I want to learn the source code of PX4, but I donât konw how to begin.At the moment, I just read the source code aimlessly. I want to read and modify the part of control, making my drone fly in the sky. I read the tutorial about wrinting a âhello skyâ on the website, but I failed to find a tutorial, which teaches me how to read the code of control, and how to modify it. Can anybody offer me a way to make it? Thank you very much!
OK, I will read it. Thanks!
Thank you for your sharing of ppt, and I have read them all. Iâm now interested in how to read the part of âExample project: custom controller for a non-conventional vehicleâ on your website. It seems that it consist of four parts,â1. System analysis and modellingââ2. Implementation in a Hardware-In-The-Loop simulatorâ,â3âŠââ4âŠâ, which Iâm interested.Could you tell me how I can get and read the contents? I canât find an available link.Thank you!
This is not another tutorial. This is an example workflow of what I do for work as a consultant.
Thank you for your reply. Iâm a bit curious about how long did it take for you mastering PX4? I have spend a lot time trying to comprehend the framework of PX4. For example, I spend all week night trying to find the function âmainâ of PX4. But I found it doesnât have a funtion of main at all eventually. Instead, it uses a rcS to start and initial the whole system. Iâm now trying to find out how the whole system run?I think it is linked with the concepts of âtaskâ and âwork_queueâ. But Iâm still havenât found its entry point. Can you tell me, where can I find it? Iâm sorry for replying to you late. Recently, I have been quite busy with some annoying things.
Hello! I have met a question when I analyze my data. Could you help me please?
I placed the quadrotor on my desk for some minutes. And I download the data and analyze them on flight review. I find the acceleration of x, y and z almost constant number 0 and -9.8 m/s2. But I find the âacceleration power spectral densityâ puzzling. I cannot find a yellow line at 0 Hz, which represent the constant number of
0 and -9.8 m/s2. How can we explain this phenomenon? Or does it have some problem?
Iâve been writing a blog post about this, hopefully coming soon
