Re: Ultrasonic replacement to the zranger

Hello, Ycolmenares! I would be happy to share my code with you. Do keep well in mind that this code is still a work in progress and thus is *VERY* messy with poorly commented sections and sections removed entirely via commenting. There are also sections and functions that do not need to be in the co...

Re: Ultrasonic replacement to the zranger

Thank you for your help! After I did the procedure and set the estimator to be the kalman estimator in the config makefile, I did get numbers from the drone! :) Thanks!! Now, however, I have inevitably run across another issue. :cry: When I start up the drone, the drone does successfully start up, b...

Re: Ultrasonic replacement to the zranger

Thank you for your help, Arnaud! I however could still use some clarification. I am struggling with understanding what does what in the zranger files. I have been snooping around with it and trying to understand it a bit more. My main question has to do with these two following code snippets. I am w...

Re: Ultrasonic replacement to the zranger

Thank you, Arnaud! Your clarification of the structure, and your spotting my missing comma did the trick. Now the program will compile, which is great news! Thank you very much! Now I have another problem. The driver that compiles and builds just fine doesn't work on the Crazyflie. (v 2.0) for some ...

Ultrasonic replacement to the zranger

Hello, all! Currently, continuing on my project to make an autonomous crazyflie 2.0, I am working on using a MaxBotics ultrasonic sensor to find range in the z direction as opposed to using the actual zranger, since I intend to use the zranger to find horizontal distance for collision mitigation. Lo...

Re: Autonomous Flight and hovering

Hello! Arnaud, thank you so very much for your assistance! This process has helped me so much to learn a bunch about what is going on with the firmware in the crazyflie. Our drone now can hover on its own, and we can flash the custom firmware using the eclipse ide. We will soon start working on an u...

Re: Autonomous Flight and hovering

Hello, Everyone! First of all thank you very much for your suggestions! I have taken some time to study the example code that Arnaud had in the forum thread that he linked me to, and I feel like I understand much better how the drone can be controlled within the firmware! Thanks! :D Also, to counter...

Autonomous Flight and hovering

Hello again! I want to build a program into the firmware that instructs the crazyflie to take off, stop at a specific height, and then land. I would like to be able to do this without the crazyflie communicating with a control client. To control the height, I have a z-ranger, and I hope to control t...

Compiling in Bitcraze VM

I've found myself in a bit of a pickle. I am pretty new to this stuff, so I'm pretty sure that whatever's wrong is something that has been caused by user error. I have been trying to get the Virtual Machine to work (version 2017.03), and I finally did that successfully. The next issue I encountered ...
