I was wondering if I have to upgrade the CrazyRadio, if so, how do I do it?
Thanks.

Hello, I am trying to flash the firmware with the new update of the PCClient, but I can't, I am using Windows Vista, I get this error: ******************************************************************************************************** Traceback (most recent call last): File "\bitcraze-craz...

Hello, I was wondering if anyone knows how much is the current draw of the CF??? The datasheet says the battery has a capacity of 170mAh, then the battery has a continious discharge rate of 25C. That means capacity * discharge rate = 4.25 A / 4 motors = 1.0625 A each motor max. If we apply a safety ...

Hello, I do not have an account on bitbucket yet, : P. I was doing more testings and it seems the calibration does not work if the CF is tilted too much. More over, I think only the hard iron calibration is needed, the one that adjust the offset of the readings. Below is a graph of the raw data: mag...

It is working! The yaw reading is spanning 360 degrees and it does not drift. I had to get lots of data to do the calibration and I removed data out of range.
X axis: Data point
Y axis: Angle

Hello, I am trying to implement an autopilot in the Crazyflie. I have been making some changes to the firmware to implement a new control law. For that I need to know the orientation in pitch, roll and yaw. I already added gyro drift subtraction for pitch and roll, and the readings seems to be right...

Hello, I am able to control the motors from the cfclient changing the values in the firmware :) !!!. Now, something I noticed, is as explained in the wiki, "Sending a command makes it apply for 0.5 seconds, after which the firmware will cut out the power". After navigating the firmware cod...

Hello, I am trying to turn on the motors from the cfclient using: self.crazyflie.param.set_value("motor.m1", 10001) but I get the following warnings: Fri, 16 Aug 2013 19:12:36 WARNING cflib.crazyflie.toc Unable to find variable [motor.m1] Fri, 16 Aug 2013 19:12:36 WARNING cflib.crazyflie.p...

Hello, Thanks, the following is already in the firmware, in module \modules\src\stabilizer.c: LOG_GROUP_START(stabilizer) LOG_ADD(LOG_FLOAT, roll, &eulerRollActual) LOG_ADD(LOG_FLOAT, pitch, &eulerPitchActual) LOG_ADD(LOG_FLOAT, yaw, &eulerYawActual) LOG_ADD(LOG_UINT16, thrust, &actu...

Hello, I was trying to read some variables from the Crazyflie on the Windows side, when I read the accelerometer or the gyro axis with: allVar_log_conf.addVariable(LogVariable("acc.x", "float")) allVar_log_conf.addVariable(LogVariable("gyro.y", "float")) every...
