I have the APM 1.0 on my tricopter. The latest tricopter firmware was downloaded today.
It seems the motors are working correctly. IE: They respond to input from RC Transmitter and seem act correctly as the tricopter is tilted.
I cannot however get any movement from the tail servo. When looking at the APM Planner -> Radio setup it is reading my rudder input from the RC TX...the servo just isn't doing anything.
I read a couple other people with this issue...however they were able to get movement when in manual mode. The firmware I downloaded today...does not have manual mode.
I checked all the connections against the diagrams think it is correct. The servo is connected to 7 on the APM
Does anyone know how to fix this or point me in the right direction?
Cool. Thanks! When you say very soon...Do you mean possibly later today...or maybe early next week?
Probably by Sunday night PST.
By deal with arduino...do you mean compile it myself? I have not done that yet...but am a software person and willing to try.
Please send the zip.
Thank You again.
Or how hard is it to install the previous version?
Below is the code I used last night to debug the same problem on my tri. I've left all options default, except the frame type which is already set to TRI_FRAME in APM_Config.h
Previous versions are a little tricky unless someone has saved a copy. The mission planner doesn't offer a roll back option.
Instructions for compiling and setting up arduino are here below. Make sure you download the 0022 relax version (windows) or the 0023 relax for mac. Do not try and use the 1.0 version, it does not work with current code releases.
I now have my saturday night mission. The new release will probably be out by the time I get this done...but its a good project.
Sorry, wrong link to the arduino setup above. It is here:
I got this installed and working. The tail servo works now.
The servo does not have much travel though. Do fly like that, or is it due to the way you sent the settings?
Good to hear. The servo doesn't move a whole lot, especially if you are in stabilize mode. Set up the flight modes so you get acro and you might see a little more movement, but I'm pretty sure some of the movement is damped from stick input and used by the code so it can react to the gyro rate. I've noticed it moves more by picking up my bird and twisting it to and fro 90 degrees than it does with stick input.
Well...I guess its time to go fly then.
