Re: Position Hold with Optical Flow sensor - done

Important is to know the FOV of lense. This is the distance from lense to Sensor.

Re: MultiWii 2.0 is coming

Is it normal that Baro shows negative results in GUI in pre4

If I Enable Baro on my 8" Quad it jumps 3m up and fall down and so on. I have Alt PID reduced to 0.7/0.015/7 doesn't change. The Baro curve looks good in GUI - normal up/down like a sinus curve. I have no i2c errors

Re: Integration of SRF08 I2C sonar sensor (done)

You could use a frame which reflects the range of the sensor -
- 26cm to 500cm. Each value outside = wrong
- >50cm while arming = wrong (through that my copter is 15cm over ground in total the sonar delivers wrong, I'm not able to mount it 26cm over ground)

Re: MultiWii 2.0 is coming

The Description in config.h for INTERLEAVING_DELAY is wrong. If commented out the sketch doesn't build with or without Nunchuck. So it is used also without Nunchuck somewhere in code.

Re: WinGUI public beta

@EOSBandi: without knowledge about your compile settings - maybe you can compile for x86 instead of AnyCPU. It's a setting in Studio. This solved some issues with my projects. Also just using NET3.5 instead of NET4. NET4 contains several bugs.

Think using the Serial is not an option. You should check the Sonar_update function in sensors.pde (the sketches posted in soar I2C thread). If you get the Sensor value assigened to the Sonar_Alt variable everything should work like in the standard sonar approach. Sonar_Alt is shown in GUI debug2 in...

Where to add the second code block? Which module? This block, if both lines below are depending from IF, have to be in brackets if(srf08_ctx.current >= srf08_ctx.sensors){ srf08_ctx.state=1; SonarAlt = srf08_ctx.range[0]; } otherwise only the first line is depending of the IF above

@guru_florida: Your code respects the Angle related horizon? If the Sensor is not parallel to ground the measure is wrong (while Pitch/Roll actions).

Re: Rushduino OSD - Multiwii based open software osd

A GPS on I2C always needs a separate µC (to convert the serial Data to I2C) just to do this job. So with Flightcontrol, OSD and GPS we have 3 µC. The OSD can use the GPS also for showing home direction. Additional it could provide position Data as I2C slave. This would save one µC

Re: I2C High-precision Ultrasonic Ranging Module

Would be great to have supersonic on board. Have seen such sensor in Action. It exactly follows the groundlevel during flight as long you are under 5m altitude. Because the Baro are not really exact and 0 to 5m is a critical hight for experiments it would be great to have support for.
