Hey Sven, My sonar is working fine and I get quite accurate values on dbg 3. But unfortuntaley the alt value is frozen at 0 all the time, which is pretty anoing It doesn't marter what value dbg 3 has. I am quite sure that this strange behaviour is just cased by a small scripting issue. May I forgot ...

Hey Sven,
I received my new 4th sonar sensor and guess what, everything, expect my quad frame which is broken , is working fine now. Damn thats abso-bloody-lutely super awesome!!!

Thanks a lot for your competent help dude!

best regards,
Felix;)

Still waiting for my new sonar...

Hey Sven, now I upoad an exemplary sonar sketch as recommended and just get the same "mindblowing" results. Serial monitor shows outof range all the time. But if i connect a radio port to the echo pin values proportinal to stick commands are shown, as it could be sawn in the screenshot bel...

Damn I am just soo stupid... closed tab during writing a post. However I made some testings today.I connected a radio chanel to D10 and defined it as AUX3PIN. Fortunately it seems like my D10 signal pin is working just fine as it can be sawen at the srceenshot below. http://www.bilder-upload.eu/thum...

Hi Sven, Congratulation you really git r done. Thats quite awesome And you are absolutely right there is a ams1117 voltage regulator befor all three serial ports. Although after switching VCC and GND to pin D10 and powering the board with an UBEC the Sonar trigger impulses are clearer and there is o...

Hi Sven, Thank you quite much for your awesome help I have already replaced the "old" def.h code with your updated one. Unfortunately I still get strange results as showen below and a lot of noise if HC-SR04 is connectet. http://www.bilder-upload.eu/thumb/e54ecb-1370105751.jpg Could it be ...

Thanks a lot for your sketch. Of course I have already tested it with both of my ultrasonic sensors. Sadly the results of my HC-SR04 aren't significantly different. I just get values between 0 and 55 and strange noise. The US-20 sonar doesn't want to deliver any values, but at least the sound pulses...

Sonar would be great pleasure.

Optical flow would also be nice buy perhabs a bit much work.

Hey Sven, Today my HC-SR04 brand new arrived . Of course I made some testing but unfortunately it seems like my HC-SR04 doesn't work properly. If i connect it to my Hobbyking Multiwii Pro board I just hear a strange noise but no trigger impulses like by my US-20 Sonar. Also double checking the code ...

Thanks Sven, pinouts are working now. Helped me quite a lot. I am using this m ... ino-148659 US-20 sonar whith a max range of 700cm instead of a hcsr04. Unfortunately it seems like the delay between every singe trig is too short for this sonar type. I only get wrong measurement like -0.27m all the ...

It seems like my multiwii pro flight controll doesn't have pin 11 and 12. Here a picture of the pinouts: http://www.rcgroups.com/forums/showatt.php?attachmentid=5383900 Caused by I have changed the Signalpins to 9 and 10. #if defined(SONAR_GENERIC_ECHOPULSE) #define SONAR_GEP_TriggerPin 10 #define S...
