Re: How to fix pressure sensor LPS25H issue ?

There is a quick test you can do. After connecting with the cfclient you can force to run the system by setting parameter system->selftestPassed to 1. There is a possibility that the LPS25H I2C hangs the bus so the MPU9250 stops working as it should. Did you try compiling a FW with SENSORS_ENABLE_PR...

Re: Power Options

Fully doable but you will need some form of higher voltage transfer circuit or the losses in the tethered cables will be to high.

Re: increasing flight duration of crazyflie

There are not that many parts that can be removed, the expansion pins and battery holder maybe. Probably better to go for a bigger motor and propeller. A 7x20mm motor with matching efficient propeller is my bet.

Re: Motor connector snapped off board - part number?

I've added them to the bottom of the spare part wiki page.

Re: Big quad set up

Checking the motor signal is one thing you can try. If you don't have access to an oscilloscope you can use your multi-meter to get an idea of the signal. Since the default pwm motor driver will output a 400 hertz servo signal that is high for 1-2ms a DC measurement should show something in between ...

Re: Big quad set up

Some follow up questions, what motors are not spinning? When you power on the system do you hear all the motors making the calibrated sound that the ESC generate when they get a motor signal? Run without the Flow deck to rule out other problems. There are parameters you can set to generate raw motor...

Re: Big quad set up

The big-quad functions have gotten way to little love. Could be improved a lot but there is just not been enough time to do it. 4)The Flow HW ChipSelect (IO3) interfere with BigQuad PWM and needs to be moved. Cut trace and solder patch on Flow deck from IO3 to IO1. (What do you mean by this? how do ...

Re: Bigquad - Not Producing PWM values

Do you have another crazyflie to test with, just to rule out that there is a problem with the hardware. Also does the crazyflie calibrate? I'm can't remember but it might not send out any signal until the sensors has calibrated.

Re: FLOWDECK

I'm traveling so can't really check up the answer but I think there is already code for this. Chick in the Flow driver and there might be a parameter to turn off the flow tracking.
