"Just a quick thank-you note. Took 2.5.4 out flying today on my custom heavy 1.8kg Hexa, 1000kv Motors, and APM2.
PIDs standard apart from slightly reduced (-0.1) rate-P and stab-P.
Despite gusting 25-30km winds, flying was awesome. First time where…"
"Actually same problem here. Uploaded some recent code and always get that 20cm reading. Was also suspecting a faulty sonar as I haven't used the quad over the rainy season. I better double check then whats going on."
"Yes Rui, you should get yourself one of the piezo's that make a constant noise when you connect them to the 5V rail. Using a PWM pin would be a waste of processing power and pins unless you want your copter to play a tune ;)"
"I'll made some changes to the code, as the code that Jason had integrated was many month old and the surrounding code had changed as well. I will update/improve the piezo code and get it merged into the code base probably around end of week after…"
"In Auto Mode you should have to give it throttle to start the programmed waypoints. Its a security measure. Strange the would just start in 1-5. You can always check the output PWM values in TEST mode to verify the values. if they dont match just…"
"The wiki recommends not to use the Voltage sensor output on the ATTOPILOT, as the APM Oilpan has a better ADC.
So I have connected AN0 straight to the Lipo 3S tap (fused, just to be safe :) using the 3.9k resistor on the board.
AN1 is connected to…"
"If they are high quality (gold plated, etc) and designed to take the current I don't think there is an issue using them. The power connectors to the Lipo are connectors as well in the end and are not soldered. They take 4 times the current.
"Jason, thanks for this! Working nicely. Alt, Position Hold as well as Yaw work nicely for me. Also the Field Level Feature is great. While the 20/40 second auto trim feature is great, having the old way available (CH6 > 2Secs) was nice as it could…"
"1) Did you have to reload the code with Arduino to get the channel 7 rest to work? I looked at the code(2.0.23) and the trim_accel() function is commented out so I assume this is what you did. I just want to make sure before playing around with…"
"I initially had tried the 2.4 Series 2.5 (which are mesh type) and got quite a bit of packet loss on the serial even with low speeds. Since I changed to 900Mhz PRO (P2P,P2MP), the issues are gone and all my GCS's connect at 115200 without issue.…"
I am also using a 330xs frame, esc and motors.I have very little wobbly with the default PID, but do see a little as you described. Went out flying yesterday and have tried Altitude Hold and LOITER for a bit. Altitude with the Sonar off…"
