PWM update frequency

Hi All, I was wondering if it is possible to increase the frequency with which the PWM values are published in a vanilla crazyflie. From this post https://forum.bitcraze.io/viewtopic.php?f=5&t=1405&sid=106e883fc5c4a70a95fd052a6e21d466 , I take that the PWM frequency is 328kHz, so I guess we could up...

Bolt ESC Calibration

Hi All, I've been trying to use a crazyflie Bolt with a 4 in 1 ESC (it has BLHeli) and I am having an issue with recalibrations. Each time I turn on the quad, I go to an unknown calibration state. :( Since my ESC goes over the recommended maximum current the Bolt can handle, I am connecting it direc...

Replace damaged processor

Hi all, I've just purchased a Crazyflie Bolt, but due to me being a bit to eager to set it up, I've soldered the power and ground pins on one of the ESCs the wrong way. :( This blew the ST processor and the MOSFET connected to that ESC, but I was wondering if it is still salvageable. I checked the s...

External Antenna

Hi, Noob here. I have a strange issue that my crazyflie 2.1 with a bigquad deck seems to lose connectivity very easily. I am not sure why this is happening, but I wanted to test an external antenna and see if that would solve the issue. I found this https://wiki.bitcraze.io/projects:crazyflie2:hardw...

Re: BigQuad deck ESC PWM signal not changing

I found the bug. Will probably make a ticket about it in the github repo. line 84 extRxInit(); in function bigquadInit in bigquad.c static void bigquadInit(DeckInfo *info) { if(isInit) { return; } DEBUG_PRINT("Switching to brushless.\n"); motorsInit(motorMapBigQuadDeck); //extRxInit(); #ifdef BQ_DEC...

Re: BigQuad deck ESC PWM signal not changing

Hi All, I've been trying to debug this for a while now, so I will report how far I got. When logging the thrust values from setpoint, I get thrust values coming from crtpCommanderRpytDecodeSetpoint (from crtp_commander_rpy.c), so I know I am decoding a package that is sending me thrust. I've logged ...
