for the time being i guess it would do.
Another thing i would like to ask is that I'm using coreless motors which are using a basic transistor circuits for the speed control. However, in the GCS it seems that I need a compatible esc for the output. I need clear PWM signals from the output pins to be connected to the transistors. Is there a way I can get around it?

Sure, see https://forum.librepilot.org/index.php?topic=1597.msg11639#msg11639 and https://forum.librepilot.org/index.php?topic=1501.msg11312#msg11312

Thanks again for helpful answers. I'm aware that I'm asking too many questions at only one blogpost, but i just have one more :).
The GCS controller does weird twitching moves and when i move the virtual sticks around with mouse cursor they automatically center themselves, and i can't make them stay at the position i want. I checked the settings but i couldn't see the settings for it.

As long as I check GCS control to activate them they stay where I put them.

I figured the problem out. It was due to the compatibility issue with the windows 10. I used compatibility for windows 7, it works now.
