"In the blog post on the Convergence, I measured 168Hz for the FrSky converter.
That was independent of the value for parameter SERIAL_SBUS_RATE, which defaults to 50Hz.
If you have an oscilloscope or logic analyzer you should check what you're…"
"That looks good, too. Beware that some sbus to pwm converters will output frame rates > 50Hz, which might be a problem with analog servos. If you're using ESCs or digital servos, that's OK."
"Glad you like it. I just noticed that there's now a very tiny single channel converter from FrSky: https://alofthobbies.com/frsky-sd1-sbus-converter.html
Of course, without the pins and wrapper, the 4 channel one is also pretty small."
"The PixRacer does not have an analog input pin dedicated to airspeed input. I use the MS4525 and MS5525 digital sensors on I2C instead. Juan C Ricardo said:
Hi guys:
Anyone knows here if I can wire an analog speed sensor to pixracer ?

"If we rule out the power supply as the cause, that would indicate a random component failure on the Pixhawk.
Since you aren't using any non-3DR components, there would seem to be no other possible causes."
"My guess is that the safety coprocessor, or a related component has failed. I'd replace the Pixhawk and make sure that its power supply is reliable, since there's a chance the failure was caused by a spike on the power input. Are you using the servo…"
"That 72 second interval has no log entries; between log index 1527975 and 1527976, TimeUS jumps from 2070 seconds to 2141 seconds. Andre K. said:
Like Graham already pointed out, there is no yaw tuning, and if you rolled plane enough, using…"
"Hi Bill,
I finally got around to playing with this concept in multicopters, and it's looking very encouraging for estimating airspeed. Here's a plot from a quadcopter flight log where I flew circles in a "coordinated" way, and also with constant…"
"That is correct. The Pixracer's servo rail does not connect to its internal 3V3 regulator. That is powered only via the power module input and the USB port.
A "star" ground configuration will keep motor currents out of the ground connection for the…"
"Hi Joe,
You definitely have more full-scale experience than I, all of my solo time was in a Cessna 150 :)
But I'm not sure what you mean by "you can place a multicopter in a turn and perform 360 yaw spins with no adverse effects".
Certainly a…"
