APM_radio_test.pde not outputting PWM values properly

Started Oct 19, 2012 0 Replies

Can't seem to get the APM_radio_test to do what I think it should do (output pwm values from the receiver)...I'm using APM2.0, Arduino IDE 1.0.1, and arduplane 2.65 all on Win7 machine. I can…Continue

Won't go below default altitude when trying autoland

Hi, I'm having trouble getting my plane (APM2.0) to autoland.  It seems that for a given waypoint course (T3-2) it doesn't want to go below the default altitude.  I've attached my WP file and a log…Continue

Parkzone radian ardupilot parameters

Started this discussion. Last reply by David Hertzog Aug 2, 2012. 4 Replies

Hi, was wondering if anyone had a parameter file for a stock parkzone radian that worked well.  I've been trying to get mine tuned around a square course but haven't been able to dial it in yet.Continue

How do you repeat a mission?

Started this discussion. Last reply by David Hertzog Apr 11, 2012. 2 Replies

I've got 4 WPs set up in square pattern (and the home position also) and want my plane to repeat the pattern indefinitely (e.g. WP1->WP2->WP3->WP4->WP1->WP2...and so on). I tried…Continue

APM_radio_test.pde not outputting PWM values properly

Can't seem to get the APM_radio_test to do what I think it should do (output pwm values from the receiver)...I'm using APM2.0, Arduino IDE 1.0.1, and arduplane 2.65 all on Win7 machine. I can successfully compile/upload the arduplane.pde and my servos respond correctly...but when I upload the APM_radio_test.pde the values all stay at 1200, regardless of how I move the tx sticks & swithes. Any suggestions?See More

"I believe it's the Mediatek MT3329, (I think that's what came with the APM2.0 kit, I'll have to check tonight).  One thing to note, from the log files (when I view the kmz in google earth) it's obvious it seems to be…"

"I'm having a bit of trouble with autoland too .... but just that the accuracy leaves a lot to be desired (APM2.0) so I really need to steer it in via rudder and even then it's a pretty heavy landing. Any autolanding experts out there…"

David Hertzog replied to David Hertzog's discussion Parkzone radian ardupilot parameters
"Andy, I've gotten down to some parameters that work relatively ok...I've found the plane still weaves a bit when there's a headwind, and that may just be due to the slow flight and/or rudder only control.  But the plane can…"

"hi Chris, i realize your posts on this are over 2 years old now, but was wondering if you ever got your radian tuned and if so, what your parameter file looked like. Thanks,David "
