Delay in logged data?

Hi, I've managed to implement a LQ-regulator for the crazyflie. I calculate the feedback matrix on the client and send this matrix and the setpoint to the crazyflie. There I calculate according to the actual gyro data and euler angles the necessary control for the motors. This works. Now I want to s...

Re: Where is the self test?

Hi, hal/src/imu.c There should be somewhere this code #ifdef IMU_ENABLE_PRESSURE_MS5611 if (ms5611Init(I2C1) == TRUE) { isMs5611Present = TRUE; DEBUG_PRINT("MS5611 I2C connection [OK].\n"); } else { DEBUG_PRINT("MS5611 I2C connection [FAIL].\n"); } #endif So remove at the beginning of the file this ...

Re: How to convert movements into RPY?

Hello, the cf-client gets the data for example from the connected usb-controller (roll, pitch, yaw, thrust), packs them and sends this data via radio to the crazyflie (send_setpoint in client/lib/cflib/crazyflie/commander.py). There in "modules/src/commander.c" the data gets "unpacked" and saved in ...

Re: Sending data with more than 240bits to commander

Hi Arnaud,

thank you for your reply. Meanwhile I also think that my C++ code on the Crazyflie crashes. I suppose because of some casting-issues. I will figure it out.

[SOLVED] Sending data with more than 240bits to commander

Hello, the title already says it: I want to send more than 240 bits to the commander. In fact i need to send the roll, pitch, yaw, thrust and a 4x6 matrix containing float-values to the commander. I've already compressed the data (lossy) but it's still to large. So my idea was to split the data and ...

But if I click on conne...
