debug configuration

Hello, I recently ran into a problem while debugging crazyflie with stlink. I followed the procedure: “To start debugging go into the "Run -> Debug configurations..." dialog and under "GDB OpenOCD Debugging" I find "Crazyflie 2.0". Press the debug button”. It should start the debug and hit a breakpo...

Re: The position data of crazyflie

Thank for your reply.The crazyflie flied randomly and often run into walls (when ran the 'autonomousSequence.py').One of the rotors was damaged. So I'm set only one point (0,0.5,0.5,0).I hope to find the law of crazyflie flight in flightMode.posSet mode,but I didn't. I think that when I set the poin...

Re: The position data of crazyflie

Thank you for your reply.I tested the ‘autonomousSequence.py’ script with LPS only. Though, I don't kown whether there is drift, it looks like the crazyflie didn't fly according to the setpoint I gave.I have read 'autonomousSequence.py'.I found that the function 'cf.commander.send_setpoint(position[...

Re: The position data of crazyflie

Thanks again for your reply.I have 6 anchors. I use the client in windows.There is no mode option(Auto/TWR/WDoA)(attached picture '2.jpg'). I can see a stable position estimate in the LPS tab in client(It doesn't look like much error).But I can't stabilize crazyflie with the gamepad in position hold...

Re: The position data of crazyflie

Thank you very much for your reply! I did experiments one, two, three:1)flow deck: crazyflie can hover stably only with flow deck. 2)flow deck + LPS: crazyflie also can hover stably. 3) only LPS: the crazyflie can't hover only with local position system . It will float far away and be out of control...

The position data of crazyflie

Hello, I have used the flow deck and an external camera to achieve some tracking tasks. I found that crazyflie could fly smoothly with the flow deck.However,I can't exactly know the 3D position of the crazyflie and the target so that the tracking effect can't be accurately evaluated.So recently I bo...
