Re: V2.2 - ACRO PID implementation is wrong, right?

I started with defaults. But if then already are oscillations I would first check that props are balanced before I would cut roll, pitch and yaw pid to 1/2 for the next attempt. Do not reduce to 0, you would not have any stabilization at all.

Re: V2.2 - ACRO PID implementation is wrong, right?

Here is PIDs for my 320 size Warthox frame, 8x4.5 props on A2208/17 1100kv, 3S 2200, AUW: 600gr http://www.multiwii.com/forum/download/file.php?id=2346 Tuning was as usual, in order P I D, raised each until oscillating then reduced to about 3/4. Did not do any tuning to yaw. Later during the flights...

Re: V2.2 - ACRO PID implementation is wrong, right?

I took a look at the source codes, for PID_CONTROLLER == 2 the errorAngle calculation is errorAngle = constrain((rcCommand[axis]<<1) + GPS_angle[axis],-500,+500) - angle[axis] + conf.angleTrim[axis]; //16 bits is ok here what should be errorAngle = constrain((rcCommand[axis]<<1) + GPS_angle[axis],-5...

Re: V2.2 - ACRO PID implementation is wrong, right?

what a helpful statement. Works well - at least care to mention what coptertyps which modes what pids you referring to? Repeating your bashing of mwii s/w and h/w is rather boring. Do you have anything useful to offer here or just dumping some emotional garbage? Please stick to your preferred futur...

Re: V2.2 - ACRO PID implementation is wrong, right?

For any reason the trunk version behaves different to original AlexK. I already tried some weeks ago, angle mode was like acro. Now as I read this I gave it one more try on my Flydumini, I raised pid to 10.0 0.060 20 and still feels like acro. I will revert again to the original where all is fine wi...

Re: V2.2 - ACRO PID implementation is wrong, right?

... The D of the original Controller is based on this: delta = gyroData[axis] - lastGyro[axis]; The D of the other Controller boils down to this: delta = - gyroData[axis] - lastGyro[axis]; ... Just a typo here in the text? I did not check the coding. Unary- has higher precedence than arithmetics, c...

Re: Auto arming motors and leveling when thrown

Yeah, this would be cool. But I fear other priorities will be set. Anyway: +1!

I have the same arming issues and need to do this via switch. Have this since r1240, r1177 was OK.

Re: Using Arduino to flash ESC

Hi,

a tutorial how to use the arduino as AVR ISP you find here: http://arduino.cc/en/Tutorial/ArduinoISP

I tried it to flash the bootloader to an arduino based I2C GPS, it worked fine.

Re: Add RTH as Fail safe
